Watering

Keep soil consistently moist but not waterlogged during active growth

Fertilization

Apply balanced diluted liquid fertilizer once monthly. Use a low-nitrogen fertilizer to prioritize flower production over foliage growth

Banana peel tea：Chop 2–3 banana peels and soak in 1 liter of water for 24 hours; strain and use the liquid to water base of plants directly

Pruning

Deadhead spent blooms regularly to encourage extended flowering through early autumn
Cut back all foliage to ground level in late autumn after first frost to prepare for winter dormancy
Thin overcrowded clumps every 2–3 years in early spring to improve airflow and reduce disease risk
