Care Guide

Watering

Keep soil consistently moist but not waterlogged; mist leaves 2–3 times weekly to boost humidity

Fertilization

Diluted balanced liquid fertilizer every 2 weeks. Avoid over-fertilizing, as excess nitrogen can cause faded variegation and leggy growth

Banana peel compost tea:Compost banana peels for 2–3 weeks, steep in water for 24 hours, dilute 1:20 with water for root drench; avoid applying to foliage to prevent staining
Pruning
  • Pinch back growing tips every 2–3 weeks to encourage bushy, compact growth
  • Remove flower spikes promptly once they appear to redirect energy to foliage development
  • Trim leggy stems in early spring to refresh plant shape and promote new growth
  • Remove yellowing or damaged leaves to maintain plant health and appearance
