Full sun to partial shade; tolerates intense arid sunlight but benefits from light afternoon shade in extreme heat
Watering
Drought-tolerant once established; water deeply but infrequently to encourage deep root growth and avoid root rot
Temperature
Hardy to -15°C; withstands high summer heat in arid regions but requires good drainage to prevent winter root damage

Care Guide
Watering
Water deeply every 7–10 days during active growth to support flowering
Fertilization
Apply a balanced slow-release fertilizer once at the start of growing season. Avoid over-fertilization, as it can reduce flowering and increase succulent growth prone to damage
Composted banana peel tea：Fully compost banana peels to eliminate odor and pathogens; dilute 1:20 with water for root drench to avoid nutrient burnPruning
- Remove dead, damaged, or diseased branches in late winter before new growth emerges
- Thin overcrowded stems to improve airflow and promote more abundant flowering
- Trim back suckers to maintain desired shape and prevent unwanted spreading
