Whether between stone joints, in the foreground of the perennial bed, at the edge of the path, in a pot on the balcony or on a dry stone wall - the stone herb will quickly find a place to grow. But it only stays healthy and blooming with a little care.

When and how is the pruning done?
After the first wave of flowers is over, the alyssum should be cut back. This pruning encourages a second bloom in late summer. At the same time, the stoneweed is prevented from investing too much energy in the formation of seeds. In autumn you can cut back the plant heavily if it is outdated or has become lazy.
When should you water the stonecrop?
The Alyssum survives dry periods without any problems - provided it was planted a few weeks ago. And yet it is grateful when it is poured in persistent heat and drought. Even in tub culture, it must be regularly supplied with water. Make sure it doesn't dry out!
Once the top layer of soil has dried, you can water. It doesn't matter whether you use calcareous tap water or rainwater. The Alyssum tolerates both. Water evenly and avoid waterlogging!
Does the Alyssum need fertilizer regularly to be able to grow and bloom well?
When fertilizing you should consider the following:
- basically not necessary
- also tolerates poor soils
- Fertilization is helpful for rich flowering
- it is best to fertilize after pruning in summer
- Use liquid fertilizer, compost or horn shavings (32.93€).
- do not fertilize too much, otherwise no flowers will form
What diseases and pests can harm it?
Alyssum is not usually susceptible to disease. Should mildew nevertheless occur, for example due to damp weather, the affected parts are cut off. Slugs and snails can cause problems for the alyssum.
tips
Often the stone herb is not hardy. You can therefore pull it out and compost it in late autumn. Before that, it is advisable to shake the plants so that seeds fall out, which will self-sow in spring.
