Sulcorebutia

This mini mountain cacti need a cool winter period at 5-9°C from November to March in any case. During this time they need dry soil. That is very important for the flowers as well as for their health. Without this dry cool winter period they normally wont get any buds. Use strong mineral cacti soil and cacti fertilizer as it is said at the direction. It is recommended to use a mixture of standard cacti soil and 50% pure mineral substatum, lava or pumice stone.
