Trichodiadema stayneri can be easily grown from stem cuttings and seeds, however, cuttings are most preferred as rooting is almost guaranteed at optimum conditions. Source cuttings from healthy plants in active growth. Take 5–7 cm long cuttings, remove the lower leaves and plant the stems in a well-drained sandy mixture, preferably 2 parts river sand and 1 part garden loam or 2 parts perlite and 1 part peat. Keep the cuttings moist and in a warm area away from direct sunlight until rooting is observed. Rooting takes place in two weeks. Transplant the rooted plants into individual nursery pots or bags in a sandy soil mix. Water twice a week, giving moderate amounts of water.

Trichodiadema stayneri has not yet been propagated from seed in Kwelera National Botanical Garden, however, the seeds of Trichodiadema species can be sown in autumn between April and May, in a soil mix of 2 parts fine river sand and 1 part potting soil. Spread the seeds on top of the soil in shallow seed trays filled with the sandy mix and cover the seeds with a thin layer of the sandy mix. Place the trays in a warm area away from direct sunlight. Water with a fine nozzle spray every second say. Germination takes place within 2 weeks.

Stayner’s diadem vygie is well-suited for gardens that experience hot summers and sporadic rainfall throughout the year. It can be planted as a ground cover to control erosion in a waterwise succulent garden, in a sunny position and could also be suitable as a container and bonsai subject.
