Many fruit trees — including semidwarf varieties — can easily grow to 15 feet and taller. Anyone who has tried to manage one of these large trees in a backyard will instantly appreciate the value of small fruit trees: They require less space, are easy to care for, and produce fruit in manageable quantities. Growing compact trees allows you to tuck more varieties of fruit into corners of your property or a small orchard, and means you can choose those varieties by flavor and climate adaptability rather than by tree size. Nearly any standard and semidwarf tree — from pears, peaches and plums to apples and apricots — can be trained to stay much more compact. Keep this cycle in mind when wielding your shears. The first step to growing a small fruit tree is to make a hard heading cut a cut that removes the growing tip when planting.

The higher density-supported training systems now used by commercial growers are managed by the same principles of pruning used in the past.
Before embarking on a specific training system for high-density plantings, investigate specific techniques required for training and pruning that system. Numerous experiments show that pruning is a dwarfing process, that is, it reduces the total size of the tree. Leaves are the food-manufacturing organs of the tree. Cutting away a live branch, which if left would have borne leaves, reduces the output of the "factory", and the final result is a reduced bearing area.
Summer pruning has the greatest dwarfing effect. There is a certain deception in the effects of pruning, in that strong shoots with large leaves tend to rise just at the back of pruning cuts. This gives the impression of increased growth. Pruning reduces the number of growing points, thus stimulating an increase of growth at the remaining points. However, pruning, in proportion to its severity, reduces the total growth and the total leaf surface of the tree.
Invigorate trees when necessary with appropriate fertilizer use. The removal or cutting-back of the laterals of a branch reduces the growth of that branch.
Pruning has the direct effect of producing growth response in the immediate area in which the cut is made. Excessive pruning, by over-stimulating growth, causes loss of fruit colour, delayed fruit maturity, and growth of suckers and watersprouts. Excessive succulent growth increases the hazard of fire blight in apple and pear, canker in peach, and winter injury in all species. Because pruning tends to force the growth of long, succulent shoots that grow late in the season, manufactured food is not allowed to accumulate in sufficient quantities to cause the formation of fruit buds.
Consequently, the tree is kept in a juvenile or nonfruiting condition for a greater number of years. Young trees often grow very upright, and become so dense that the grower is tempted to thin-out the branches. It has been shown, however, that early fruit bearing will open out a tree much more effectively than pruning.
With the young tree, remember: light pruning, early bearing, a spreading tree Figure 1. Figure 1. Central-leader type of tree. There are 7 main branches distributed vertically and spiralled on the trunk and attached by wide, strong crotches. Make pruning wounds flush with the limbs to which the unwanted branches are attached. The exception to this rule is with peach. With peach use a collar cut rather than flush cuts. Wood healing is more rapid when the bark ridge at the base of larger limbs is not removed during a pruning cut.
Where one-year-old wood is being pruned, make the cut as close as possible to a bud to facilitate healing. This is particularly important with peach because canker may enter where healing is delayed. Where the crotch angle is less than 35 degrees the attachment will be weak because of the inclusion of bark.
The tissues in narrow crotches Figure 2 are slower to mature in the fall and may be injured by low temperatures, especially in test winters.
Narrow crotches are usually further weakened by water, ice, rot organisms and canker. Thus, remove limbs that make sharp angles early. This avoids possible loss of a large part of the tree later on due to breakage from weight of fruit. Figure 2. Structure of wide a and narrow b crotches.
The narrow crotch is structurally weak and contains a bark inclusion arrow , an entry point for insect or diseases modified from Cornell Agr. When new fruit trees are dug in the nursery, a large percentage of the finer root system is left behind during the process. The new tree that once had a balance of leaves to roots now develops more leaves than there is root system to sustain.
The resulting tree will be out of balance, resulting in poor growth. To overcome this problem, heavily prune all fruit trees at planting time before growth starts. Eliminate all branches below 60 cm. If the tree is tall enough, cut back the leader to about cm, and remove all shoots. With well developed trees or older trees having some limbs you wish to retain, you can cut these limbs back to 2 or 3 buds and retain growth in that area.
Totally remove limbs:. Consider the pruning at planting time and over the next 2 or 3 years as a training process. The final strength of the tree depends upon the wise selection of branches and your ability to maintain the proper balance between these branches.
Mistakes made in this formative period may mean weak trees and, in addition, the correction of errors may call for severe pruning in later years - the removal of considerable portions of the bearing area and the creation of large wounds subject to infection. It is critically important that you build a strong framework in the early years. The central leader training system is recommended for all fruit trees.
This tree "Christmas tree" form is conical in shape, with a wide base and a narrow top. During the early life of the fruit tree, keep this tree with judicious pruning. Some trees, particularly sour cherry, peach and Japanese plum, do not retain a dominant central leader for long. This is not a problem. The central leader tree at maturity consists of main scaffold branches distributed vertically and spirally around the trunk Figure 3 , and with the topmost branch leader well in the lead of the lower ones.
The vertical distance between limbs occupying the same quadrant of the tree will vary from cm depending on the ultimate size of the tree. Limbs too close together will result in excessive shading.
This weakens the limb and leads to poor fruit quality, reduced productivity and ultimately failure of the shaded limb. If the branch angles at the main trunk are sufficiently wide over 35 degrees , there will be no bark inclusions in the crotches, resulting in a strong tree. With many cultivars the central leader will slow in growth, making removal or heading unnecessary. Keeping the central leader in the early years encourages wider angles on the framework branches below it.
The central leader of dwarfed trees will be lost prematurely if allowed to fruit too soon. Figure 3. It is extremely important to build a strong framework in the early years. Training the Young Nonbearing Tree The less pruning during this period, the more quickly the tree comes into bearing. Consequently, once the main branches are selected, do minimal pruning until the tree is bearing. An early crop of fruit, besides bringing early financial returns, slows down vegetative growth and bends down the branches.
This aids in controlling the height of the tree, and opens up the tree to permit more light and better spray coverage. Guard against too-early fruiting of the central leader. Prune lightly in the third and fourth years, chiefly by thinning-out rather than heading-back. Generally avoid heading-back from the second year, until the trees are in heavy bearing.
Remove branches that form narrow crotches less than 35 degrees with the trunk. Eliminate branches that grow straight up or into the tree, those that are weak and drooping, and those that tend to cross or otherwise interfere with others. Six or 8 main branches are usually sufficient to build a good tree. With pear varieties susceptible to fire blight, and where fire blight is likely to be serious, prune especially lightly and leave more framework and secondary branches.
Most pruning is done when the trees are dormant, between the time when the leaves drop in late fall and when the buds begin to swell in early spring. The safest and best time is just before the buds swell. The most risky time is very late fall and early winter. Dormant pruning of peach and nectarine increases the risk of winter injury; prune during the bloom period.
In the orchard, start spring pruning early enough to be completed before the leaves appear. The risk of winter injury increases if pruning is begun too early.
Pruning followed by low temperatures means winter injury - not always seen but almost sure to be present. The amount of injury is directly related to the length of time between the pruning operation and the temperature drop; the shorter the time, the greater the injury. All pruning has a dwarfing effect, but dormant pruning produces the most new growth. If you want new vegetative growth, dormant pruning is the way to get it.
The harder the cutting, the greater is the response in new shoot growth. The response takes place in the area of the tree where the cuts are made. Most growers prefer not to prune peach and nectarine trees until the flower buds have advanced sufficiently to assess the flower winter survival. Delaying pruning much beyond shuck split may cause a serious loss of tree vigour.
Pruning has the greatest dwarfing effect in June and early July. If you wish to reduce vegetative growth and prevent shoots developing, this is the time to prune. But remember that early-summer pruning has a very dwarfing effect. It first dwarfs the root system, and then the whole tree. Pruning at this time of year has little or no effect on stimulating new vegetative growth. At the same time, it is not nearly so dwarfing as early-summer pruning. The root system is dwarfed somewhat but only moderately, as compared with the results of early-summer pruning.
The best time to prune apple trees is in late winter or very early spring before any new growth starts. The tree takes up a dormant state after shedding its leaves and before sprouting new buds. Pruning is best completed just before growth starts in the Spring as cuts will heal quickly, cuts made in early winter will be open and unprotected until growth resumes in late March so a possible entry point for disease which you will want to avoid. Dormant - A tree is in a dormant state in the Winter approx between November and February. At this time the leaves have fallen and the tree's energy is conserved in the roots, trunk and main branches.
Harness your fears and reach for the shears! If you follow these tips, you should quickly get familiar with this winter pruning procedure, and will get better.
Newly planted fruit trees benefit from pruning to direct tree growth. Pruning also encourages the development of sturdy trunks that create strong, well-placed limbs. As the fruit tree ages, it requires pruning to maintain tree size, remove any dead or diseased branches and reduce the canopy size to allow sunlight to the lower parts to the tree. Fruit trees should be pruned during their dormancy, which is in December, January and the first half of February in all mild winter regions. However, you should not prune while wood is frozen because frozen wood is brittle, so in regions with severe winters, wait until late in the winter to prune. There are several reasons why it is best to prune fruit trees during dormancy. When you prune dormant fruit trees, there are no leaves on the trees, making it easier to see what you are cutting.

Not sure when or how to prune your fruit trees?
Pruning is an important part of maintenance when you're growing deciduous trees in your landscape. Stone fruits peaches, plums, and nectarines , apples, pears, and persimmons should all be pruned during their dormant season to keep them healthy and productive. Once your trees reach maturity—usually about 3 years after planting—they should be pruned annually to enhance tree growth, reduce fruit thinning, and adjust crop load for the following season. Pruning creates strong branches and allows proper sunlight to enter the canopy. So when should you be pruning?
A: As we get into the fall and winter most gardeners start to think about pruning fruit trees. It is easier to see the branch structure of the tree as it is most visible when the leaves have fallen. The wintertime is considered the traditional time to prune deciduous trees. This is true for many shade and fruit trees, but for some fruit trees pruning mainly during the summer growing season is a good practice for keeping the tree size in check and avoiding disease problems. And pruning during the winter months can prove to be downright harmful for some types of fruit trees. Cherries, apricots and a few related species are particularly susceptible to fungal and bacterial canker diseases, including Eutypa dieback, Botryosphaeria canker, and bacterial canker. Pathogens can be spread by rain or tree wounds — such as pruning wounds — during wet weather; subsequent infections spread through the wood for several years and may eventually kill the tree. Trees infected with these diseases will see limbs, twigs or entire trees wilt and die suddenly in late spring or summer with the leaves still attached.

When is the best time to prune fruit trees? I would like to start pruning as soon as possible. The time of pruning varies with the fruit tree but generally most fruit trees are pruned during the winter months, beginning at leaf drop.
It is important to prune fruit trees each year to encourage a robust fruit crop. Winter in northern Utah is a good time for pruning because the leaves have dropped, granting clear access to the entire tree structure and allowing you to see any damage or disease. Some arborists prefer to prune closer to spring; however once the temperatures begin to rise and trees come to life, pruning may cause damage. Here are some practical tips for winter fruit-tree care. Most fruit trees require aggressive annual pruning to encourage fruit production. The growth of new wood is necessary for fruit to develop, and new wood will only grow when old wood is removed.
Knowing the best time to give them a trim can be more difficult as it depends on what kind of tree you have and how you want to control its growth. Tree pruning is a great way to control the size of your trees and help them grow healthy by clearing away all the dead branches and other clutter and debris that accumulates over an Edmonton or Leduc winter.
Jump to navigation. The hardest thing about pruning trees is getting up the courage to make the first cut. After that, each cut gets a little easier. The fact is, the second hardest thing about pruning is knowing when to stop. But both problems can be solved with a little knowledge of how pruning works and why it is good for our deciduous trees and especially good for our fruit trees. There are two main reasons for pruning. The first is to improve a tree's shape and size, and it is the purpose behind pruning of ornamental --and shade trees.
There are lots of ways to shape fruit trees depending on the priorities of the grower and the space available but pruning is not just about pretty forms. Pruning can help trees to fight off infections by allowing for good ventilation and should encourage your trees to produce more fruit. In a community orchard there are many factors that influence how we manage the trees, such as highlighting the beauty of fresh, local fruit; bringing life and vitality to parks and streets; and creating habitat for urban wildlife.
