No regular fertilization needed; low-nutrient soils support healthy growth. Avoid nitrogen-rich fertilizers, which can encourage excessive foliage growth over blooms
Banana peel compost tea：Use fully composted banana peels steeped in water; dilute 1:20 for root drench to avoid nutrient burnPruning
- Deadhead spent flower heads to extend the blooming period through late summer
- Cut back all foliage to ground level in late autumn after plants go dormant
