    If the bark has burst

    In January, with sharp fluctuations in day and night temperatures, the bark of fruit trees cracks, frost cracks may occur. They can be found by knocking on the trunk with a piece of wood: in those places where the bark has come off, the sound will be muffled. On a warm sunny day, they must be carefully cleaned, disinfected and covered with melted garden pitch. And when it dries up, apply a tight gauze strapping, cover with a film and leave until spring.

    The bark cracks on the trunks of 3-4-year-old apple and pear seedlings. Why?

      - You are probably overfeeding the plants with nitrogen. In this case, in fruit trees, wood grows at a faster rate than bark, and longitudinal cracks form. Stop feeding trees and limit summer watering. Clean the cracks with a sharp knife and cover with a thin layer of garden varnish.

    I noticed that a small section of the bark exfoliated at one place in a pear. Why did this happen?

      - The reasons can be very different, but the main one is sharp changes in night and day temperatures in the winter, due to which the crust loses its elasticity and cracks form. Water gets into them, which, freezing, expands and tears the bark.
      In clear, frosty weather, peel off the exfoliated bark area to healthy wood, treat it with a copper-containing preparation (Bordeaux liquid - 30 g per 1 liter of water) or systemic fungicide (Skor - according to the instructions) and cover the wound with garden var.
      In the future, to prevent the formation of cracks, do not overfeed plants with nitrogen fertilizers, treat the garden in time against diseases and pests.
      And for the prevention of sunburn in late autumn (and again in February), whitewash the branches and forks of skeletal branches.

    Black wounds were found on apple trees (2-3 per tree). Where the foci are older - there is no bark, the wood begins to deteriorate (see photo). What is it? How to fight ??

      - In the photo - the effects of winter sunburn. Fungal diseases, including ulcers of black cancer, begin to develop on the dying crust. A preventive measure against sunburn is well known - this is the late fall whitewash of boles. If the disease, as in your case, has already manifested itself, in early spring, clean the wounds to healthy wood, disinfect with a solution of copper sulfate (20-30 g per 1 liter of water), cover with garden varnish and tie a natural cloth for a year.

    Not the first time, then on one, then on another tree after leaf fall, leaves remain on the branches that can hang until mid-winter. What is this talking about?

      - This indicates that the apple tree did not have time to properly prepare for the winter. In severe frosts, the weakest part of the tree (tops of annual shoots, part of flower buds) can freeze. This often happens because an amateur gardener fed the garden with fertilizers, in particular nitrogen fertilizers (and this is not only about mineral fertilizers, but also about manure, bird droppings), especially if it was fertilized in the second half of summer.
      In general, at the end of leaf fall in the garden, it is necessary to eradicate pests and diseases - spray the crowns of trees and the soil under them with a solution of ammonium nitrate (1 kg per 10 l of water). After this treatment, the single remaining leaves on the branches will fall off. If you missed the spraying, and in November there were leaves in the crown, carefully tear them off.

      - Presumably from the photo - this is a frost hole, which usually occurs in severe frosts and due to sharp changes in day and night temperatures: the sun heats the trunk strongly from the south during the day, causing sap flow, and at night the temperature drops sharply, the water freezes, expands, as a result what happens longitudinal rupture of the cortex. Later it exfoliates from wood.

      What to do? Strip the wound with a sharp knife to healthy wood, treat with a solution of copper sulfate (30 g per 1 l of water), coat this place with garden varnish and wrap it tightly with a natural cloth. The wound should heal.
