The main danger of cracks is that infections and harmful mushrooms easily penetrate through the damaged bark, which gradually destroy wood. A strong gust of wind or a small load on the branch when harvesting ripened fruits will be enough so that the tree breaks.
“Therefore, it is important not to ignore even small cracks and not postpone treatment,” the article says.
Why cracks appear
Often the reason may be Inaccurate use of the lawn mower When caring for a lawn and then deep wounds are formed at the site of cuts on the barrel.
A serious threat also poses abundant cropwhen the branches do not cope with the severity of ripened fruits and can break, especially in places of departure from the barrel. Particularly vulnerable areas where branches grow at an acute angle – it is there that the cracks are formed most often.
In winter, a particular danger is rodents – mice and harespenetrating the garden in search of food. They snap bark on the stamps and lower branches, to which they can reach, causing significant harm to the trees.
The main danger for fruit trees in the cold season is Morozoboinsarising due to sharp temperature fluctuations characteristic of winter and early spring. Especially vulnerable to damage to the apple tree, pears, plums and cherries, as well as young trees with fragile bark. At the same time, damage is localized mainly on the south side of the barrel – it is there that the sun's rays have the most intense effect.
Excessive soil moisture It can also provoke the appearance of cracks on the trunks of trees. This occurs when the soil is oversaturated with water due to severe precipitation, excessive watering or high groundwater. Moisture accumulates in an unevenly growing bark and turns into ice with the onset of winter, destroying wood from the inside.
Harm to trees can cause and Excessive use of nitrogen fertilizersthat stimulate the active growth of green mass .. Young shoots that are actively growing thanks to nitrogen do not have time to grow up before the onset of cold weather and often die in the first frosts.
“The appearance of damage and wounds on the bark of a tree is a serious situation that can lead to many negative consequences for the health of the garden,” they warned in the publication.
Context
