Reasons for the appearance of a hollow in a tree:
- In time, unhealed wounds. Any damage to the bark must be treated with garden varnish or another preparation, otherwise fungi or other microorganisms may get into the wound, which will destroy the plant.
- Improper grafting or pruning can lead to hollow formation.
- Carpenter ants or termites and other pests can cause large wounds on trees by damaging the bark.
- Chills and sunburn are also very harmful to trees, especially young ones. It is necessary to whitewash them on time to protect them from excessive sunlight and frost.
- A broken branch can also be the cause of this trouble.
What time of year do you need to do hole filling?
The best time for this event is autumn. At this time, all metabolic processes in plants slow down. Therefore, wellness treatments will be more effective. But everything needs to be done before October, so that the filling materials are well frozen before the onset of the slushiest and coldest part of autumn.
If a hollow is found in the spring, you should not leave it unattended until autumn, as it can grow larger over the summer. After all, moisture and microorganisms get there, which soften the bark. You need to disinfect it and cover it with plastic wrap.
Sequencing:
- First of all, the hollow must be cleaned of dead wood. It is necessary to remove the dust with a metal brush or other tool and saturate the bark with an antiseptic. For this there are drugs "Septustin" and "Woody Healer". You can also use copper sulfate.
- Then the cavities of the small hollow are covered with wood varnish and left open. A drain is made at the bottom of the hole so that moisture does not stagnate in the hollow. Over time, it should overgrow.
- If the hollow is more than 6–8 cm in diameter, then it must be filled with wood corks and covered with garden pitch.
- Very large hollows are filled with small gravel, expanded clay or broken brick and covered with cement or epoxy.
- This should be done on a warm dry day so that the cement or other filling material dries well.
- After filling, you need to put on this place a bandage made of fabric, parchment or plastic film, which is fixed with twine or other available material.
The hollow weakens the tree. The damaged plant grows more slowly and bears less fruit. Therefore, carefully examine your green pets and help them in time so as not to lose them.
