How to care for your Red Crown Cactus
Everything you need to keep your Red Crown Cactus healthy: watering, light, humidity, feeding, repotting and pruning.
The Red Crown Cactus is a delightful, small globular cactus that readily produces offsets, forming attractive clumps. It is highly valued for its abundant, showy red or orange flowers that often form a ring around the base of the plant in spring. This easy-to-care-for cactus thrives in bright, indirect light and well-draining soil. Water thoroughly during the growing season, but keep it almost completely dry during its winter dormancy to encourage prolific spring blooms.
