Watering frequency: Sparingly; water deeply during active growth (spring to early autumn), then allow soil to dry completely. No water in winter dormancy.
Light exposure: Full sun to bright, indirect light. Protect from intense midday sun in very hot climates.
Temperature requirements: Prefers temperatures between 10°C to 35°C (50°F to 95°F). Protect from frost.
Fertilization: Minimal; apply diluted cactus fertilizer once in spring.
Pruning: Not required, but remove spent flowers to maintain appearance.
Common pests: Watch for mealybugs and root rot if overwatered. Use insecticidal soap or neem oil if needed.
