Crassula socialis, like many other members of the genus, grows easily outside its natural habitat. Grow it in semi-shade in well-drained, preferably shallow soil. Keep it in pots until it forms clusters. The growth medium may be peat/sand mix or an inorganic sterile medium which will require fertilizing and watering. Add grit to the compost to improve drainage. Water twice a week, fertilize once a year. They should be lightly watered, even during their summer resting period, to prevent the soil becoming too dry which causes the roots to die back. For best performance they should be repotted once a year. Remove old inflorescences and dead leaves.

This crassula is ideal for rock gardens, stone walls, retaining walls and small empty spaces. Plant them in areas where they do not have to compete with other plants for space or where there is risk of them being smothered by larger more vigorous plants. They don't require large amounts of water and are highly suitable for water-wise gardens.

C. socialis, like many other members of the genus, is very easy to propagate. The best method is vegetative propagation. Take cuttings by removing a single rosette, and plant this directly into the soil. Handle the cuttings with care as they are brittle and easily break apart. A medium of gritty sand and sifted peat is the best to use, but the plants thrive in most media with adequate drainage. Water them twice a week. Grow them in partial shade as they suffer if they are overexposed to sunlight. They may be propagated throughout the year but the ideal time is during their growing season which is in winter from June to October.

Main pests are mealy bug, snout weevil and aphid. Main diseases are caused by fungi, such as rust and black or brown rot. Deal with these by applying systemic pesticides and fungicides.
