Care Guide

Watering

Water regularly to support root establishment; reduce frequency once mature

Fertilization

Light, balanced slow-release feed once in early spring. Over-fertilization can reduce bloom production and weaken clump structure

Banana peel compost tea:Compost banana peels for 2–3 weeks, dilute 1:20 with water for root drench to support flowering and overall plant health
Pruning
  • Cut back dead foliage to 10–15 cm in late winter before new spring growth emerges
  • Remove faded flower plumes in early winter to maintain a tidy clump appearance
  • Divide overcrowded clumps every 3–4 years in early spring to promote vigorous growth
