Pruning apple trees in the fall - everything a novice gardener needs to know
For gardeners, pruning apple trees in the fall is a great opportunity not only to tidy up your garden, but also to "unload" spring chores. In the spring, there are already a lot of things to do: you need to spray trees from pests, and to prevent diseases, process and feed. And if the garden is large, you should also have time to cut it before the buds bloom. In order not to have to rush, it is better to postpone this procedure until autumn. An autumn shearing of an apple tree is well tolerated if you meet the deadline. Moreover, it contributes to the improvement of tree nutrition, forms and “unloads” the crown, which improves productivity indicators.
However, it is important not only to prune the apple trees on time, but also to do it right. Do not forget that the general development of garden residents also depends on this. To make trees grow strong, less often were sick and gave a bountiful and large harvest, you need to know how to cut them. What the pruning will be will determine the appearance and age of the plant. If young cultures need shaping pruning, then adult “ancient” specimens require anti-aging procedures. What is their difference and when is the right time for autumn pruning - this is what we will be talking about today.
Time for pruning apple trees in autumn
It is difficult to name the exact timing of pruning, because they depend on the climate and will be different in each growing region. On average, this is the month of October. The main rule: before frost must be at least 2 weeks in stock. This time is enough for the apple trees to tighten the cuts. You can focus on the leaves. As soon as they start to fall, it means that the trees have stopped growing and it's time to start pruning them.
At the same time, in northern latitudes, it is more expedient to postpone the procedure to spring. The autumn period is short there, winter often comes suddenly, and persistent disadvantages are immediately established. Apple trees simply do not have time to heal the wounds, and they will freeze.
Types of autumn pruning
There are several types of garden pruning, including apple trees, depending on its goals, the age of the trees and the degree of shortening of the shoots.
Based on what goal is in front of you and in what condition the garden is, pruning apple trees in the fall can be:
- sanitary (removal of dry and thickening branches);
- formative (especially important for young trees);
- anti-aging (helps to "give a second life" to old apple trees).
In addition, pruning involves not only removing the shoots completely, but also shortening them. From how strong it will be, pruning happens:
- Weak (1/4 of the branches are cut off). It is used for crown formation in young apple trees up to 5 years old.
- Medium (the shoot is shortened by 1/3). Used to regulate crown loading in mature trees.
- Strong (1/2 of the shoot length is removed). It is the main "tool" for rejuvenating old apple trees.
Let's consider each type of procedure in detail.
Pruning apple trees in the fall - the basic principles of sanitary measures
There are general pruning rules that determine which shoots should be completely removed. They must be guided not only during the autumn, but also when performing the spring garden haircut. They are also the purpose of sanitizing trees.
So, when starting to sanitize pruning, do not miss and completely cut these branches:
- affected by the disease;
- dry;
- growing vertically downward (directed towards the ground);
- extending deep into the crown and thickening it);
- rubbing against each other (remove one, leaving a more beautifully formed and strong one);
- young shoots that appear almost at the very ground, below the grafting site, are wild;
- spinning tops are thin straight branches growing vertically upward or slightly to the side.
If the branch of the apple tree is dry or partially affected by the fungus, it is allowed to leave its healthy part. If this is the case, trim the shoot back to healthy or live wood.
And the shoots are wild, and the tops draw juices from the apple tree. They thicken the crown, reduce yield and disease resistance. Therefore, such branches are subject to mandatory deletion. But with tops, there may be an exception. When the apple tree has withered or “degenerated” only one branch, you can replace it with a young top.
How to rejuvenate an old branch with a spinning top
Over time, on old branches of apple trees appear spinning tops, while the shoot on which they grow can be both healthy and dying. In the latter case, there is no point in leaving the disappearing branch. It is more expedient to rejuvenate it at the expense of the most developed young top, turning the latter into a fruiting branch. It is best to do this in the fall, and then in 2 years you can see the first harvest.
Partial rejuvenation of the crown through tops is carried out in this way:
- On the old branch, select the most developed and thickest top, and completely remove the rest.
- Shorten the left shoot by 1/3.
- In spring, a young twig will branch out laterally. These are future fruit shoots. Do not touch them, but shorten the top of the former top again. It is desirable that the side branches are directed towards the old one, which is being replaced. If they also grow vertically, you can do this: bend the branches by force. Place them in the desired position and secure with a rope.
- The next year, you can remove the dry branch.
Rejuvenating pruning of old apple trees
Apple trees actively develop and bear fruit abundantly on all branches up to 20 years of age, then they need rejuvenation. If this is not done, then the fruits will be tied only at the top. In this case, the tree itself becomes too tall, which makes it difficult to care for it in terms of the same pruning and harvesting. Rejuvenation is recommended no more than once every 5 years.
How to properly do anti-aging apple pruning:
- First of all, reduce the height of the tree, leaving no more than 3.5 m of the trunk (from the trunk) and cutting off everything that is higher.
- Shorten the skeletal branches. Select the nearest developed young shoot on them and cut off the old one immediately behind it.
- Remove the lowest branches hanging to the ground.
- Thin the crown: cut out improperly growing and thickening shoots. Remove excess branches above the young ones.
- Examine the tops, leave only those that grow from the trunk along the entire diameter of the crown. Cut the rest.
Too old and neglected apple trees cannot be rejuvenated and drastically pruned at one time. This is too much stress for the tree. It may not survive the intervention and dry out completely. Divide the procedure over 2 to 3 years, replacing no more than 3 large branches at a time each year.
Formative pruning of an apple tree in autumn
If you laid an apple orchard in the fall, then proceed to the formation crowns from seedlings can be immediately. In any case, this process is long and will last for a couple of years. Trees develop unevenly, at one level a couple of shoots may appear in one season and several more in the next.
Step-by-step pruning scheme
The formation of the crown of a young apple tree takes from 3 to 4 years, depending on how old the seedling you purchased. Usually the crown is made in 2 or 3 tiers. The more tiers, the taller the tree as a whole and the thicker its crown. This is inconvenient both in terms of care and for the apple tree itself. Too many branches require increased nutrition, which has the worst effect on the yield and durability of the tree.
For novice gardeners, information on how to form a crown step by step, from the year of planting until the culture reaches 4 years, will be very useful.
First year
If you purchased a one-year-old seedling, it will not have side branches yet, only one stem. Shorten this twig ¼ of its height in the fall. For the first year, that's all. If your seedling is already a couple of years old, and it has side shoots, go straight to the next step.
Second year
Next season, start laying the first, lower, tier of skeletal branches. It should be located at least 50 cm above ground level. Therefore, cut out all lateral shoots that appeared over the summer and growing below this value.
From the branches growing above, form 3 skeletal ones. Choose the strongest ones, growing in different directions and at an angle to the central stem no more than 55 °, and shorten them. On one tier, branches can be up to 15 cm from each other. Remove the rest of the shoots.
Sometimes it happens that the young growth does not want to "lie down" and grows almost vertically, like tops. Do not rush to remove it, because such shoots can be changed direction by bending them in the right direction. It is best to bend the branches in the spring, when sap flow begins - then they are more flexible.
Remember to shorten the growth point. It is simple to determine at what height to cut the top off: from the tip of the upper skeletal branch to the top there should be no more than 20 cm.
Third year
Continue to form the first tier of skeletal branches. They have already started branching. Shorten the branches by 1/3, "remove" the top of the main stem to stimulate the laying of the second tier.
Fourth year
Shorten the tops of the shoots from the first (lower) tier so that they do not go over the upper branches. If the apple tree has given a strong growth, thin out the branches. Remove 1/3 of the length of young shoots of the second (upper) tier so that lateral buds also awaken on them. Cut the center conductor to contain height growth.
The further purpose of pruning is regulatory. It should be weak, as the strong pruning of the branches will encourage young shoots to grow vertically. They will thicken the crown, reduce the yield and resistance of the tree to diseases and pests.
In addition, every 4 years, replace the fruiting branches with young ones so that the fruits are large and their number does not decrease.
Features of pruning dwarf apple trees
Studying how the pruning of an apple tree is carried out, it is worth dwelling separately on dwarf varieties. Despite their short stature, they give an excellent harvest. In some varieties, the size of the fruits is almost the same as the larger types of apple trees. But in order to maintain high yields, such trees need to be pruned annually. Moreover, it differs significantly from the procedure for ordinary apple trees:
- First of all, start pruning dwarf trees, especially for the purpose of rejuvenation, earlier. This should be done at the beginning of autumn. Due to the less developed root system, such apple trees "come to life" longer.
- The degree of pruning depends on how many roots the tree has grown. The more of them, the less you will need to shorten the branches (by 1/4). Conversely, if there are few roots, shorten more (by 1/3).
- Lay the first tier below, at a height of 30 cm instead of the accepted 50 cm.
- Second-order shoots should be located strictly in the outer part of the crown and not have sharp corners. In principle, this rule has remained unchanged.
- Shorten those branches that are not suitable for the formation of the second tier at a height of up to 30 cm from the trunk. After a year, they will overgrow with side branches, and a crown will form.
- Dwarf apple trees bear fruit for 4 years, after which they need rejuvenation. Be sure to remove the 3-year growth by cutting at the level of a strong second-order branch. She will replace the removed part in the future. Also shorten strong shoots.
Such a strong pruning of apple trees in the fall for dwarf varieties is only beneficial, unlike ordinary apple trees. With renewed vigor, the crown begins to grow rapidly, laying new branches. And although the number of fruits becomes smaller, the apples themselves grow larger.
Summing up, it should be noted that pruning apple trees in autumn plays an important role in gardening. It helps to reduce and correctly distribute the fruit load, which increases the quantity and quality of the crop. In addition, apple trees, rid of excess shoots, winter better and get sick less often.
