Causes and Measures (Syringa)

What causes the lilac to dry up - The most common causes

At this point we have compiled for you the most common causes that lead to the drying out of the lilac and possible treatment methods. In many cases there is damage or impairment to the root and thus an insufficient supply of the above-ground parts of the plant with water and nutrients. But the ducts themselves can also be affected, so that the roots no longer reach all of the shoots. As a result, they die off. For example, this is often after the Realize An older lilac is the case when a large part of the root system has been cut and at the same time no pruning was made - fewer roots supply fewer above-ground parts of the plant, which is why some others then simply dry up.

Lack of water

Especially when it is hot and dry, the lilac can quickly become thirsty, especially in sandy soils. The first signs of a lack of water are the leaves, which initially hang down limply and later dry up and fall off. Only thorough watering helps against this.

Waterlogging

As paradoxical as it sounds at first, too much moisture can cause the lilac bush to dry out. Here, however, the lack of water arises because the roots, which are constantly in the moisture, rot due to fungi and bacteria and can therefore no longer supply the lilacs. Sometimes you can save the plant by pruning it bravely and moving it to drier soil.

Soil pests

Voles and grubs - these are the larvae of the cockchafer - they prefer to eat the roots of the lilac. As a result, it can no longer be taken care of and dies.

Diseases

Some Pathogens can cause wilting, which initially causes individual shoots to die off and later the entire plant. These include, for example, Verticillium fungi or the lilac disease caused by the bacterium Pseudomonas syringae. In all cases, only a strong cut back into the healthy wood will help.
