Care Guide

Watering

Keep soil consistently moist but not saturated; increase frequency during prolonged hot, dry spells

Fertilization

Apply balanced liquid feed every 2 weeks during active growth. Use low-nitrogen fertilizer to prioritize flower production over excessive leaf growth

Banana peel compost tea:Soak fully composted banana peels in water for 24 hours; dilute 1:20 for root drench; discard solid peels to avoid pest infestations and odor
Pruning
  • Deadhead spent flower clusters promptly to encourage extended blooming period.
  • Cut back dying upright stems to ground level after flowering to tidy the basal rosette.
  • Remove damaged or yellowing leaves to improve airflow and reduce disease risk.
