These diseases affect them

Abnormalities on the branches of the forsythia

Diseases are particularly noticeable in the drives. Not all abnormalities in the branches have to be due to the disease. The most common degenerative changes are:

• Association changes
• Drive galls
• Fungal diseases
• Instinct death

Association changes

The branches of the Forsythia thicken and look like would lie several bands next to each other. This is a genetic disorder. Flowers develop normally on it.

You don't have to undertake anything. Only if you are very bothered by the thickened areas, cut them off.

Drive galls

Shoot galls are noticeable through spherical thickenings at the shoot tips. The tissue overgrowths occur mainly in weak plants and are caused by a bacterium.

Remove the affected shoots. Sometimes a strong one helps Cut backto strengthen the shrub.

Fungal diseases

If the leaves curl up, wilt and fall off prematurely, it is usually a fungal disease. It is favored when the forsythia does not get enough air.

Again, cut the affected ones Forsythia branches and thinning out the bush.

Instinct death

When it is very wet in winter and spring, entire shoots occasionally die and the flower buds dry out. Both bacteria and harmful fungi can be responsible for this.

Cut off affected shoots generously. If possible, make sure that the soil is permeable to water so that the forsythia is not so damp.

Bedbugs can be a problem

Often in spring you will notice that the young leaves are perforated, as if caterpillars had eaten them. The cause are leaf bugs that pierce the leaves that are still rolled up in order to suck out the juice. The holes are created by puncturing the leaf.

The bugs themselves are hard to find because they drop to the ground immediately if they are threatened. So far, there is no effective fight against pests.

Tips & Tricks

Forsythia are very easy to care for. The bushes only really resent drought and waterlogging. Make a good one Locationto prevent disease.
