Care Guide
Watering
Keep soil consistently moist during active growth periods; avoid waterlogging the root zone
Fertilization
Apply slow-release granular fertilizer in early spring to support new growth and flowering. Avoid over-fertilization, as excessive nitrogen can reduce bloom production
Banana peel compost tea：Compost banana peels for 4–6 weeks to break down nutrients; dilute the tea 1:20 with water for root drenching to avoid nutrient burnPruning
- Remove dead, damaged, or crossing branches in late winter to early spring before new growth emerges
- Thin overcrowded inner branches to improve air circulation and reduce disease risk
