Care Guide

Watering

Keep soil consistently moist during active growth periods

Fertilization

Diluted balanced organic feed once every 2 weeks. Use low-nitrogen feed to promote flower production rather than excessive leaf growth

Banana peel compost tea:Compost banana peels for 2–3 weeks to break down, steep in water for 24 hours, dilute 1:20 with water for root drench; avoid using raw peels to prevent pest infestations
Pruning
  • Deadhead spent flower heads to prevent unwanted self-seeding in managed gardens
  • Remove yellowing basal leaves to improve airflow and reduce disease risk
  • Cut back stems to ground level after flowering to encourage healthy regrowth the following season
