How to Grow and Care for Curio sulcicalyx
Light: Keep Curio plants in partial shade if outdoors, which is their preference in summer, and bright sunlight if indoors. They will grow in full shade but will become lank and leggy.

Fertilizing: The members of this genus can take a bit more fertilizer than other succulents if you want them to grow fast.
Repotting: You do not need to repot Curio plants often. You can do it when you see that the container becomes too small or shallow.
