Lack of water
A lack of water in lilacs is particularly noticeable in hot dry periods: the shrub then initially lets its leaves hang down and gradually dries out. The leaves are then shed to reduce evaporation. The ornamental wood has very large leaves that condense a lot of water.

But before you reach for the watering can, it is better to double-check whether the lack of water is actually the correct reason for the leaf shedding.

To treat the lilac, you have to cut the infected parts of the plant back into the healthy wood and collect any leaves that have fallen on the ground. These must either be disposed of with household waste or burned, but must never end up on the compost.
Pest infestation
The larvae of the Lilac terminator moth feed on the leaves of the lilac. You can first recognize an infestation by the fact that the leaves get brown spots, curl up, dry up and finally fall off. In the current year, treatment other than collecting infested leaves is not necessary. In the following year you can spray neem to sprout leaves.
Tips
