Identification features for various pests
Swelling the leaf buds, but do not drive, are responsible for gall bladder. Spider mites and scale insects leave stains and small holes on the top of the leaves. On the underside of leaves you will discover the pests.
The larvae and maggots of alder leaf beetle, frost spinner, cockchafer and oak winder cause great damage to the leaves. Often you will find the larvae and maggots or the beetles and butterflies themselves on the leaves.
If the hornbeam becomes brown and withered, although it was cast frequently enough, mice may be responsible. They eat the roots. In the case of severe damage, you can simply pull the hornbeam out of the ground.
Fight pests
For small pests, cut off all affected plant parts generously. The hornbeam does not matter. She also recovers from a strong cut to the old wood again.
Larger pests such as maggots and beetles can be collected. Stop ant trails that lead to the hornbeam to fight lice.
Do you have mice in the garden, you should definitely do something to keep them away from the roots of hornbeam.
Prevent pest infestation
A healthy hornbeam makes a slight pest infestation not so much. Make sure the hornbeam looks ideal.
Dryness or too much wetness favor pest infestation. Pour younger hornbeams more often. This is no longer necessary with older trees.
Cut the hornbeam at the beginning several times a year. The cutting drastically reduces the number of pests, so the infestation is not so strong.
Tips
If the spots on the leaf tops are multicolored, look under the leaves. If these are covered by a fungal turf, the pest is a fungus that needs to be treated. The fungal disease powdery mildew occurs more frequently on the hornbeam than animal pests.
