Care Guide
Watering
Keep soil evenly moist during active growth; allow top 2 cm to dry between waterings
Fertilization
Diluted balanced liquid feed once every 2 weeks. Discontinue fertilization in late autumn as growth slows
Banana peel compost tea：Compost banana peels for 2–3 weeks to break down nutrients; steep in water for 24 hours, dilute 1:20 for root drench to avoid nutrient burnPruning
- Remove spent flowers promptly to prevent aggressive self-seeding and reduce spread in managed gardens
- Thin overcrowded stems to improve airflow and lower risk of fungal infections
- Cut back dead foliage to ground level in late autumn after the plant dies back
