Cornus cherries are among the most robust fruit trees that exist in our latitudes. Diseases therefore hardly ever occur. Only in very humid summers can the leaves suffer from fungal diseases. Pests do not cause any problems for the yellow dogwood.

Cornus cherries are very rarely attacked by diseases

Yellow, dried up and falling leaves

Occasionally, the leaves of the cornelian cherry show abnormalities such as:

  • curl up
  • mottled or yellow discoloration
  • greyish or whitish coating
  • dry up
  • premature leaf drop

In most cases, these are fungal diseases such as leaf spot disease or powdery mildew, which mainly occur in very humid weather.

Treatment for diseases

Only weakened, younger trees are seriously damaged by fungi. The older the cornelian cherry becomes, the more resistant it is to all kinds of fungal diseases. Mulch the soil under the cornelian cherry so that it receives more nutrients. This also regulates soil moisture.

Cut off infested branches and dispose of them with household waste or burn them.

You can tackle the fungus itself with fungicides from garden supply stores. In the interests of bees, bumblebees and birds, however, it is better to use natural control methods. For example, sprinkle the cornel with:

  • Fresh, low-fat milk
  • horsetail brew
  • Sheep brew
  • fern broth

If the infestation occurs repeatedly

As a rule, the fungal attack on the Cornelian cherry occurs once. If the fruit tree shows the symptoms mentioned more often, you should research the causes of the disease.

Too wet soil is often to blame. Here it can be helpful to loosen the soil and create drainage.

Sometimes it also helps to thin out the cornel a lot and make sure that it is not too close to other trees. Good air circulation keeps fungal infestation within limits.

Pests are not known

Cornelian cherries are resistant to pests. One of the reasons for this is that the wood is so hard that hardly any pests can tamper with 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 very suitable for hedges on paths and streets.
