If the bark of lilacs peels off over a large area, this is not necessarily a sign of a loss of vitality in the tree. Nevertheless, a quick clarification of the trigger is recommended.
Why does the bark of the lilac come off?
If your lilac is anolder tree,is itnormal,that thebark has longitudinal cracksforms and separates in vertical stripes. The trigger can also be an infection with the fungus Verticillium albo atrum.
Can growth cause the bark of the lilac to come off?
With increasingage and thickness growthof the lilac trunk,longitudinal cracks appear on the trunk,from which vertical strips of bark detach.
So that the tree can continue to develop well, an adequate supply of nutrients makes sense:
- In the spring, spread compost under the lilacs and work it lightly into the soil.
- Since dryness also affects the condition of the bark, water the tree if necessary in the hot summer months.
Can bark damage occur due to verticillium wilt?
A characteristic of theVerticillium wiltis the strikinglywrinkled bark,which tears open intolong strips. Shoot tips, twigs and crown parts of the lilac die.
Take the following actions:
- Cut diseased branches back to he althy wood.
- In order not to spread the pathogen, disinfect the tools regularly.
- Since the spores can survive in the soil and on plant residues for several years, you should dispose of the clippings with household waste.
- Direct control by spraying is not possible.
