The Aeonium Zwartkop can be grown directly in the garden in suitable climates and also in pots, with a mix of potting soil with special soil for succulents and cactus.

If they are cultivated in pots, it is necessary to place a layer of volcanic gravel in the bottom of them to facilitate the drainage and not to place plates, so that the water of irrigation flows freely.
