TIPS FOR GROWING
These are our tips for growing Gibbaeum:
- It is recommended an exposure in full sun, but it is also suggested to accustom the plant to the sun gradually, if you move the succulent from a shady place (as for example if it is a young plant, which developed from cuttings in a sheltered environment).
- Because it comes from the hottest areas of the planet, the Gibbaeum does not stand low winter temperatures. It must be kept above 10 ° C and put indoors during the colder months.
- Water regularly in summer once every 5-6 days, during the growing season. Some varieties have an inverted vegetative period and in this case they must be watered especially in winter. In general, the irrigation must be suspended when the leaves begin to shrivel and started again when the first leaves are visible.
- Use a well-drained soil, like all succulents, and with low acidity.
- Being small-sized plants, there is a little need of fertilization and of repotting.
The Gibbaeum reproduce by seed and by cuttings.
As cuttings, it is usually used the leaf, cut as close as possible to the base and pleaseuse a sterile blade. As with other species with leaves, it can be necessary a few days to dry the wound and to replant the cuttings in a sandy substrate.
