Fertilization

Apply balanced slow-release fertilizer once at the start of growth. Avoid excessive nitrogen to prevent flopping of tall culms

Composted banana peel tea:Soak fully composted banana peels in water for 24 hours; dilute 1:20 with water for root drench to promote healthy growth without causing nutrient burn
Pruning
  • Cut back dead foliage to 5–10 cm above soil level in late winter before new spring growth emerges
  • Remove spent flower plumes after blooming to maintain a tidy appearance and encourage potential rebloom
  • Thin overcrowded clumps every 2–3 years in early spring to improve airflow and prevent disease
