Fertilization

Apply balanced liquid fertilizer once monthly. Avoid over-fertilizing to prevent excessive foliage growth at the expense of blooms

Banana peel compost tea：Soak fully composted banana peels in water for 24 hours; dilute 1:20 with water for root drench to avoid nutrient burn

Pruning

Deadhead spent blooms regularly to encourage continuous flowering through the growing season
Cut back stems to ground level in late autumn after foliage dies back to prepare for winter dormancy
Thin overcrowded clumps every 2–3 years in early spring to improve airflow and reduce disease risk
