Use compost with few added nutrients with s part added of coarse sandy grit and broken brick. Pot every three years in March, and give the plants a very sunny place in the greenhouse. Do not water between October and March, but between March and September water well when the soil in the pot has dried out. The winter temperature should not be less than 40°F (4°C).

mammillopsis senilis Propagate from seed sown in pans of regular seed compost, where a temperature of 70°F (21°C) can be maintained. Cover the seed lightly, keep it moist and shaded until germination, then give light but not direct sun. Offsets can be removed and rooted in coarse sand.
