B. cremnophila is easily grown in containers. It requires partial shade for best results. It can be grown in hanging baskets or rockeries in Thicket Gardens (Van Jaarsveld 2010). Water well but allow soil to dry out before watering again (spring to autumn). B. cremnophila can also be grown in miniature succulent gardens thriving in an environment together with other succulent plants. It is easily grown in a sandy, humus-rich soil. Use a general succulent mix such as 2 parts sand, 1 part garden loam and 1 part compost. Add ample bone meal, and plants can be fed with an organic fertilizer. Propagation is easy by cuttings or division. Cuttings are best rooted in sand; the best time is during spring or summer. Keep them partially shaded. Once rooted, they can be transferred to containers. Plants can also be grown from seed planted in a well drained succulent soil. Broadcast on the medium and cover with a thin layer of sand 2-3 mm thick. Keep moist. Germination is usually within 3 weeks.

Plants are relatively disease-free but succumb rapidly to fungal rot when kept too moist. The aloe ring fungus (Uromyces sp.) can be troublesome but is easily treated with a fungicide. When grown as a pot plant, it is best to replant every second or third year in fresh soil at the end of the resting season (early spring).
