How to Grow and Care

Titanopsis is easy to grow and clumps readily, forming a beautiful succulent mat. The clumps can be divided for further propagation of the plant. Needs moderate water when growing in late fall and early spring. Keep somewhat dry the rest of the time.

The maintenance of Titanopsis is not difficult. They need a sandy substrate with little organic material. They are winter grower, and should be kept relatively dry in summer. They should also be kept dry when the temperature is below 45° F (7° C). The best place to grow Titanopsis is a sunny spot where it gets bright sunlight in summer and direct exposure to the sun in winter.

Division of larger clumps is possible in some cases, but as most species have tuberous rootstocks and offset slowly, seed production is the most common method of propagation. Sow it in spring and it should start flowering after two years… – See more at: How to Grow and Care for Titanopsis
