Cornelian cherries are very rarely attacked by diseases
The Cornelian cherry is largely resistant to disease
Cornelian cherries are among the most robust fruit trees that exist in our latitudes. Illnesses therefore hardly ever occur. Only in very humid summer can the leaves suffer from fungal diseases. Pests pose no problems for the yellow dogwood.
Yellow, withered and deciduous leaves
Occasionally it comes to the leaves of the Cornelian show abnormalities, such as:
These are in most cases to fungal diseases such as leaf blotch or mildew, which occur especially in very humid weather.
Treatment for diseases
Only weakened, younger trees are seriously damaged by fungi. The older the Cornelian Cherry grows, the more resistant it is to fungal diseases of all kinds. Mulch the soil under the Cornelian Cherry so that it receives more nutrients. This simultaneously regulates soil moisture.
Cut off any affected branches and dispose of them with household waste or incinerate them.
The fungus itself can be cured with fungicides from the garden trade. In the interest of bees, bumblebees and birds, however, you should better resort to natural control methods. For example, inject the Cornelian cherry with:
If the infestation occurs repeatedly
As a rule, fungal infestation occurs once in the cornelian cherry. If the fruit tree shows the symptoms more often, you should search for the causes of the disease.
Often a too wet ground is to blame. Here it can be helpful to loosen up the soil and create a drainage.
Sometimes it helps to clear up the cornelian cherry and make sure it is not too close to other trees. Due to a good air circulation the fungal infestation can be kept within limits.
Pests are unknown
Cornelian cherries are resistant to pests. One of the reasons is that the wood is so hard that hardly any pests are worried about it.
Tips
The Cornelian cherry is so robust that it can cope with almost any soil. It is even resistant to road salt, making it ideal for hedging roads and roads.
