Fertilization

No regular fertilization required; tolerates nutrient-poor soil. Avoid over-fertilization, which can reduce bloom density

Composted banana peel tea:Use fully composted banana peels steeped in water for 24 hours; dilute 1:20 for root drench to support bloom health
Pruning
  • Deadhead spent blooms to prevent excessive self-seeding if grown as an ornamental
  • Thin overcrowded stems to improve airflow and reduce disease risk
