One of the few diseases that occurs on privet is leaf spot fungus. With an otherwise healthy hedge, you don't have to worry as much. If the infestation occurs very frequently, location and care errors can be responsible. How do you fight leaf spot fungus on privet?

Spots on the leaves can be the result of leaf spot disease

Signs of an infestation with leaf spot fungus

If the leaves of the privet turn yellow in autumn, this usually has a natural cause. There are also yellow species like the gold privet, which always have yellow leaves.

If yellow leaves appear on a green variety in summer and spots also appear on the upper side, you must assume an infestation with leaf spot fungus.

Causes of leaf spot fungus on privet

Various causes can be responsible. Usually, however, the spores of the fungus are already in the garden and are transferred to the privet.

Unfavorable site conditions and a climate that is too humid or too dry can favor the spread of the leaf spot fungus.

Control leaf spot fungus on privet

There is not much you can do if the leaf spot fungus has attacked the privet. There are only a few sprays that are approved for private gardens at all, and these are usually not very effective.

If the infestation is not too severe, you do not need to fight the fungal infestation. The privet can handle it on its own. If you are very bothered by the sight, generously cut off all affected shoots and dispose of them in the household waste - not in the compost!

Pick up fallen leaves and do not leave them in the garden as the spores are in the leaves and can trigger a new infestation.

This is how you prevent the leaf spot fungus on the privet

  • Choose resistant varieties
  • do not keep too wet or too dry
  • occasionally but not too much fertilizing
  • Maintain plant spacing
  • Keep tools clean

The cleanliness of the garden tools is very important. Thoroughly clean all cutting tools before use to avoid transferring fungal spores from one plant to the next.

tips

Another fungal disease that can affect privet is powdery mildew. It is almost always powdery mildew, which occurs in very hot and dry summers. Downy mildew, on the other hand, prefers a humid climate.
