Gardening Resources. Home » Reachables ® Fruit Tree Variety Pack. Reachables ® Fruit Tree Variety Pack Harvest faster--and without a ladder!

Includes 3 of our best-selling Reachables ® varieties Full-sized fruit on smaller trees Produces fruit in two years or less No ladder required for picking, pruning or netting Imagine an easy-care orchard in your own backyard. With Reachables ® , you can grow apples, peaches and plums just about anywhere, and harvest fruit in two years or less!

A Reachables tree produces full-sized fruits, but on a smaller tree. Hanging sticky traps to catch adult codling moths can be part of an overall management protocol, but traps are not effective on their own.

Tolerating some level of damage is also recommended, as the codling moth is nearly impossible to completely eradicate. Infected parts of the fruit can be cut away, and the rest is still edible. If chemical management is warranted, apply when larvae have just emerged from the eggs.

If the larvae have already entered the fruit, they will be protected from pesticides. Oriental fruit moths Grapholita molesta attack peach, plum, cherry, and apple trees Figure 15— The first-generation larvae tunnel into the ends of new shoots, causing shoot dieback Figure 15— Later generations feed inside the fruit.

Fruits near the top of a tree that are beginning to color are the first to be attacked, so take samples from there. Placing pheromone traps in the orchard in early spring to disrupt mating is the preferred treatment strategy.

The braconid wasp Macrocentrus ancylivorus is a natural parasite to oriental fruit moth and peach tree borer larvae. Planting sunflowers will encourage the braconid wasp population. Avoid broad-spectrum insecticides, which negatively affect populations of Macrocentru ancylivorus.

Plum curculio Conotrachelus nenuphar attack several soft fruits, including plums and apricots, and can cause superficial damage to apples Figure 15— Adults are brown, black, and gray mottled weevils that overwinter in wooded areas and become active at bloom time.

Eggs are laid in crescent-shaped flaps cut in the fruit skin shortly after petal fall. Larvae hatch and feed inside the fruit. Sanitation is important. Remove and dispose of damaged or fallen fruit. In early morning, place a tarp under trees and shake branches.

The adult weevils are slow-moving in the morning and will fall from the tree where they can be crushed. Use a registered insecticide after petal fall to ensure pollinators are not affected. Peach tree borers Synanthedon exitiosa attack the trunk and lower branches of stone fruit trees and other members of the Prunus genus, causing sap to ooze from the wounds.

Adults are black and orange moths but look and behave like wasps Figure 15— The cream-colored larvae have a brown head and can reach 1½ inches in length. They tunnel under the bark, and over several years they can girdle the tree. Parasitic nematodes are a treatment option, but results vary.

A registered insecticide will be most effective against egg-laying and will kill tiny larvae when they hatch. Apply it at the base of the trunk several times throughout the growing season, especially in early September when adult moths emerge.

San Jose Quadraspidiotus perniciosus and white peach scales Pseudaulacaspis pentagona Figure 15—45 overwinter as nymphs and start feeding as soon as sap begins flowing in the tree. Infested leaves usually drop, and branches lose vigor and die. Biological predators, such as the twice-stabbed lady beetle Chilocorus stigma , or parasites like chalcid and aphelinid wasps, are effective against scale insects.

Use a dormant oil spray at two-week intervals with good spray coverage just before bud break, or treat with registered insecticide when crawlers are active. Spider mites Tetranychus urticae suck juice from peach tree leaves, creating stippling and causing leaves to turn yellow or red Figure 15— Spider mites produce webbing colonies, especially on the undersides of leaves.

Hot, dry weather that causes water stress encourages their development. Spider mites have many natural enemies, including predatory mites and thrips that, if supported by limiting broad-spectrum insecticides, naturally keep populations in check.

A strong water spray, horticultural oil , or soap spray are other management strategies. Be sure to reach the undersides of leaves. Catfacing is the pitting and fruit deformity caused by adult insects with piercing-sucking mouthparts, such as lygus bug, stink bug, tarnished plant bug, and boxelder bug.

These insects damage both pome and stone fruits Figure 15— Weeds are the primary food source for these insects, so keeping weeds to a minimum around the orchard will help manage populations.

Several parasitic wasps and predatory insects, such as big-eyed bugs, assassin bug, damsel bugs, and crab spiders, attack these insects. Reducing the use of broad spectrum insecticides helps these biological predators keep pest populations in check.

Use of an insecticide is a last resort to prevent substantial fruit damage. Bacterial spot Xanthomonas arboricola is a bacterial disease on peach trees that results in irregularly shaped lesions on the leaves Figure 15—49 and sunken lesions on the fruit. Prevent it by growing resistant cultivars and spraying dormant trees with copper bactericides.

Pecan weevils Curculio caryae attack the nut Figure 15— The weevil punctures the nuts in early August Figure 15—51 ; the larvae feed within the nut, causing some nuts to fall in a few days. Pecans damaged early in the season fall off with the shuck attached.

Nuts damaged later in the season fall from the shuck with a small hole in the shell where the larvae have exited. Stink bugs Pentatomidae puncture nuts before and after nut hardening.

This puncture causes nut drop or black-spotted bitter kernels Figure 15— Twig girdlers Oncideres cingulate cut off the vascular system of twigs and small branches, causing them to drop in September. The branches appear as if cut with pruners Figure 15— Dispose of fallen shoots because they contain eggs for the next generation of twig girdlers.

Brown rot Monilinia fructicola is the most common problematic fungus and occurs during bloom. It kills blossoms and then reoccurs two weeks to three weeks before harvest on ripening stone fruits. The rotted areas are soft and brown. Brownish-gray mold covers the rotted areas Figure 15— Infected fruits often shrivel, gradually turning into hard, wrinkled black mummies.

To avoid brown rot, plant resistant cultivars. If trees become infected, remove and destroy infected fruit and branches. Prune the trees to improve air flow, and avoid overhead watering to keep foliage dry.

If problems persist, use a registered copper-based fungicide. Cedar apple rust Gymnosporangium juniperi-virginianae occurs on apple and crabapple trees. It causes small bright-yellow spots on the leaves in early summer that enlarge and turn orange with black specks in the center Figure 15— A cup-shaped structure forms on the underside of each infected leaf Figure 15— The disease organism spends part of its life on cedar trees, where it produces structures that release spores from orange gelatinous appendages in the spring Figure 15— Cedars as much as ¼-mile away can serve as alternate hosts so if infestation is severe remove all cedars in a ½-mile radius.

Apply a registered fungicide from early pre-pink through petal fall for fruit infections and from pre-pink through second cover for leaf infections. Fire blight Erwinia amylovora is a bacterial disease that is spread by bees during bloom on pome fruit trees and their relatives.

New shoots rapidly turn black at the tips and die, with blackened leaves remaining attached to the stem Figure 15— Newly infected wood has pink-orange streaks. Fire blight is most easily spread when temperatures are between 75°F and 85°F with high humidity or precipitation.

Choose resistant cultivars. Avoid heavy pruning and high nitrogen fertilizers, which cause rapid, tender growth that is most susceptible to fire blight. Do not irrigate trees during bloom, and remove and discard any infected tissue in summer or winter when the disease is inactive.

Copper products are the only chemical management available to homeowners, and they are difficult to time and apply effectively. Peach leaf curl Taphrina deformans occurs just after bloom and causes unfolding terminal leaves to blister, swell, and curl.

The stunted leaves turn reddish-purple and fall off Figure 15— New stems are stunted and distorted. Cool, wet weather when leaves are emerging favor the disease.

To avoid peach leaf curl, plant resistant varieties. For already infected trees, treat with a registered fungicide yearly after leaf fall. Peach scab Cladosporium carpophilum causes small, round, dark, olive-green - to - black spots to form near the stem end on nearly full-grown fruit Figure 15— Severely infected fruit can crack, shrivel, or not ripen.

The fungus overwinters in light-brown lesions appearing on new twig growth. Water splashes these lesions and moves spores onto the fruit.

Spring and early summer in North Carolina provide ideal growing conditions. All peach varieties are susceptible to scab, though some more than others.

The worst infection usually occurs during the first fruiting season, or around the third growing season after planting. Avoid low-lying planting sites, and prune trees to maintain good air circulation.

Powdery mildew Golovinomyces cichoracearum is a whitish-gray powdery mold that occurs on buds, young leaves, and green twigs Figure 15— Leaves may be crinkled or cupped upward, dwarfed, narrow, and erect. Plant resistant varieties and maintain good cultural practices.

Prune out infected areas during dormant season and use a registered fungicide if necessary. Apple scab fungus Venturia inaequalis causes dull, smoky spots on young leaves and petioles Figure 15— The spots later turn olive-green, then blacken and drop off the tree.

The secondary infection on the apple fruit produces lesions that cause the fruit to become deformed, knotty, and cracked Figure 15— This fungus overwinters in fallen leaves on the ground.

Cool, wet weather favors infection, and new leaves are most susceptible. Avoid overhead watering, and prune trees to promote good air circulation.

In autumn, remove any fallen leaves, spray trees with urea to hasten leaf fall, and apply lime to fallen leaves to prevent the spread of infection.

Use a registered fungicide at the first sign of greening leaves in the spring. gailhampshire, Flickr CC BY 2. Patrick Clement, Flickr CC BY 2. Eric R.

The tree has shed its leaves and remains dormant until spring. It is possible to see the entire tree structure and make informed decisions about where to prune.

Fertilize in late winter. During early spring, gradually increase irrigation as temperatures rise. Add a new layer of mulch around the base of the tree, avoiding the trunk, to help conserve water and manage weeds. Fertilize trees only if they show pale leaves and weak growth.

Be sure to follow label directions; do not fertilize young fruit trees as this can slow their maturation. Flowering, pollination, fruit set, and abundant vegetative growth occur in spring.

Thin fruit, and remove unwanted vigorous shoots to begin summer pruning. Scout for any insect or disease problems, and address them promptly. Monitor rainfall and irrigate trees deeply if necessary.

Some varieties of tree fruits ripen in summer. Taste fruit to check for ripeness and harvest, if necessary. If fruit spurs and leaves are breaking off when you pick the fruit, it is not ready to harvest. Continue to shape the tree with summer pruning, removing unwanted vigorous shoots. Scout for any insect and disease problems, and address them promptly.

Harvest varieties of tree fruit that ripen in fall. Do not leave fruit on the tree too long before picking, as this can attract pests and diseases. Chlorophyll production ends, and as it disappears from the leaves, other pigments become visible with a color display prior to leaf drop.

Water trees into October so they are not drought-stressed going into winter. Avoid pruning in fall when fire blight is active.

Add a layer of mulch to insulate the roots from cold temperatures. Rake up and dispose of any diseased or insect-infested leaves, twigs, and fruits to avoid spreading problems to healthy trees. Some of the peaches are shriveled. You have noticed that the peach trees have had this condition in the past and it seems to get worse every year.

Use the steps outlined in chapter 7, " Diagnostics " to help you identify the problem. The following questions will help. Step 1. Step 2. Describe the problem: Many of the peaches are rotting on the trees. Some are wrinkly with a fuzzy substance covering them and some have brown spots on them.

What does the healthy part of the plant look like? What does the unhealthy part of the plant look like? The unhealthy fruit has brown, fuzzy spots, and is rotten and shriveled. Have you had a soil test? Are there any significant water issues? A lot of rainfall occurred in early spring.

There was standing water around the trees for several days at a time. Describe the light. How many hours of sunlight? The peach trees receive 9 hours of full sun. Describe any recent changes or events: A lot of rain occurred in early spring. Now in June the rain is intermittent.

There have been no other changes around these trees. On the leaves : I do not see signs of insects, a fungus, or a disease. There are no spots or missing pieces of the leaves. On the stems: I do not see signs of insects, a fungus, or a disease.

On the roots and in the soil: I do not see anything near the roots. Some dried or rotting fruits are on the ground, and some have flies and fly larvae on them. More blooms died and turned brown during the spring rains. On the stems: Most stems have smooth reddish-brown bark. Some of the stems are dead with dark-gray lesions.

On the roots: Roots are creamy-white and look healthy. There is no odor coming from them. Some are dried and shriveled and have remained on the tree Figure 15—64 , while the majority have fallen to the ground.

There are some fruits with brown mushy spots on them. Are other plants in the landscape affected? This is widespread among the four peach trees. I also see some wild plums in the greenbelt behind my home with the same wrinkly, rotten fruit. Where is the damage seen on the plant? Is it evenly distributed around the tree or localized?

Inside the canopy or on the edges? High in the canopy or near the ground? The flowering and fruiting wood seems most affected, so the damage is on the outer edge of the canopy.

When did you notice this problem? A few fruits started looking like this two years ago. Last year the damage was on a few more fruits, and this year it is much worse.

You saw stink bugs and flies on the fruit, which are signs of a possible insect problem. They have piercing-sucking mouthparts. There was no stippling on the leaves or fruit to support these insects as the problem.

There is no evidence to support flies as the cause of damage to the tree. Because there were symptoms on the fruit—wrinkly brown or rotting spots—and because some stems were damaged with brown streaks inside the twig wood, you hypothesize this plant is suffering from a disease.

You discover the Extension publication Growing Peaches in North Carolina , which covers all the major diseases. From the signs and symptoms noted in the diagnostic steps, you determine that your peaches have brown rot Monilinia fructicola. You could send a sample to the NC State Plant Disease and Insect Clinic for a confirmation of diagnosis.

But after carefully reviewing the diagnostic steps, you are confident you have identified the problem. The poor cultural practices of never pruning, soil sampling, or removing shriveled and mummified fruit are the primary causes of the disease having spread. The dead limbs most likely died due to cankers forming and girdling the limbs.

The spores on the fruit and the mummified fruit being left on the tree or on the ground increased the pathogen, so that all of the trees now have brown rot. You also learned from Growing Peaches in North Carolina that the wild plums behind your home can also be a vector of the disease.

After researching brown rot, you learn that without proper sanitation, pruning, and chemical control, the disease can quickly reduce peach yields. Brown rot on the fruit is also unsightly, and the smell of rotting fruit is not the most appealing.

These trees provide shade in your backyard and, in previous years, provided a modest harvest of delicious peaches. You would like to save these trees, but also recognize that peach trees can struggle in North Carolina and they will always require a high level of maintenance.

You decide to try some management techniques for the next two years to see if the problem decreases. Physical —First, you clean up any mummified or rotten fruit left on the ground from previous years is cleaned up and disposed of off-site.

You maintain a pruning schedule to remove any diseased limbs in the spring, before bloom. You pick fruit regularly so that it does not become overripe before harvesting. You are sure to remove and discard off-site any fruit left over after the last harvest, including mummified fruits that are still hanging on the trees.

You consider talking to your homeowners association to see if it is possible to remove the wild plum trees, which are vectors of brown rot. Cultural management —You obtain a soil test and amend the soil according to the test results. You address the heavy clay soil by applying a 3-inch layer of organic mulch around the trees every fall.

You maintain a proper irrigation schedule, making sure the trees receive at least 1 inch of water per week during the dry period. Chemical management —There are several fungicides to manage brown rot; they must be applied at a timely interval because the infection can start when trees are in bloom.

If conditions are dry between fruit set and ripening, brown rot is not usually a problem. If there is rain, apply fungicide at the first sign of fruit color development.

This is usually around three weeks before harvest. It is also important to remember to rotate fungicides to reduce resistance. Keeping a garden journal or notes about the management strategies tried and their results will help make future decisions easier. Some of the management strategies may take time to produce results, and having a written record will help to jog your memory.

Your tree may not produce fruit for many reasons. Frost can also be a culprit. Flowers do not have to be in full bloom to be affected by frost. As soon as flower buds begin to swell, temperatures below 29°F cause the buds to turn black and die.

Lack of pollination also affects fruit production. Avoid spraying your trees during the day when pollinators are most active. Be sure you have planted any trees needed for cross-pollination. Finally, vigorously growing trees put more energy toward leaf, trunk, and root production than flower and fruit production.

Shoot growth on bearing fruit trees should average 12 inches to 18 inches a year. What causes trees to grow too vigorously? Over fertilization and over pruning. Heavy nitrogen application favors wood over flower growth. Fertilizing the grass or other plants surrounding the trees may affect fruit trees.

If you have not over fertilized you could be overpruning. Fruit trees need to be pruned each winter, but heavy heading cuts can cause a tree to produce leaves and branches instead of fruit. I have a large overgrown pear tree that does not produce very well.

How do I get it to fruit for me a g ain? Restorative pruning of a large fruit tree takes a few years and quite a bit of work.

For the first year or two, remove dead wood, suckers, water sprouts, or crossing branches. Next, make two to four cuts of major branches.

This helps decrease the height to a more manageable size and allows for better light penetration. Last year I had a ton of apples and this year not nearly as many. Is there something wrong with my tree? Many apple trees have a natural biennial cycle of alternate bearing habits.

They produce more fruit in one year and less the next. Years with heavy fruit set signal to the tree to have a subsequent year with lighter fruit. This is mitigated by thinning the fruit in years with heavy fruit set three weeks after the fruit has set. Childers, Norman F. Modern Fruit Science.

Determining how much nitrogen to use is not always easy. The nitrogen needs of an orchard will be higher with young trees filling space, large crop years, and stone fruits.

Any suggested rates in this chapter are just starting points and will need to be modified through observations and data from your own orchard blocks. All nitrogen fertilizers must convert to the nitrate form of nitrogen in the soil for the majority of uptake by the tree. Some ammonium can be taken up directly by the tree.

Thus, the different choices of fertilizers can vary in how long they take after application to be available to the tree. The most commonly recommended ground nitrogen fertilizers used are urea and ammonium sulphate that can take up to 3 weeks to convert for tree uptake, especially in cool springs.

Ammonium sulphate is more acidifying than the other fertilizers. Ammonium nitrate is the old standard, but only available through limited controlled locations, requires ID, and is an expensive form of nitrogen.

Ammonia urea sulphate Calcium nitrate Calcium ammonium nitrate CAN is half calcium nitrate quick uptake and half ammonium can take 3 weeks to convert with no acidifying effect.

Nitrate and urea forms of nitrogen are more easily leached out of the soil than ammonium forms however, ammonium will readily convert to nitrate under optimum pH and aerobic conditions.

It may be spread evenly over the orchard floor in orchards with closer-spaced smaller trees, however, fertilizer rates should be adjusted to match the total area of application. Spread fertilizer a day or two after a full irrigation set, then irrigate for only 2 hours following application to help move the fertilizer just into the root zone of the trees.

Urea fertilizer left sitting on the surface of the ground in warm weather can lose nitrogen to the air through volatilization. Rates and Frequencies of First-Year N Soil Broadcast Applications. First soil application recommended soon after planting.

Most nitrogen fertilizers especially Nitrate forms are highly soluble and are washed from the root zone with frequent and over irrigation. Fertigation Rates and Timings for First-Year Plantings. Commence applications at post-bloom when finished phosphorus applications.

These fertilizer rates compensate for the inefficiency of nitrogen uptake from sandy soils where irrigation can leach nitrogen below the root zone. Recent research has indicated in an orchard with a sandy loam soil and irrigation controlled by atmometer based scheduling that production and quality of apples could be sustained by application of a total of g nitrogen per tree, applied during any 4 week period.

If high density planted trees have failed to adequately fruit after first year, continue first year nutrition program. If vigour has been low, also investigate possibility of another nutrient deficiency leaf analysis or inadequate first year irrigation.

If vegetative vigour is excessive, reduce nitrogen application rates by to ½. Mature producing trees are considered to be those capable, due to size, of carrying 30 to 50 bins of fruit per acre. Reduce the suggested nutrient schedule if mature trees that are capable of carrying a full crop, have experienced a frost or event that results in a significantly lighter crop.

Smaller trees that must still grow to achieve a structure that fills the tree spacing and are older than 3 to 4 years may be carrying too heavy a crop for the tree size.

These weaker trees should receive the start of their nutrient schedule after bloom and should not have rates cut with the removal of crop load. In all apples, too much nitrogen can lead to poor fruit colour especially in heavy crop years , soft fruit, poor storage quality, increased bitter pit issues, crown and root rot of apples.

There can be varietal differences in nitrogen requirements. For example, Honeycrisp is especially sensitive to balance tree needs compared to fruit needs. The fruit requires low levels of nitrogen as long as growth is adequate pruning and crop load management seems to encourage adequate growth as fruit size and quality is easily negatively affected.

Factors such as fruit size, block colouring, crop load, susceptibility to bitter pit and maturity dates may influence the amount of nitrogen needed in a given block.

Growers should plan to make adjustments to their nitrogen rates based upon these and other influencing factors. Some of the rich silt soils may require very little, if any, nitrogen for mature producing trees for a number of years in a row. Vegetative growth, leaf nitrogen analysis, fruit size and fruit colour development must be used to adjust rates of application.

These nitrogen recommendations are guidelines only! There is no substitute for careful observation. As mentioned above, the rate will depend upon tree growth, commodity, and fruit quality.

The lower rates are for apples growing in good soil compared to the higher rates for peaches growing in sandy soil. As a good balance between cropping and vegetative growth is achieved, less nitrogen per kg of fruit is used.

Good consistently cropped trees have proportionately less vegetative extension growth. There is less demand for calcium, i. a better leaf to fruit ratio. High leaf to fruit ratios, that is lots of vegetative growth and a light crop, particularly under low humidity, creates a stronger leaf demand for calcium away from the fruit.

Large fruit size with a small crop will also contribute to a calcium dilution in the fruit. Too much or too little growth, as well as leaf analysis results provides the information needed to help adjust the required nitrogen rates for the following season.

Measure leading terminals growing outwards at an angle of 45 degrees around the outside of the tree and take an average of these measurements.

Increase, reduce or eliminate the quantity of nitrogen fertilizer to achieve the correct amount of terminal growth as shown in the following table:.

Nitrogen must be in good supply as reserves in the tree for developing flowers and fruitlets. In apples, excess nitrogen is one of the main contributors to poor fruit colour and poor fruit quality. In cherries, it has been suggested in studies from Michigan that a ratio of 5 leaves: 1 cherry is ideal for sizing quality fruit.

Previous season nutrient applications can have a big impact on spring reserves in the current season. Nitrogen applied over the winter and spring up to flowering encourages strong vegetative growth.

If there are concerns, nitrogen applications can be delayed until immediately after bloom to allow for adjustments to match crop load. In all fruit trees, heavy cropped trees may also need additional nitrogen foliar spray after harvest, or before harvest in late maturing apple varieties.

Regular leaf analysis is strongly recommended to assist in determining nitrogen requirements. IMPORTANT: None of the foliar mineral element sprays should be applied with emulsions or oils.

Foliar applications of urea: To avoid delayed maturity of fruit, do not apply urea later than 45 days before harvest on apples or pears or later than 21 days on stone fruit.

Use of foliar urea on pears may aggravate fire blight. A dilute spray see page , at rates ranging from 1. Caution is necessary, however, as foliage injury and excessive fruit removal can occur when this material is applied. Some growers concentrate spray more at the tops of trees where the nutrient is needed more.

Apply under good drying conditions. Cultivars differ in their sensitivity to ATS. Application of ATS is not suggested for varieties such as Braeburn and Sunrise that have low fruit set tendencies as excessive fruit removal may occur.

Jonagold, Gala, and Empire are sensitive to rates above 1. Spartan, Fuji, Delicious, Golden Delicious, and McIntosh have benefited from rates up to 1. When applying, use eye protection, a respirator, rubber gloves and protective clothing. Young non-bearing trees with poor growth 2 sprays 2 weeks apart.

Bearing trees more than one spray may be required. Soil sampling is not a reliable method for assessing available phosphorus levels for application decisions.

Plant tissue samples are a more accurate method to assess phosphorus needs by the trees. The adequate level in leaves of mature apple and stone fruit trees is 0. A leaf phosphorus concentration range of 0.

Recent research has indicated that early flowering in apples is promoted by high phosphorus nutrition in the first year. High leaf P in year 1 increases the number of flower clusters the second year for apples on M. Foliar phosphorus applications are used during the cell division period of the fruit following petal-fall to help with fruit quality and sizing potential.

A few studies found Phosphorus used within 6-weeks of apple harvest may help boost apples already developing colour, however, results can be variable. Fruit exposure to the sun will still give the highest colour results compared to any fertilizer treatment.

Most newly transplanted trees benefit from the addition of a soil phosphorus treatment to ensure available phosphorus in the soil for improved root development. Years of replant bioassays in apples by Dr. John Slykhuis, showed phosphorus and then fumigation treatments as having the most consistent significant effect on positive root growth.

Phosphorus is more efficiently utilized when applications are incorporated near the developing roots by mixing into the soil of the planting hole or percolated into the main root zone as dissolved phosphorus in irrigation water.

Ammonium phosphate fertilizers are the most common choices for phosphorus fertilizers with replants because high phosphorus availability has been observed when they are applied in the root zone. The most used ammonium phosphates are the granular monoammonium phosphate or the soluble Rock phosphate and triple superphosphate are granular forms, which are less soluble and are less available to trees when surface broadcast.

Liquid formulations suitable for fertigation include ammonium polyphosphate or phosphoric acid With any incorporated granulars or composts, make sure the fertilizer is mixed well with planting hole soil or peat mixtures.

Reduce rate by half on extremely coarse textured gravelly soils to avoid root burning. NOTE: Prior to planting new trees in old orchard soils, read the last paragraph under LIME and the section on APPLE REPLANT PROBLEM.

WARNING: Phosphite based fertilizers are NOT a source of phosphorus to the tree. Phosphites are used to help move whichever nutrient is attached to it into the plant. Phosphorous Applications for all Tree Fruit. Can seriously burn roots and must be well mixed into the planting hole or trench.

Do not do a full irrigation for a week after application to avoid washing nutrients past root zone. Very low burn risk. Commonly Available Soil P Fertilizers in BC. Phosphorus is an important element in root growth. The use of liquid and soluble granular products are generally more efficient than granular recommendations used in the planting hole, therefore rates are lower for phosphorus than those for planting hole application.

Use caution if mixing more than one nutrient in fertigation as phosphate fertilizers can be incompatible with some magnesium or calcium fertilizers resulting in precipitates that plug emitters.

Check irrigation water calcium Ca , magnesium Mg and bicarbonate HCO 3 concentrations. According to information from Ontario, to avoid phosphate precipitates, Ca and Mg combined levels should be less than 50 ppm and HCO 3 less than ppm. Phosphorus demands of mature fruiting trees usually declines so annual soil phosphorus fertilizer may not be required.

Monitor leaf and fruit concentrations to ensure adequate phosphorus nutrition. Recent research has indicated that applications of 20 g P 2 O 5 per tree as ammonium polyphosphate annually at bloom would be advantageous for apples receiving adequate applications of nitrogen, potassium and boron.

Potassium is an important major element in tree growth and function, however, deficiency is not a common disorder in British Columbia. Potassium deficiency has been shown to be more common in high density fertigated orchards, especially when drip irrigated.

The deficiencies usually develop in sandy, coarse textured soils and show up as trees begin heavy fruit production usually third year. It is characterized by reddish brown leaf scorch symptoms.

Symptoms appear when leaf potassium is below 0. The majority of orchards in British Columbia show leaf tests above the adequate level of 1.

Potassium deficiency is less common in lower density orchards with sprinkler irrigation but has been reported when soil potassium levels are low.

Some studies have shown an improvement of fruit colour when potassium nutrition moves from deficient to adequate levels See production guide leaf analysis levels , but too much potassium can be a problem.

Unnecessary application of potassium to tree fruits may interfere with uptake of calcium and magnesium. Calcium is especially important for the prevention of bitter pit and breakdown in apples and preventing Anjou pit in pears. Magnesium is important in preventing leaf scorch and premature dropping in apples.

N-K fertigation should be considered for high density orchards on sandy soil especially when drip irrigated. The following rates can commence in the first year and then be adjusted upwards or downwards depending on K concentration in subsequent years.

This soil test level is used to ensure sulphur adequacy for all crops grown in British Columbia. Ensuring immediate adequacy can be realized at little or no cost by using a fertilizer that contains sulphate-sulphur as a secondary nutrient; for example, ammonium sulphate ; Epsom salts magnesium sulphate ; potassium sulphate ; gypsum calcium sulphate and other fertilizers.

On calcareous soils those with a pH above 7 using when applying nitrogen fertilizer will ensure sulphate adequacy. However, this fertilizer should not be used on acid soils See Soil Acidification.

Zinc is important in trees for the formation and function of chlorophyll, several enzymes, and the growth hormone auxin.

Foliar analysis results indicate low zinc levels in interior orchards, particularly in apples, cherries, and pears. This is due to sandy soils with pH levels above 7.

Zinc does not move readily within the plant due to translocation problems. It is common for leaf zinc concentrations to remain low, even after application of recommended dormant zinc sprays. Use the early dormant spray timing if planning on using leaf analysis in the summer to monitor zinc levels.

Zinc deficiency symptoms such as chlorosis, blind bud, rosetting and little leaf can, however, be reduced by such applications. For apples it is recommended that zinc sulphate be applied annually at silver tip to green tip stage of bud development stages 2 and 3 , supplemented by one or more sprays of chelated foliar formulations of zinc during the growing season.

It is not recommended to use chelated products, such as Zintrac, mixed in with the dormant oil sprays as a replacement to zinc sulphate applications. Chelated products are designed for best absorption when applied directly to leaves. Two zinc sulphate sprays are recommended for cherries; the first during the late dormant period up to bud swell stage stage 2.

Do not mix with the dormant oil spray. The second spray can be applied within 2 weeks after harvest. Chelated zinc products can also be used during the growing season to help supplement zinc, but should never fully replace the dormant zinc sulphate spray. For pears, an annual application of zinc sulphate is usually adequate.

Apply at green tip stage stage 3 before dormant oil. For other kinds of fruit trees showing low zinc levels, a zinc sulphate application at late dormant stage should be applied annually. Suggested Range of Leaf Leels for Zinc Zinc - ppm. Foliar Zinc Applications. Zinc sulphate spray for all tree fruits - to be used when foliar analysis indicates low zinc levels.

Soil acidification can occur in orchards from the use of nitrogen fertilizers. Soil acidification can be accelerated by applying acidifying fertilizers through drip irrigation see table below. The rate at which a soil becomes acidified depends on the type of soil.

A sandy soil becomes acid more quickly than a clay soil. High lime or organic matter content in a soil slows the acidification process. Sensitivity to soil potential acidification can be identified through a quick test that determines the Acidification Resistance Index ARI.

This index is calculated from standard soil test data soil pH and exchangeable Ca, Mg, K, Na. The results of the quick test and recommendations are available from your soil test laboratory. There are three categories of soils:. ARI very sensitive.

ARI moderately sensitive. Acidification can be prevented by using fertilizers that do not contain either ammonium or urea. Soils that are already acidified should be limed to at least pH 6. After several years of drip irrigation, the nutrient content of soil beneath drip irrigation emitters may change.

Soil sampling to determine soil boron, potassium and salinity is a desirable strategy to prevent nutrient deficiencies or excesses from developing.

Comparison of a composite soil sample see soil sampling section collected directly beneath emitters to samples collected from alleyways would provide a measure of changes which may have occurred in specific orchards or orchard blocks.

Recent research indicated that orchards frequently have very low leaf boron and zinc concentrations and occasionally low leaf magnesium and potassium levels.

Regular leaf sampling and analysis will alert the grower to emerging problems and is an excellent strategy to track the nutritional health of orchard blocks.

Equivalent Acidity of Commonly Applied Fertilizers. From Western. Note: There are also various N sources containing multiple nutrients. These forms of N are usually more expensive sources of N but are advantageous under situations where other nutrient deficiencies occur as indicated by leaf, soil or fruit analysis.

Where soils have become acidic below pH 6 , poor tree growth and certain disorders, such as bark measles on Red Delicious or Fuji, may result. Lime may be applied to raise soil pH levels. Most virgin soils in the British Columbia Interior are neutral or alkaline i.

However, the use of most nitrogen fertilizers and continued irrigation in orchards for many years favours the development of acidic conditions which are caused by the leaching of calcium and magnesium.

Low pH levels are most likely to appear in coarser soils and are often restricted to areas within the driplines of trees, where fertilizers have been applied. The need for liming must be determined by measuring soil pH. The quantities of limestone to be applied to achieve pH 6.

The lime prescribed by a soil test is assumed to have a neutralizing value of calcium carbonate equivalent. Rates for other materials must be adjusted according to their calcium carbonate equivalent.

Lime which has been used in CA storage and dolomite lime may be applied at the liming rate recommended for calcium carbonate.

However, CA lime must be applied in a pulverized fine condition to obtain effectiveness equal to ground limestone. Dolomite lime, in addition to alleviating soil acidity, is valuable for supplying magnesium which is commonly deficient to McIntosh, Spartan and Newtown apples.

Lime can be applied at any time of year, except that one month should be allowed between application of fertilizer and application of lime to avoid loss of ammonia nitrogen to the air. Also, one month should be allowed between soil-applied boron and application of lime. Spring and summer applications of hydrated lime require care be taken to avoid deposits on foliage and fruit, which can suffer burning.

Lime must be broadcast evenly over areas in which the pH is low pH 6. These will usually be areas where fertilizer has been spread year after year.

Areas of an orchard in which soil tests show pH levels above 6. Shallow cultivation after application will aid in the absorption of lime. However, shallow cultivation can also damage tree roots, outweighing any advantage to cultivating in the lime.

Limed soils begin to re-acidify from the surface upon reapplication of the commonly used nitrogen fertilizers urea, ammonium nitrate and ammonium sulphate. Regular pH monitoring of the surface layer 10 cm will indicate when there is a need to reapply. Before planting trees, soil samples should be taken at cm depth.

If the soil pH is below 6. Lime should be applied at a rate to bring the soil pH to 6. Otherwise the pH could drop below 5. This chapter has been prepared in the spirit of encouraging effective use of high quality compost to improve the long term sustainability of fruit production in interior BC.

Not all compost is the same, and raw manure is not compost. Enhancing soil organic matter is critical for sustaining orchard productivity, particularly for orchards on coarse-textured soils with low organic matter contents.

Enhancing soil organic matter has multiple benefits that all contribute to improved root growth. For orchardists, the most effective means of enhancing soil organic matter is through the addition of compost to the root zone, either through incorporation into trenches or planting holes before replanting, or through surface application to established plantings.

Composts are distinct from manures and other organic wastes: It is very difficult to use manures and some other non-composted organic wastes as soil amendments without injuring crops and having negative impacts on environmental quality. Such materials can burn roots salt stress, ammonia, organic acids , and surface application can increase the prevalence of fecal bacterial contaminants in the orchard environment which in-turn increases the probability of fruit contamination.

How is compost distinct? Compost is stabilized earthy matter having the properties and structure of humus or native soil organic matter that is beneficial to plant growth when used as a soil amendment.

Compost is produced by actively managing the decomposition of large quantities of fresh organic matter. The first phase of composting involves intense microbial activity as the most easily decomposed parts of the organic matter sugars, starches, proteins are quickly metabolized.

In most cases, this phase generates heat and the material reaches temperatures in excess of 50 C, which kills fecal bacteria, plant pathogens, insects and most weed seeds. This property of stability is important because the application of non-composted organic materials to soil in relatively large quantities can stimulate undesirable flushes in soil microbial activity resulting in the immobilization of nutrients and production of organic acids that are detrimental to root health.

In the case of organic wastes with high nitrogen contents, such as poultry manure, high application rates can also generate toxic levels of ammonia in the soil.

Compost can be produced from a wide variety of initial feedstocks, including manures, prunings, municipal yard trimming, kitchen wastes from municipal greenbin collection programs, food processing wastes, old or spoiled hay, and wood wastes. Growers can obtain finished compost from commercial and municipal composting operations.

Composts can also be made on-farm. The requirements of OMRR ensure that the material has passed through a thermal phase adequate to kill-off fecal bacteria, and that the finished compost is stable, i. The requirements of OMRR also include limits for heavy metals that are set to prevent their accumulation to problematic levels with long-term repeated compost application.

Collectively, the requirements of OMRR ensure that the compost is generally safe for the environment and stable. Some municipal composts include biosolids or municipal sewage sludge as a feedstock. Such composts can be very high quality and meet OMRR specifications for environmental safety.

It should be noted, however, that guidelines for organic production and some food safety certification programs such as CanadaGAP prohibit the use of compost made with biosolids as a feedstock. On-farm production of compost: For growers in the Okanagan and Similkameen, poultry manure from the Fraser Valley is a common source of feedstock for making compost.

Using inadequately or improperly composted poultry manure is not substantially different from using fresh poultry manure. As described above, such materials can burn roots salt stress, ammonia, organic acids , and surface application can increase the prevalence of fecal bacterial contaminants in the orchard environment.

Growers attempting to produce on-farm compost from poultry manure should be familiar with how to compost properly. A list of suppliers of composts and manures for composting:. Bighorn Contracting Ltd.

Phone GlenGrow, City of Kelowna. Wholesale quantities of GlenGrow are available at the Glenmore landfill, North Glenmore Road. Phone compost info line Ogogrow contains biosolids , City of Kelowna.

Wholesale quantities of Ogogrow are available at the Regional Compost Facility, Commonage Road. Superior Peat Inc.

includes bark mulches and composts , Carmi Avenue, Penticton Phone Corfe Farm. Wholesale quantities of poultry manure compost, delivery available. Southern Plus Feed Lot.

It is important to note that chemical properties can vary substantially between composts made with the same feedstocks, and even among batches of compost made at the same place out of the same feedstocks. Regardless of whether composts are obtained from commercial suppliers or made on-farm, they should be analyzed before use.

The influences that composts have on soil and tree growth are affected by how they are applied as well as their properties. See Soil and Tissue Testing Labs page 9. Typically, very little of this N is immediately available to the crop as occurs with chemical fertilizers, but becomes available in the long term as the organic material decomposes and interacts with soil N.

Consequently, composts should be considered as soil amendments rather than N fertilizers. Nonetheless, they will affect soil N availability. This can occur for composted dairy solids. Total P and K contents: As with N, the P and K in compost is not as readily available as it is in fertilizers.

In contrast to N, however, less is known about factors governing the availability of P and K in composts. Electroconductivity EC : The EC of compost is a critical property reflecting the salinity of applied materials.

It is possible to utilize high EC amendments, but care must be taken to avoid direct contact with roots or the material must be sufficiently diluted with low EC soil to prevent root burn.

In general, surface application is safer than mixing compost into root zone soil when EC is a concern. Composts are generally mixed into soil in planting holes or trenches before replanting or surface-applied as a mulch.

The following are general guidelines for commonly used rates. Maintenance rate - 4 tons per acre covered 4 tonnes per hectare or approximately 10 yards. In response to trees showing decline — 12 tons per acre covered 12 tonnes per hectare.

Root examination before and after application is recommended and may indicate when additional applications are necessary. Compost is generally spread by shovel off a trailer. In this case the compost should be spread evenly in the herbicide strip.

The application rate can be estimated by weighing a 20 litre bucket, spreading the contents evenly in a 10 sq. This gives a visual indication of the rate. For example, a 20 litre bucket full of compost zinc sulphate container should cover the 4 ft.

herbicide strip of 2 ½ trees on a 1 ft. Biochar: Biochar is an amendment which has received recent publicity due to its perceived environmental benefits which include the potential to stabilize and elevate the carbon content of soil at the same time providing the benefits associated with increasing organic matter content.

It is produced by the incomplete combustion of organic material such as forestry waste wood under low oxygen conditions and is often a by-product of its use for energy production.

There are several BC companies actively researching its production. At present there is considerable variability in its composition and limited research on its benefits for use in perennial horticultural production systems.

Humic materials: Commercial formulations of humic acid or humate solid form of humic acid are being marketed as growth-promoting soil amendments. These materials are extracted from ancient decomposed plant material in the form of leonardite or lignite soft forms of coal.

Their nutrient contents can be low but formulations can be supplemented by the addition of nutrients. They also have high cation-exchange capacities. The effects of these materials on fruit tree growth have not been studied adequately to support any recommendations.

A phosphorus amended humic material improved initial growth of grape in half the plantings when tested in local vineyards. Liquid organics: There are several liquid organics available and suitable for application with irrigation water, but there have been few comparisons of their effectiveness.

Compost teas are from the leachate produced by aerated or anaerobic no oxygen digestion of manures and have been advocated for insect and disease control and as nutrient supplements. There is limited documentation of their effectiveness under field conditions.

Vermicomposts: Composting carried out via earthworms does not include a high temperature incubation period since temperatures above 35 C kill earthworms.

Commercially available vermicomposts will have had to meet requirements of OMRR with respect to pathogen reduction. Acceptance of vermicomposts can be greater than that of composts because of better visual aspect, high nutrient content and microbiologic activity but there is limited documented proof of superior performance relative to other composts from replicated field trials.

Over the past 20 years a wide range of field experiments have been conducted in grower and government research station orchards to test the effectiveness of increased application of organic matter applied either as surface mulches or amendments incorporated into the soil profile.

The experiments have been conducted in high-density apple orchards on dwarfing rootstocks and involved randomized and replicated comparisons of treatments carried out for years. The number of sites where increased use of organic matter improved orchard performance primarily increased tree yield is summarized in Table 1.

It is important to note that about half of the trials with incorporated amendments were with compost. In one orchard it was found that surface mulching and amendment incorporation buffered against water stress and associated reductions in fruit size which occurred from accidental failure in the irrigation system.

Summary of number of orchards exhibiting improved performance in multi-year experiments conducted over the past 20 years by PARC-Summerland in grower and research high density apple orchards on dwarfing rootstocks.

From this data it can be concluded that use of surface mulches has generally been more effective than incorporation of amendments and that benefits have not always been observed. In the course of experimentation it was discovered that organic amendments may not result in improved growth of trees on sites with fertile soils or with strong fertigation programs suggesting that for these sites there was no measurable effect on tree performance by the addition of compost.

However, as previously noted, compost can be used to promote long term improvements in soil quality and nutrient reserves. Although use of composts can improve soil moisture regimes this is not a substitute for proper and timely irrigation.

For example high frequency irrigation four times daily with small volumes of water could be more effective than surface mulching on a very coarse loamy sand soil.

Also over-irrigation resulting in excessive leaching of nitrogen mineralized from compost could negate the benefits of using composts. Compost is not a substitute for fertilizer programs.

Routine soil and leaf analysis are still recommended in order to maintain nutrient balance in tree fruit blocks. Growers are encouraged to discuss their plans for composting with their field person or with the BC Ministry Extension Service.

Organic application could be ineffective when an important limitation such as replant disease or a nutrient deficiency such as potassium was unaffected by the treatment. Although beneficial, the grower should not rely on composts to overcome severe replant disease or nutrient deficiency which can often be diagnosed by soil analyses or a plant pot test at the time of planting.

As previously indicated compost with a high salt content can inhibit plant growth particularly if concentrated around bare roots. BC Tree Fruit Production Guide. Currently Viewing: Fruit Tree Nutrition. Fruit Tree Nutrition Monitoring and Assessing the Nutrient Needs of the Orchard Proper balanced nutrition is important in all crops; however, knowing what the right nutrient needed at the right time for the right reasons with the right product can be very different between commodities, orchards, and seasons.

Leaf Analysis Leaf analysis is currently the best available method of determining nutrient status of most minerals in fruit trees. Leaf Sampling Methods for Orchards What to sample : A sample is a composite sample of leaves from multiple trees within a similarly comparable block within the orchard and should not represent more than 10 acres.

Fruitlet Mineral Analysis Like soil and leaf analysis, fruitlet analysis can be a valuable tool when making decisions about feeding programs in apple orchards.

Optimum 'Ambrosia' fruitlet mineral values and ratios for samples collected six weeks before anticipated harvest. Soil Analysis Soil analysis is mostly used to determine the soil acidity or alkalinity pH , the level of soil salts as electrical conductivity EC , and boron. Soil Sampling Methods for Orchards When to sample: Soil sampling is typically done in the fall or spring.

How to sample: a Soil probes see below , augers, or shovels can be used to take samples. c Take a 2. g Fill out a soil information sheet for each sample.

h Draw a rough sketch of the orchard indicating the various sampling locations. com BC Tree Fruits Cooperative Quality Development Lab Winfield, BC Can test soil pH and conduct replant bioassays bioassay tests require minimum 4 months for results.

com MB Laboratores Ltd. com Pacific Soil Analysis Inc. net Apple Leaf Drop Apple leaf drop is sometimes diagnosed as a disease or sometimes as a nutrient deficiency.

Application Methods of Mineral Elements All fruit trees in the British Columbia Interior require applications of mineral elements in addition to nitrogen. Fertigation has several advantages: Transport of nutrients directly to the root zone so that fertilizer amounts and timing can be precise.

Reductions in the amount of fertilizer applied relative to standard broadcast application. Less excess nutrients will therefore be available to be leached and pollute the groundwater. Fertigation cautions: Drip irrigation system must be well designed to provide uniform water distribution System must be maintained regularly to prevent plugged emitters.

To ensure that fertilizer is uniformly distributed regardless of the irrigation system layout: Begin fertilizer injections after the system operating pressure has stabilized following turn-on; and Allow 30 minutes of flushing with water after injection has been completed prior to switching to the next zone or turning the system off.

Such procedures are especially important if injections are infrequently made i. Mineral Nutrients Boron B Boron is important for pollen tube growth and thus, is needed at bloom to aid fruit set. Apply only when soil or leaf levels of boron are low.

Granubor Fertilizer Borate Granular Calcium Ca Calcium is very important for the building of strong cells in the fruit, new shoots, and roots.

Bitter Pit of Apple, Cork Spot Anjou Pit and Alfalfa Greening of Pears Bitter pit on apples shows as small pits that resemble miniature bruises. Suggested Range of Leaf Levels for Calcium Leaf Type Low Adequate High Apples 1. Reduce nitrogen application to moderate tree vigour.

Do not over or under irrigate in the spring. Lime when soil pH is low. Use bees to ensure good pollination for crop load and full seed set for drawing calcium to fruit 6.

Do not apply excessive amounts of potassium in the spring. Chemical For Apples — There are several foliar calcium products to choose from. Compatibility of Calcium Chloride with Pesticides 1. Ca Sprays in Rain to Prevent Cherry Cracking This application may not always work and is based on research using overhead irrigation application.

Collect a representative symptomatic sample that fully describes the observed problem. The entire plant may be needed for the most accurate diagnosis.

This is especially important with vascular and root rot pathogens. It is important to look at roots and lower stem to have whole picture of the problem. Digging out the plant helps to preserve the integrity of the root system.

Submit a generous amount of plant material. If the plants are small i. seedlings , send several plants. Samples from different plant species should be bagged separately and labeled.

A mixture of living tissue and necrotic tissue is needed to isolate the pathogen and diagnose the disease. Do not send dried or dead plants Leaf or Stem Tissue Samples: place the sample in a zip-seal bag as soon as it is collected.

Do not use paper bags. Fruit Samples: Separate fruit i. berries, apples, peaches samples from roots and top growth material.
