It often happens that older apple trees eventually begin to produce less and less harvest. But, starting with their replacement, you make a big mistake: the risk is great that the young sapling will not take root, you have to wait for a more or less abundant fruiting for a long time, and you can never be sure that these will be for apples. At the same time, a properly conducted rejuvenating pruning of old apple trees can breathe new life into your garden, and you will enjoy wonderful and fragrant fruits for many more years.

How to start pruning old apple
You should always start pruning an old apple tree by carefully examining the tree and issuing the main verdict - save or delete.
Pruning of old apple trees is best done in the fall according to the following scheme:
- We start with the fact that we remove dried, damaged and diseased branches. Now, once again carefully inspect the crown and trunk and remove everything that hinders the growth of new shoots (some branches do not grow outwards, but inside the crown, you need to get rid of them).
- Autumn pruning is good because at this stage you can clearly see on which old branches the fruits no longer form and, accordingly, that you can safely remove.
- Now once again inspect the tree. Determine which of the remaining old branches overlap the growth of young, already formed, and carry out the appropriate cleaning.
- Next comes the turn of the crown. The height of the apple tree should be shortened at no more than three and a half meters and thin it in the center so that the young branches have room for active growth and at the same time all the branches that remain on the tree are equally well lit by the sun.
- Inspect the young twigs and remove shoots that go after the main branching.
- Now it's time to deal with the tops.
Features pruning of apple trees
Regular pruning is necessary for fruit trees at any age, it should begin literally from the next year after planting the seedling. However, the technology of this procedure as they grow older changes in a certain way.
From this point of view, every four to five years, adult apples should be radically rejuvenated. The procedure involves the removal of extra branches from the crown, so that the tree is well lit, and you should be guided by the following principle: if you have a choice, it is better to leave more young branches than one old one. “Under the knife”, of course, we let dry, bare and uncomfortable growing (interfering with others) branches first of all. Old branches in the lower part of the apple tree, which began to sag, we remove to branching, from where the new escape has come from the right angle.
If necessary, such a rejuvenating pruning can be done in two stages (in the autumn of this and next year): in the first stage, we deal only with old branches, at the second stage - with young and tops. In addition to rejuvenating, so-called regulatory pruning of old apple trees is also important, which is carried out both in autumn and spring. This procedure is necessary for trees that are fully formed and have already begun to produce a large number of apples. In order for the tree to cope with the load, and the fruits were beautiful, large and healthy, in the spring you need to thoroughly thin the flowers, leaving as much as the tree is able to “feed”.
Pruning an old running apple tree
But what if the apple tree for many years no one was engaged, and it grows, how can? Here, of course, to work hard.
- We are preparing for the fact that it will not be possible to manage with a single pruning: you will need to deal with wood constantly, cutting it in spring and autumn. A running apple tree needs both rejuvenating and regulating pruning in order to start forming a sufficient number of fruit bearing branches;
- it is better to do the first pruning in early spring, before the start of sap flow, simply by removing dead and damaged branches;
- adjust the number of flower buds, as described above;
- It’s a mistake to immediately make a small tree out of a large tree: such a radical intervention can destroy an apple tree, as it becomes less protected before low temperatures and various fungal infections.
Ways to prune old apple trees
There are several ways to rejuvenate pruning of an old apple tree, each has its own pros and cons.
First of all, it is necessary to distinguish two main methods of trimming - shortening (trimming) and thinning (slicing). In the first case, the length of all branches more or less drastically decreases, in the second one branches are removed completely, others are left, as a result, the tree is better lit and ventilated.
First option primitively simple: every two years we cut all branches without exception into a meter or two (depending on the growth of the apple tree). The advantage of this method is that it is suitable for newcomers who do not understand agricultural technology, since you do not need to delve into the formation of a tree and choose which branch to cut and which branch to leave. But there is a serious drawback. The fact is that the fruits on the old apple trees are formed mainly on the tops of the branches, which just go under pruning. And considering the possible size of an old tree, the process may take several years, and all this time you will have to do without apples, moreover, and after the end of pruning, the tree will take more than one year to restore the yield!
Second option - radical: once cut the tree across the crown by one third. The advantage is that the procedure is not delayed for many years, but the minus, as mentioned above, is a high risk of the tree dying from frost or disease.For this reason, many gardeners categorically do not recommend acting in this way.
Third option involves the gradual removal of old branches, on which no fruit is formed. We choose such branches in advance and cut one or two this year, a couple more next, and so on. Thus, in a few years we get a rejuvenated and thinned apple tree, without causing much harm to it. Fourth option suitable for those who understand agricultural technology. If your tree has almost stopped its growth, we cut off the skeletal and fruiting branches on the three-, four-year, and in very old apple trees - at the ten-year level. Young branches shortened by half.
We repeat the procedure in the next section only after new fruit-bearing branches are not formed on the trimmed part of the apple tree, and they do not start producing a steady harvest. Will have to wait at least four years! At this stage, we limit ourselves to removing the tops that appeared after the initial pruning (branches that grew at the right angle, while leaving), and also slightly shorten the branches on the already cut part of the tree so that it does not overgrow again. Then, following the same pattern, we gradually prune the entire apple tree in a circle. At the same time, we rejuvenate the roots in the same area of the tree. To do this, stepping away a couple of meters from the trunk, you need to dig a trench 0.7-0.8 m deep along the entire length of the cut part of the apple tree. All root processes that are bare are cut (for this you can use a saw or a sharp shovel). Then it is recommended to clean the most powerful "stumps" with a knife, so they will start up young branches more quickly. After this, a fertile mixture is laid in the trench.
To prepare it, the same part of the compost or humus mixed with mineral fertilizers and wood ash is added to the soil dug out of the pit.Now on the trimmed part of the tree, young branches will begin to form with a vengeance.
After such pruning, the harvest on the unshorn part of the tree increases radically, and the apples grow larger and tastier.
Useful tips
When pruning an old apple tree, follow these tips:
- make sure that the tree can be saved (if necessary, consult with a specialist);
- if the tree is ill, it has damaged bark, hollows, etc. - it must first be cured and then rejuvenated;
- As a general rule, pruning should be carried out when the tree is at rest, but with respect to the apple tree, if we are not talking about cardinal cutting, but only removing the tops, you can pull up to the formation of buds;
- sick, broken and dried branches can and should be removed immediately, at any time of the season, here delay can only harm the tree, and such branches are completely removed, at the base;
- first, larger branches are cut, then smaller ones, and, as already mentioned, it is better to leave several young branches than one old branch (the less cuts, the better!);
- twisted and growing inward branches - under the knife;
- if possible, it is better not to cut the branches too thick, since the wound opening at the same time is open doors for infection;
- the cutting places must be properly processed: we clean the cut with a knife and cover it with garden pitch, it can be purchased at any store for gardeners or at a specialized department in the supermarket).It is possible to use a mixture of paraffin, ceresin and oil (petrolatum) for processing the slices, but not paint! Spil from thick branches, in addition, before the onset of autumn we wrap a dark film (you can use the trash bag). So it will be easier for the tree to recover;
- young shoots that appear after pruning should be thinned, leaving those that grow at an angle to the trunk, no more than one per every 0.7 m of area, the rest are removed, allowing them to first grow about 10 cm.
