Astrophytum, Mixed Species

Germination

Sow indoors. Surface sow onto moist, well-drained seed compost. Sand and loam with sphagum moss or coir makes a good mix. Just cover seed with a little grit or sand. Propagate or move somewhere warm and dark, ideal temp. 25°C. Germination takes 5-180 days, even under good conditions germination can be erratic. As the seeds start to germinate increase the light and decrease the humidity. Transplant seedlings when large enough to handle to individual pots and grow on.

Growing

Grow under glass in a cactus compost. Prefers bright, filtered light. Lightly water during the growing season but keep dry when dormant. In warmer climates may be grown outside in full sun and brought inside as the weather cools.

Cultivation

No pruning required.
