If you live in a northern area with cold winters, choose a delosperma variety that can withstand frigid temperatures. Delosperma cooperi, Delosperma congestum and Delosperma basuticum are three varieties that perform well in frigid winters. Delosperma Ashtonii and Delosperma Sutherlandii are better varieties for warmer climates. For indoor planting, choosing a particular variety is less crucial.
Delosperma does not require a lot of nutrients, and, in the presence of excess nutrients in the soil, the plant will grow too quickly, with spindly stems and few blooms. Make sure that you plant delosperma in soil that is primarily sand or grit with lots of drainage. Prime planting locations are in the upper beds of rock gardens and in raised, sandy flower beds.
Since delosperma hails from an arid region, it does not require much water. Between waterings, allow the plant leaves to dry out a little, then water sparingly.
When choosing a spot to plant delosperma, opt for the sunniest area of your garden. Delosperma thrives in full sun. If you grow delosperma indoors, make sure you place pots near windows that get optimal light and rotate the pots regularly to ensure that all parts of the plants get the sun they crave.
