The trunk, branches and twigs of a cherry tree are protected from the outside by the bark. Often the bark is infected by fungi or bacteria. Keeping the bark of a cherry tree healthy is important to the healthy tree.
The healthy bark
In the cold season, a cherry tree can be recognized from afar by its bark. The healthy cherry tree bark is smooth and shiny, green on young twigs, gray to reddish brown on older twigs and contains rust-colored horizontal stripes. The term "bark" is generally equated with the term "bark". However, the bark is only the outer blackish part of the bark, which gradually peels off the trunk like a ring. It is therefore referred to as "Ringelbarke".
The diseased bark
Diseases of cherry trees are often fungal infections that affect the bark. In the case of fruit tree canker, the affected areas become dry, the bark cracks and tissue growths form in the cracks. Valsa disease manifests itself in the fact that the surface of the bark warts, discolours, sinks and gum flow oozes from it. The affected areas should be removed and destroyed.
The injured bark
In order to keep the bark healthy, damage should be avoided as far as possible. If the cuts cannot be avoided, e.g. B. when grafting or grafting as well as annual pruning, good wound care is important. The cuts should always be made with a sharp knife.
tips and tricks
The injuries of the bark are closed by the so-called callus tissue, which accelerates the healing of the wound. Depending on the size of the wound, the resulting scars remain visible for a few years.
