fire blight
This disease affects a variety of deciduous trees. It is classified as dangerous and is therefore notifiable.
It can be recognized by the fact that the flowers and young shoots turn brown or black. The leaf veins are strikingly dark. A sure distinguishing feature is that the infested tree parts do not fall off in winter but remain on the tree.
Chemical remedies against fire blight do not exist yet. It remains only to cut off all affected parts of the mountain ash and dispose of safely.
Baumpilze
The most common fungi that attack the mountain ash are tree sponge and sulfur fungus. They form on the stem of rowan. There mushrooms sometimes grow to considerable specimens.
A berry tree infected with tree fungi is usually lost forever. Once the fungus is visible, you must assume that the spores have already spread in the trunk. Nevertheless, you should definitely eliminate the fungus. Otherwise, there is a risk that the spores pass on to other, healthy trees and also infect them.
Preventively observe your mountain ash carefully and intervene immediately even with the slightest fungal attack.
Gray mold
When fresh shoots of mountain ash turn red, dry out and fall off, gray-blight can be responsible.
Cut off all affected shoots directly on the trunk. This prevents further spread of the disease.
Gray rot occurs only in an unfavorable location of mountain ash, when the soil is too wet. Make sure that the rowanberry grows on a well drained soil that can not accumulate waterlogging.
Dispose of infected tree parts safely
Incinerate infected shoots and leaves as well as mushrooms or put them in the household waste. Under no circumstances may they be disposed of on the compost.
Tips & Tricks
In the treatment of diseases of the rowanberry, you should avoid using chemical agents as much as possible. They damage the birds, for which the fruits of mountain ash are an important food source.
