Step Two: Pour growing medium into peat pot at bottom of 10oz cup, and set plastic baggie aside.

good locations,

These seeds need very wet conditions with day time temperatures to be in the 80s and night time temperatures to fall into the 60s. The seedlings are very small and remain small for a few years, but they begin to grow faster after the first few years. The seedlings are small and fragile enough to need water frequently, and they thrive in wet warm conditions. The seedlings will have less risk of fungal infections if they are allowed to dry out between being in fully wet soil.

Gymnocalycium saglionis is sometime called, "Giant Chin Cactus" which is its common name.

These plants grow well under artificial plant lighting, and long exposures to the full force of sunlight should be avoided. If the seedlings are kept in sunlight they will do well on plenty of filtered light, because too much intense sun can damage the skin. This species will survive brief exposures to freezing conditions, but will need the temperatures to remain above 25 °F. If this variety is to be set outdoors during the growing season it needs to be in a location with filtered sun with only a few hours of direct sun, and will tolerate lots of rain. Keeping saglionis outdoors as seedling may require at least 30% shade cloth for protection from rain and sun.


Gymnocalycium saglionis remains a single stem plant and is perhaps the largest growing cactus in the generic. Very old plants can grow about a foot across and a few feet tall.
