Delosperma sutherlandii is propagated by stem cuttings or by sowing the seeds and is frequently grown as a houseplant indoors in cooler temperate regions. It can be planted in coastal gardens, gravel gardens, beside patios and in containers, in rock gardens, on banks and slopes. Its dark grey-green leaves, bright magenta flowers in summer and mat-forming habit, make it a good ornamental ground-cover plant.

Growing conditions can be well-drained loamy or sandy soil of acid, alkaline or neutral pH. When growing in pots, the growing medium must not retain too much moisture. Plant it in a hole that is the same depth as the existing root system. Pot grown plants can be planted at any time, but spring is the best time, rather than summer, to plant them out in the garden. They also fare well in a gravel garden. It requires as much sunlight as possible, so it should be positioned in full sun. No pruning is required.

Common problems related to growing Delosperma sutherlandii is overwatering or poor drainage since waterlogging can cause rotting. This plant is generally disease free but may be susceptible to mealybugs, aphids and other common pests.
