Reduce watering; allow longer drying periods; begin light feeding with diluted cactus fertilizer monthly
Pre-flowering maturity
3-6 monthsPlant reaches 1-2 inches in diameter with well-developed spines and compact form; clustering increases
Provide cooler winter rest period (50-55°F) for 6-8 weeks to trigger flowering; water very sparingly
Flowering

Harvest Tips
Dwarf Chin Cactus is primarily grown for ornamental flowers rather than harvest. Enjoy flowers in spring and early summer without cutting them. Propagate by carefully removing offsets (baby rosettes) that form at the base once they are 0.5-1 inch in diameter; allow offset wounds to callus for 3-5 days before planting in dry soil.
