How to properly prune apple trees?
In order for the apple tree to bring tasty and healthy fruits every year, it is necessary to prune it. This procedure is quite significant for the correct formation of the crown of the tree. Not all experienced gardeners know how to prune apple trees. The optimal version of the crown of the tree should have the longest branches from below, which gradually become shorter upwards. It is worth considering in more detail the goals of pruning an apple tree, its timing, as well as some secrets from professionals.
The need for a procedure
The apple tree belongs to fairly resistant trees, so it grows in almost every summer cottage.
Tree pruning is necessary to achieve the following goals:
- allows you to correctly form the crown of a young tree, the age of which varies from 5 to 7 years, and also influences the formation of the future crop;
- provides the most comfortable crown lighting and contributes to the nutrition of an adult tree;
- regardless of age, sanitary pruning allows you to get rid of branches affected by various diseases.
The main task of pruning apple trees is to thin the crown and ensure an excellent harvest. If you trim the crown correctly, then the tree will receive not only the necessary illumination, but also ventilation. In order for an apple tree to bear fruit well, these two requirements should be followed.
It is worth noting that if the branches are located correctly, it will be easier for the gardener to pick apples. Old trees are pruned for rejuvenation, because the old branches no longer bear fruit and do not carry any value. When the old branches are removed, young branches will begin to appear in their place, which in the future will bring a rich harvest.
Pruning a tree is a rather important stage in the dynamics of the development of an apple tree. There are several varieties of it, so you first need to clearly define its purpose, and after that choose the best option for creating a strong and healthy tree. The timing and scheme of its implementation directly depend on the type of trimming chosen. Experienced summer residents are aware that circumcision should be performed several times throughout the year. Of great importance are the climatic conditions in which the apple tree grows. But also the pruning process itself should be done correctly, adhering to a specific algorithm.
Pruning of apple trees is usually carried out in the following periods:
- spring - carried out in early spring, even before the appearance of buds: it is produced to increase the fertility of the tree;
- summer - used to rejuvenate the apple tree, while sharp objects are not used; it includes pinching shoots, bending, breaking out and others;
- autumn - carried out only after the tree throws off all the foliage.
You should not blindly adhere to the above types of pruning of an apple tree, since the varietal affiliation of a tree plays a huge role; it is imperative to take into account the individual characteristics of the plant. Nevertheless, you should familiarize yourself in detail with the various types of pruning of this fruit tree.
spring
The first pruning of the apple tree is precisely the spring one, which is done even before the buds swell on the apple tree.
An interesting fact is that some experienced gardeners cut the branches of the tree even in winter, since the apple tree is a frost-resistant horticultural crop.
- To begin with, all frozen and dried branches should be removed, since in the future the tree will expend its strength on their restoration, which is meaningless, because the branches after frostbite no longer bear fruit.
- Next, it is worth clearing the tree from annual shoots. With normal fruiting, young branches are superfluous, since they take away nutrients, but do not bring a crop. The presence of young branches negatively affects the formation of the fruit set.
- The rest of the branches are trimmed depending on their height. It is worth adhering to the following rule: the higher the branch, the more eyes it should have. If a tall apple tree is pruned, then after spring pruning, no more than 8 buds should remain on it. If we consider dwarf varieties, then their number should not exceed three eyes.
The correct crown of an apple tree consists of three tiers. If their number is greater, then in the future there may be difficulties in harvesting.
The spring crown should consist of the following tiers:
- three main branches are involved in the formation of the first tier;
- four main branches create a second tier;
- two frame outlets provide the third tier.
Important! Five-year-old apple trees require shortening of the main trunk. This option is optimal for apple trees. Such a crown is called a longline.
Summer
Few gardeners resort to pruning apple trees in the summer.But experienced summer residents strongly recommend not to forget to trim the branches at this time, since it is carried out both for preventive and sanitary purposes. It will protect the tree from various diseases, pests and increase its fruiting. In summer, the main goal is to adjust the crown of the apple tree. When the tree is covered with foliage, it is perfectly clear which branches are superfluous, spoiling the appearance of the apple tree, and also produce crown shading. In this situation, it is worth both completely removing such branches and cutting them to obtain the required length.
It is in summer that young shoots form on the trees. If you do not touch them, then during this period they begin to actively grow. To prevent this, it is worth pinching them. This procedure will significantly slow down their growth for two weeks. In addition to pinching, many gardeners resort to breaking out branches that are superfluous. Summer pruning is usually done with bare hands, since gardening tools do not need to be used to clean the tree. Only to remove the tops that grow vertically, thereby thickening the crown of the tree, you will need to take a saw and a pruner.
If you do not make summer pruning of the apple tree, then in a few years the young shoots will become quite strong branches, and in the future you will have to clean up healthy, formed branches, which will stimulate the growth of young shoots. In this case, the gardener will have to make more time and effort to give the tree the right shape and form a good crown. Many summer residents recommend removing them at the initial stage of sprout formation.
autumn
A rather important stage in the development of an apple tree is the cleaning of a tree in the fall from old and damaged branches. It is made after the apple tree throws off all the foliage. Its main purpose is to carefully prepare the plant for wintering. To do this, it is worth removing all old and depleted branches. It should be noted that all autumn work on cleaning the tree should be carried out even before the first frosts, so there is no need to delay it, because otherwise the risk of frostbite on fresh cuts increases, which may fester in the future.
In order to properly prune an apple tree in the fall, it is worth adhering to a certain algorithm for performing work.
- First you should deal with the strongest and largest branches that are damaged. Quite often, a branch cracks from a large number of apples. In winter, the damaged branch is likely to freeze, for this reason it is better to remove it in the fall.
- It is very important to thin out the crown of the tree before winter sleep. In places where there are many branches, it is worth clearing the weak ones, while leaving only straight and strong branches.
- Next, it is worth eliminating such bends that grow at the wrong angle. Usually, with strong gusts of wind and heavy rainfall, they break quite quickly, so it is worth removing them before winter.
- Removed branches must be burned, and fresh cuts must be treated with special septic tanks to protect the tree from the possibility of infection.
Timing
When determining the timing for pruning an apple tree, it is worth starting from the climatic features of a particular region. Even experienced gardeners cannot accurately determine the date of pruning of an apple tree.Therefore, weather conditions must be taken into account. Pruning in the spring must be done one month, in extreme cases - three weeks before the start of sap flow. Experts point out that before this time you should not get down to work, because after a cold winter, the wood of the tree is characterized by fragility. If you clean the crown before the set time, then this can cause irreparable harm to the plant. It is worth trying to pick up the time when the tree has already "woke up" from hibernation, but the formation of buds has not yet begun.
Pruning schemes
The pruning scheme should be determined for each apple tree individually. You should take into account the size and age of the tree, its location on the site, what trees grow nearby, what amount of work needs to be done. To date, there are several schemes for pruning apple trees. It is worth noting that there are no strict norms and requirements for this process. They should be used as a basis, and the choice is up to the gardener. Only he can decide what is necessary for the apple tree, given the overall situation.
Among the most popular pruning schemes, it is worth highlighting the crown of the following forms:
- round;
- curly;
- columnar;
- flat vertical;
- flat horizontal;
- pyramidal.
Spring pruning is essential for apple trees as it prepares the tree for the new fruiting season. During this period, it is necessary to do sanitary pruning for young apple trees, which allows you to form the correct crown.
This process includes the following steps:
- first you should remove all frostbitten, dried and damaged branches;
- it is necessary to completely eliminate the branches that are infected with various diseases or have suffered from pests;
- all branches should be removed that grow towards the inside of the crown, and also form an acute angle to the trunk;
- to rejuvenate old branches, it is enough to cut them.
If necessary, adjusting trimming is carried out. With its help, you can influence future fruiting.
If the tree gave a lot of fruit in the previous year, then you can not resort to spring pruning. With a low yield, the tree needs a strong cleaning of old and diseased branches, which will allow you to leave a sufficient amount of fruit so that the tree does not spend a lot of effort on them.
Summer pruning is insignificant, but if the tree is sick, then you should not wait for autumn, it is better to clean the diseased branches immediately.
So, during the summer period, the apple tree needs the following care:
- with the advent of summer, all diseased branches that have not been removed already during spring cleaning should be eliminated;
- at the end of June, it is necessary to pinch all fast-growing green shoots, which will prevent crown shading, as they will no longer take up nutrients;
- in the summer, it is also necessary to monitor the condition of all branches: cracked or broken branches must be removed;
- already at the end of summer, old branches should be cleaned, on which a small number of apples are presented, and branches that obscure the crown of the tree should be removed;
- and it is also very important to cut fruit-bearing branches at the end of summer, which will allow you to postpone the start of the growing season next year.
If in the summer the apple tree does not have damaged branches, then it is only necessary to eliminate those branches that form the crown, since it should not be very dense.It is summer pruning that guarantees a good harvest.
It is quite important to clean the apple tree in the autumn, since during this period it is possible to carry out any work for which there was not enough time in the spring or summer.
When the harvest is already harvested, you should pay attention to the following steps:
- you need to cut off all the branches broken under the influence of the wind;
- those branches that cracked or broke under the heavy weight of the crop should be eliminated;
- sanitary pruning allows you to eliminate all diseased branches that have suffered from a large crop;
- at this point, you can clean old apple trees to rejuvenate them;
- it is also necessary to eliminate the branches on which during the fruiting period there was a minimum number of apples;
- pruning also lends itself to those branches on which deformed or small-sized fruits are presented;
- all branches that create a shadow for healthy, fruitful shoots should be removed;
- it is worth cleaning the tree from those branches that have been affected by various diseases and pests.
Important! It is not possible to single out one pruning scheme for all trees. Each pruning will be unique, because it is worth considering the individual needs of each tree.
When choosing a pruning scheme, it is worth considering the age of the apple tree. The main task in cleaning a young tree is to create the right basis for the correct development of the crown. An old tree should be cleared of old branches before fruiting, as this will affect the future harvest, and also provide the tree with vitality. Mature plants need pruning in order to protect them from various diseases and pests. Usually, the types and methods of pruning trees are the same for both young and adult apple trees, but the technologies are different.It is worth considering each option in more detail.
Annual
Pruning is done to achieve two main goals:
- keep the height of the main shoot so that the main branches develop on the sides;
- form a stem.
Pruning to form a crown can be done only one year after planting the tree. An annual plant usually has a central stem and two or three branches. The height of the center conductor must not exceed one meter. Very long skeletal branches must be shortened; while they should be twenty centimeters shorter than the height of the tree. Three to five buds should remain on one branch.
To achieve the correct bole, all shoots that are located on the trunk up to half a meter above the soil should be eliminated. Those branches that form an angle of 60 degrees at the point of growth should also be removed, as they will spoil the correctness of the crown. Some gardeners try to give them a horizontal orientation.
If you manage to change their direction, then there is no need to remove them.
Biennial
In order to properly clean the apple tree for the second year, it should be guided by the fact that this procedure should help lay the foundations for the correct formation of the main tiers of the main branches. The apple crown can be given any shape, but the cupped shape should be avoided. Each tier should have about 2-5 large branches. Between levels, a distance of 40 to 60 cm should be maintained. Usually this distance depends directly on the height of the tree.
Branches should be spaced approximately equally apart; in this case, it is worth starting from the circumference of the central stem. A two-year-old apple tree needs to shorten the branches of the skeleton.If you want to create a cup-like crown, then it is in the second year of plant development that it is necessary to remove the central trunk, in the future the crown will be formed without a central conductor. A cut should be made, but only above the first fork of the branches. Since there is no central trunk, you should push off from the side branches. Usually there should be from two to four trunks, their number depends on how many branches are located on the first tier. Thus, the crown should be formed before the age of 5.
adult
The apple tree is an adult tree after reaching 5 years of age. From this point on, the main pruning produces a rejuvenating effect, but it should be done only after sanitary cleaning.
When rejuvenating pruning, you should pay attention to the following actions:
- you need to remove old branches that no longer bear fruit or bring small, tasteless fruits;
- eliminate some of the tops;
- cross branches should be cut into a ring;
- remove the lower branches, which differ in direction inside the crown;
- it is worth clearing the trunk of overgrowth, both basal and growing near the trunk;
- be sure to shorten the main trunk; it should be borne in mind that the height of an adult apple tree can vary from two to three meters.
Pruning the top of the apple tree is important because it allows you to increase the quantity and improve the quality of the fruit. Apple trees that are over 8 years old need to be pruned to rejuvenate them a few times a little bit.
If a tree immediately loses a large amount of vegetative mass, then this will be a huge stress for him. It is worth dividing the plan over the next few years.
crown formation
The correct formation of the crown of a tree is directly dependent on the quality of the pruning of a young apple tree. This is an important factor that affects further fruiting.
Today, many experienced gardeners for apple trees choose the following types of crowns:
- sparse-tiered;
- medium standard;
- fusiform;
- combined.
For beginner gardeners, it is better to give preference to a crown of a sparse-tiered type. To create it, only 5 main shoots should be left, the distance between which should be in the range from 35 to 40 centimeters. All remaining shoots need to be destroyed. An excellent choice would be a medium-standard type of crown, since it is also characterized by simplicity. It is necessary to cut down all the branches that are located at a height of 0.80 to 1 m from the ground. The rest of the shoots remain intact.
When choosing the time to form the crown of a young tree, it is worth giving preference to early spring. It is recommended to perform all actions even before the growing season, that is, before the appearance of the kidneys.
When the tree is two years old, it is worth cleaning again from excess shoots, while leaving only 4-5 of the strongest on each branch. They must grow at a right angle in order to form a beautiful crown in the future. During this period, it is worth pinching the growth point. It should be located higher than five buds from all other branches. After this, 2–3 years, the apple tree should not be touched so as not to disrupt fruiting, although dried and damaged branches need to be removed. Do not forget to follow the shape of the crown - you will need to shorten the overgrown branches in order to maintain a rounded shape.
Adult apple trees, as well as heavily neglected ones, should be cut only in autumn. First, you should get rid of damaged and dry branches, then remove those branches that grow inside the crown or interfere with the growth of young shoots. Do not leave barren branches of large sizes. They do not bring a crop, but draw out a lot of useful substances. Those skeletal branches that interfere with harvesting or grow in the other direction should also be cut off. For an old apple tree, it is very important to open the crown, which can be achieved by shortening the central trunk; while its height should not be more than three meters from the ground.
Rejuvenation of an old tree
In order to improve the health of an old tree, it is imperative to renew it by removing old branches; it should be borne in mind that the skeletal branches of the tree must be strong and healthy, otherwise cleaning the tree will not give positive results. Rejuvenation of an old tree should be carried out over several years, including several stages. The most favorable is spring pruning, as the tree quickly recovers. Even before the foliage appears, you can perfectly consider the shape of the tree and build a plan for future crown adjustments.
Important! If the old tree is sick, then the choice is up to each gardener. There are two ways out of this situation: cure the apple tree and then prune it or cut it off and plant a new one.
In the first year, large branches should be eliminated: it is necessary to remove all diseased, bare (without bark), dry, deformed, and also intertwined. In the second and third year, it is worth forming the center of the crown; in this case, the top of the main trunk should be cut off, its height should not be higher than 2.5 meters.It is necessary to remove the tops left after the previous pruning, however, you can leave a few vertically growing branches, which will later give new shoots.
Old apple trees are rarely updated, but the thickening of the crown has a great influence on the condition of the tree, so it is also worth keeping an eye on. Crown formation is recommended to be done no more than once every two years. It is worth removing shoots and branches that do not let the sun's rays through to fruitful branches. All broken and dried branches also require removal.
If the apple tree has always given large yields, but recently its fruiting has declined sharply, then it is definitely worth cleaning the branches that do not yield. This pruning is called anti-aging. In general, about a third of the total number of tree branches is removed. Be careful not to cut out more than necessary. Of course, after such a procedure, the tree will not be able to bring a rich harvest in the first year.
To rejuvenate the apple tree, this procedure should be repeated for another two years. It must be produced every spring, at about the same time, although weather conditions are decisive in choosing a date. Such spring pruning will allow you to start the main renewing processes, to “wake up” the vital resources of the apple tree.
Pruning a columnar apple tree
The main goal is that the crown of the tree should be similar in shape to a column, so it is worth paying due attention to the elimination of side branches. In addition, it is worth cutting off all unnecessary shoots and branches, which lead to a thickened crown of the apple tree. The main rule is that when pruning a columnar apple tree, it is forbidden to touch the main trunk.An exception is possible only if the tree has stopped growing: it is only necessary to shorten the central trunk a little. The spiny tree must have an intact apical bud.
The central shoot of a young columnar apple tree should be strengthened using special supports. This approach will protect the main trunk from strong gusts of wind and other adverse weather conditions. At the beginning of spring, even before the buds appear, the side branches should be pruned, leaving only two buds, from which young shoots will form in the future. A year later, also in spring, all the branches that grow vertically should be shortened again, leaving only two buds each - this will contribute to the growth of new shoots. At the same time, you should not do anything with horizontal branches, because they will bear fruit this year. Next spring, all fruit-bearing branches of the horizontal direction must be cut so that a ring forms.
Important! Pruning "on the ring" needs an even and clean cut of the branch, while the bark must remain intact, without any disturbance to its surface. There should be no knots or stumps left. The place of the cut must be covered with garden pitch.
dwarf apple tree
The dwarf apple tree also needs timely pruning for proper crown formation and a rich harvest in the future. The main goal is to help in the expansion of the tree, while excluding its development in height. It is worth paying attention that at first seedlings of a dwarf apple tree grow quite quickly. Only with the beginning of fruiting, its growth begins to slow down.
To make the fruits tasty and large, it is worth pruning the tree as follows:
- an annual apple tree in spring must be cut so that its height does not exceed 50 cm from the ground; the cut must be treated with garden pitch;
- a year later, in the spring, you need to pay attention to the side branches - they need to be shortened to the second bud, and also do not forget about the central trunk - it should be shortened by about 1/4;
- in the following spring, it is necessary to completely eliminate all branches that are aimed at growing in the middle of the crown or down, while the central trunk, like the side branches, should be shortened by 20 cm; all actions should be aimed at forming a rounded crown of small size.
Important! It is worth forming the crown of a dwarf apple tree in the first two or three years after its planting, but it is necessary to take into account its development rate. Mature trees that bear fruit need regular sanitization, which should be done every spring and autumn.
Helpful Hints
Experienced gardeners pay attention that after pruning, the apple tree needs special care - it is imperative to water and feed. After spring pruning, it is worth fertilizing the soil around the tree with those fertilizers that include potassium, nitrogen, phosphorus; it is better that they are in equal proportions. If you need to feed the tree after its autumn cleaning, then it is worth choosing fertilizers containing phosphorus and potassium, because it is these components that contribute to the rapid healing of wounds, and also have a beneficial effect on the bark of the tree. It is very important to strictly adhere to the time of fertilization. Their number should be in moderation, since an excess of top dressing will do more harm.
Important! Nitrogen fertilizers should not be used after the autumn pruning of the apple tree, since this component contributes to the development of young shoots that will not have time to get stronger by winter, which will negatively affect the general condition of the apple tree.
The following rules of experienced gardeners should be considered when pruning an apple tree:
- the tree should be no more than five meters high; at a higher height, its branches do not receive the right amount of nutrients;
- certain varieties of apple trees have fruit-bearing peripheral branches only, which further leads to their injury under the heavy weight of the fruit; to exclude this, you should regularly prune the side branches that bear fruit;
- forming crown pruning should be stopped if the tree has stopped producing apples; to change the direction of growth of branches, it is worth using rope extensions.
When pruning apple trees, you will need special tools, such as saws, garden shears, secateurs, loppers, and others. They must be very sharp and disinfected. After pruning diseased branches, be sure to decontaminate the tool before moving on to healthy branches. Branches should be cut as close to the trunk as possible, which will avoid the formation of knots and stumps. If you need to remove a large diameter branch, you should first shorten it, and only then make a full cut.
If a saw is used to cut branches, it is worth making an incision only from below, because this will allow you not to injure the bark. Next, cutting is done from above. All places of cuts must be treated with garden pitch. Some gardeners use oil paint. Processing should be carried out on the second day.
The use of nitro-paints or enamel products should be avoided. And the main thing to remember is that apple trees need annual pruning.
