Sow cactus seed from January to April. Sow cacti on the surface of a free draining, gritty compost and cover with a very fine sprinkling of silver sand. Place in a propagator or seal the seed tray inside a polythene bag, maintaining a temperature of 20-25C (68-77F) until after germination, which can be erratic and usually takes between 1 - 3 months. Do not exclude light when growing cacti as this helps germination. Keep the surface of the compost moist but not waterlogged. When seedlings are large enough to handle, transplant them into trays or 5cm (2") pots of gritty potting mix and continue to grow in warm conditions. Once they are well grown, pot cactus plants on into 7.5cm (3") pots, and water carefully until established.
Cactus plants are slow growing so patience is required. Grow cacti in full light with some shelter from the hottest sun. In summer, water cacti regularly with soft water or rain water. Allow the compost to dry out slightly between watering. In winter, while the plant is dormant, gradually reduce watering and allow the compost to remain dry.
