Both too much and too little water has bad effects on the lilac
Help, the lilac dries up! What to do?
Even the sturdy and easy-care lilac can be plagued by health problems from time to time. For example, if the shrub has dried up, you should not immediately reach for the watering can. Instead, take the time to explore the specific cause. Only then can you specifically help your ailing lilac.
What causes the lilac to dry up - The most common causes
At this point we have for you the most common causes that lead to the drying of the lilac and possible treatment methods. In many cases, damage or impairment of the roots and thus a lack of supply of above-ground plant parts with water and nutrients underlie. But also the pathways themselves can be affected, so that the roots no longer reach all shoots. As a result, these die off. For example, this is often the case after moving an older lilac, when a large part of the root system is cut and at the same time no pruning has been done - fewer roots supply less aboveground plant parts, which is why some others simply dry up.
water shortage
In particular, when it is hot and dry, the lilac can quickly be thirsty, especially in sandy soils. The first signs of a lack of water are the leaves, which initially hang limply and later dry up and fall off. By contrast, only thorough watering helps.
waterlogging
As paradoxical as it sounds at first: too much moisture can cause the lilac bush to dry up. Here, however, the lack of water is due to the fact that the constantly in the moisture roots rot due to fungi and bacteria and therefore can no longer provide the lilac. Sometimes you save the plant by a courageous pruning and moving into drier soil.
soil pests
Voles and grubs - those are the larvae of the May beetle - eat with preference the roots of the lilac. As a result, it can no longer be supplied and dies.
Diseases
Some pathogens can cause a wilting that causes first individual shoots and later the whole plant to die. These include, for example, Verticillium fungi or lilacs caused by the bacterium Pseudomonas syringae. In all cases, only a strong pruning helps to healthy wood.
Tips
Although the lilac needs a sunny as possible location, but can at very exposed places and at high heat quite "burn". This can be recognized by brown leaf spots, until the leaves and shoots wither. When planting, therefore, pay attention to a breezy, even windy location.
