When deciding how to cover up a saw cut on an apple tree, many gardeners are faced with the need to replace the garden pitch, but the search for alternative options is not always successful. However, there are small tricks that allow you to use the simplest and most affordable materials for these purposes. A detailed review will not only allow you to find out how to properly process a tree cut after pruning branches in the fall with improvised means, but will also save you from common mistakes.

Timing of processing slices

Cuts on apple trees are the result of agrotechnical measures aimed at crown formation or tree rejuvenation . Most often, such work affects old and dry branches, removed in spring, after wintering, as well as too active young growth. Formative crown pruning is most often performed in the fall, when the apple tree is already bearing fruit. But even after that, processing cannot be carried out immediately.

You must first wait until the cut dries up - several days are enough for this, and then start protecting the tree from possible infection or pest damage.

The choice of terms for processing largely depends on the season, the weather outside. For example, during the period of heavy rains, drying of the sections takes at least a week. Dry and sunny days allow you to start painting over after 1–2 days . In the summer, on small-diameter branches, healing often occurs without the intervention of a gardener at all. Such events are not held in winter. All damaged areas (with cracks, traces of teeth of animals) are covered with putty in the spring, when the average temperatures will be positive.

Funds overview

When choosing a tool that can be used to close up a saw cut on an apple tree in autumn or spring, it is important to take into account all factors. For example, thin branches up to 25 mm in diameter can be easily treated with a disinfectant . Such damage to the tree will heal after pruning on its own, very quickly. Another thing is if the area is extensive, you can see the trunk without bark in the place where it cracked. If the diameter of the saw cut reaches 30 mm or more, serious measures will also be needed.

The crack or cut will have to be processed more thoroughly, removing the rotten areas to healthy wood. Even a broken apple tree can be reanimated too.

In this case, you will have to cut off the damaged area. Remove the sawn-off branches, and then clean the damaged surface in the place where the branch broke off from roughness with a special knife. After that, it is better to immediately lubricate the surface with a disinfectant solution, and then leave to dry.

After the wound on the apple tree heals slightly, it can be treated with garden varnish or replaced with other available means. In this case, the processing should not affect the bark at the edges.

For spraying

First of all, damage to the trunk or crown of the apple tree must be disinfected in order to close the access to it for various infections.

Even small fresh sections must go through this processing stage.

The following formulations are the best choices

1. Bordeaux liquid . It is sold ready-made and has a bluish tint. It is applied to the wood surface with a brush.
2. Balms with fungicides . They are sold at garden shops. They have disinfecting and antifungal effects.
3. Potassium permanganate . An ordinary medicine is dissolved in 1 liter of warm water to a bright pink hue. A few grains will be enough to disinfect the slices.
4. Copper sulfate . To process apple slices, a solution of 50 g of this substance and 1 liter of warm water will be enough. It is poured into the lime "milk" in a thin stream. It is also prepared in advance. You will have to dilute 30 g of lime in 500 ml of water.

When working with any disinfecting compounds, safety precautions must be carefully observed . It is necessary to distribute the solution in a thin layer, with a brush, avoiding contact with the bark and healthy areas of the wood.

For smearing

After disinfecting the cut on the branches of the apple tree or lubricating cracks and other damage, you will need to wait until the surface dries. After that, you need to cover the affected area with a sealing compound. It will help close access to the cut for insect pests, fungal infections and other sources of danger. If such processing is not carried out in time, the branch may begin to dry due to the disruption of the movement of the juices inside.

The most common means for covering up damage on the trunks and branches of a tree is garden var

It consists of a fat base, wax and rosin, sold ready-made or created independently.

Each component in the garden varnish fulfills its tasks

1. The wax eliminates contact with air. The putty does not move outside the treated area.
2. Rosin creates intimate contact with the wood. It prevents the mixture from flowing off.
3. The fat keeps the putty from drying out. It can be replaced with oil, drying oil, if you prepare the product yourself.

Before processing the cut, the garden pitch must be heated. So it will acquire softness and plasticity. On the surface of a cut or crack, other wounds, garden pitch is applied with a spatula, forming a thin layer like a film.

If you break this rule, the lack of air exchange in this area will lead to rotting wood.

When self-cooking, all the ingredients are simply melted, then combined and slowly poured into a container of cold water . The thickened composition can be packed in an airtight container. For an additional disinfecting effect, wood ash is added to a self-prepared garden pitch.

If the finished product is not at hand, you can replace it with other formulations. The easiest way is to independently prepare the following types of solutions in the country.

1. Clay talker . It is prepared from mullein and clay in equal proportions, flavored with a small portion of hay or straw. The resulting mixture will only need to be diluted with water to the consistency of liquid sour cream. Then it is applied to the surface of the wound with a thin layer and dried. A simple chatterbox can be made on clay and sand in a 2: 1 ratio.
2. Cement putty . This recipe is pretty simple. The putty is prepared from fine-grained sand and cement in a ratio of 3 to 1; drying oil can be added for elasticity. It is most advisable to apply such a composition with a large area of the damaged area. Cement putty works well for dealing with large cracks in the trunk, especially when reinforced with a piece of burlap or cotton cloth.
3. Varnish or paint . Oil-based or emulsion-based formulations are suitable, but it is worth considering that such coatings will have to be updated annually. If a water-soluble paint is taken, you will need to repeat the processing procedure after each heavy rain. It is better to immediately take oil mixtures with drying oil for smearing, which can form a dense air-tight film.

These are the main options for compositions that can replace garden var when covering up wounds on apple trees . All of them are well tolerated by trees, do not create burns, and prevent decay of the trunk and branches after pruning.

Possible problems

Pruning trees, cracking the trunk or breaking branches under the influence of stress are just a few of the reasons for using garden varnish and similar compounds. But if the preparatory stage of processing went wrong, problems may arise in the future . In this case, a saw cut on an apple tree will not heal well, the branches will dry out.

It is necessary to carefully monitor the appearance of atypical symptoms in order to correct mistakes in time.

Among the most common complications after pruning are the following

1. Leakage of juice from a fresh cut . Usually, the problem manifests itself in the spring, if the formation of the crown or reorganization was carried out after the start of sap flow. In this case, the wound simply will not have time to heal. To correct the situation, smearing the cut with a mixture of a clay-based liquid talker with the addition of copper or iron sulfate will help.
2. Leakage of liquid from under the putty . This phenomenon can be observed on large cuts and cuts, already covered with all the necessary compounds. In this case, the broken tightness will have to be restored. For this, the garden pitch or other composition is completely cleaned, a disinfecting mixture is applied. The cut is dried and then sealed again.
3. Darkening or blackening of the treated area . Even small spots require immediate attention, as they may indicate that the apple tree has been infected with cancer or other dangerous infections. Treatment begins with cutting the tissue of the tree and stripping it to a live shoot. Then the affected area is covered with copper sulfate, dried, coated with garden varnish.
4. Rot formation . Usually, this phenomenon is the result of the introduction of spores of the tinder fungus into an open wound on a tree. Rot is completely cleaned off, cutting off the affected tissue, and examine. Further rescue is possible only if there is a hard and wet layer of wood below. It is disinfected, covered with a layer of garden varnish.
5. Exfoliation of the bark . If it was caused by mechanical damage (by rodents or under the influence of other factors), then such a site is thoroughly cleaned with a garden knife, disinfected with a solution of copper sulfate in a 3% concentration and covered over. If the lesion is large, a full dressing may be required.

Correctly carried out processing of cuts and cuts helps the apple tree to recover faster from damage . If the deadlines for the execution of work have been violated, the likelihood of subsequent leakage of juice, rotting or disease damage increases markedly. Risks can be minimized by carefully choosing the time for pruning, as well as following the recommended sequence of actions to protect the plant after it.
