Anacampseros telephiastrum is one of the more common species in cultivation and quite resistant to cultivation. The only things that can kill this plant are cold and overwatering. Nevertheless, it is appropriate to provide adequate growing conditions in order to obtain compact plant with many flowers. 
Growth rate: Slow growing to start but does well under cultivation. They need to be moderately large (about 20 cm in diameter) before they flower.
Soils: Use a an open and free draining mineral compost with little organic matter (peat, humus) that allows therefore roots to breath (as it is rot prone). Outdoors a well-draining rocky or sandy soil is ideal. 
Repotting: Repot Anacampseros telephiastrum once a year in order to evaluate the health of the plant and provide a larger growing space being careful not to damage the sensitive roots.
Watering: It likes a winter's rest and should be kept completely dry during the winter months. From early spring onwards the plant will begin to grow and watering should be increased gradually until late spring when the plant should be in full growth. Water regularly during the aestival growth cycle so long as the plant pot is allowed to drain and not sit in a tray of water (this plant need plenty of water) But needs to be avoided wetting the bodies of these plants while they are in sunlight. A wet plant in the sun light can cause sun burning which can lead to scars or even fungal infections and death. From late summer watering should be reduced to force the plant to go in to a state of semi dormancy, by autumn you should be back in to the winter watering regime. Keep dry with ample airflow in winter (but for outdoors cultivation it is somewhat resistant to wet conditions, too if grown in very draining substrata). In the rest period no high atmospheric humidity!! Care must be taken with watering as they tends to become swollen and untidy in growth habit if given too much water and shade. 
Fertilization: Feed with a high potassium fertilizer in summer during the growing season diluted to one-fourth potency and mix into the watering can for application.
