Cultivation and Propagation: Cyrtanthus spiralisSN|22319]]SN|22319]] is one of the most difficult members to cultivate successfully over an extended period. It is usually evergreen in cultivation but needs to be kept almost dry during its dormancy as the bulbs is disposed to dwindle and rot. Its summer rest must be absolute. Water sparingly when growing and a little care, it is a definite water-wise species. Coarse river sand or gravel must be incorporated into the growing medium for excellent drainage.
