Care Guide

Watering

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

Fertilization

Apply balanced liquid fertilizer every 2 weeks to support bract growth. Discontinue fertilization in autumn and winter during dormancy

Banana peel compost tea:Compost banana peels for 2–3 weeks, steep in water for 24 hours, dilute 1:20 with water before applying as a root drench to avoid nutrient burn
Pruning
  • Prune faded bracts and overgrown branches immediately after flowering to encourage new growth and compact shape
  • Remove dead or diseased stems to improve airflow and reduce pest risk
  • Train climbing stems to trellises or supports in early spring to maintain desired form
  • Trim back leggy growth in late winter to promote bushier growth in the growing season
