The soil should be rich in nutrients and permeable to prevent waterlogging. Favorable is a loamy-sandy soil with a calcareous impact. The kings lilac copes well with slightly acidic conditions.

Important care measures

To water:

The robust shrub needs little care. The best planting time is in autumn, because then the king lilac will grow well until the next spring. After planting, he must be supplied with plenty of water in the first few weeks. Then only if it is very warm and dry for days.


All lilacs are strong eaters and grateful for organic fertilizers or compost in spring. After flowering, you can fertilize weak again. At this point you should also remove the faded inflorescences directly at the base.


A shape cut is not necessary. You only have to cut out dead branches generously. In older, woody lilac shrubs, you can rejuvenate in autumn with a radical pruning of the main branches. However, next year the king's lilac will not bloom. Only in the following year, the shrub shows its flowers again.


The kings lilac is hardy. He therefore needs no special frost protection.
