Cacti, stone crops, and all succulent plants
Cactacee potting soil is fertile and drains well, making it ideal for succulent plants that do not tolerate waterlogging. In fact, the composition allows it to temporarily retain large quantities of water, enabling the plant to build up a supply, while also draining well to prevent waterlogging, which would lead to rotting of the roots and then the epigeal part of the plant. The addition of pumice sand (0–3 mm) also guarantees excellent macroporosity. Cacti generally require high temperatures, even in winter, and they grow well in full sun. If the outside temperature does not fall below 5–6°C degrees, they can be safely grown outdoors.
