Establishment
2-4 weeksRecently planted or propagated cactus is developing roots and acclimating to its location
Water sparingly for first 2-3 weeks to prevent rot; place in bright indirect light initially; do not fertilize
Vegetative Growth
Spring through early summerCactus develops new stems and clusters, growing outward and upward with visible spine development
Provide full sun once established; water during spring and summer when soil is dry; light fertilizing with low-nitrogen cactus fertilizer monthly
Flowering
4-6 weeks, typically March-MayMagenta, pink, or purple flowers emerge from areoles along stems; blooms are typically 2-3 inches wide and extremely showy
Maintain consistent watering but allow brief dry periods; do not move or disturb plant; flowers last several days
Dormancy Preparation
August through OctoberPlant slows growth as days shorten; flowers finish and spines may develop deeper color
Gradually reduce watering in late summer and fall; withhold fertilizer; ensure plant remains in cool environment (50-60°F ideal)
Winter Rest
November through FebruaryPlant is essentially dormant with minimal visible growth; may appear slightly shriveled (normal)
Minimal to no watering; keep in cool, dry location; cold period (40-50°F) for 6-8 weeks triggers better spring flowering
