Illness or care mistake?
Harlequin willows rarely suffer from any disease. If your plant still looks unhealthy, you should first check the plant for care errors. These cause symptoms similar to, for example, withered leaves.
- Is your harlequin pasture too sunny?
- Are you watering the plant too little?
- Are there enough nutrients?
- Did you overfertilize the tree?
- Has waterlogging formed in the bucket?

The Willow Borer
After you have checked the harlequin willow for the consequences of care errors and have adapted them to the species-appropriate attitude, the symptoms should improve soon. Otherwise, you should actually assume an illness. In this case, the harlequin willow is particularly susceptible to a parasite, the Willow Borer.
Symptoms
- Older pastures in particular are affected
- Feed marks in the wood
- dark red or white larvae ten centimeters long on the leaves
- Brown leaves
- Leaf shedding
- In the final stage, the harlequin willow dies
measures
Only a radical pruning can help against any disease. However, you have to be careful not to cut into the refining point of the trunk. Otherwise, you should carefully remove all infected shoots. Don't be afraid to cut back the willow heavily. The regular exposure of the crown also promotes the incidence of light. If the branches branch too much here, the harlequin willow will also show crooked growth. The sapling will soon sprout again.
Never dispose of the clippings on the compost. The parasite could multiply here and migrate again to the harlequin pasture in the following year.
Prevent
Since it is often too late by the time the first symptoms show up, prevention is the best treatment you can take. Always check your harlequin pasture for abnormalities in order to detect a possible disease early enough.
Note: You cannot avoid using a fungicide for some diseases. In this case, you should only resort to chemicals in an extreme emergency. Inquire beforehand in specialist shops about organic and environmentally friendly alternatives.
