Care Guide

Watering

Water occasionally during prolonged dry periods to support flowering

Fertilization

No regular fertilization needed. Excess fertilizer can reduce flowering and encourage leggy growth

Composted banana peel tea:Use fully composted banana peels; dilute 1:20 for root drench to support bloom production without overfertilizing
Pruning
  • Deadhead spent flower spires to prevent unwanted self-seeding if desired
  • Cut back entire stems to ground level after flowering in late autumn
  • Remove any diseased or yellowing foliage in early spring to improve airflow
