Care Guide

Watering

Keep soil consistently moist during blooming and active growth periods

Fertilization

Apply balanced slow-release fertilizer in early spring before new growth emerges. Use a fertilizer with balanced nitrogen, phosphorus, and potassium to support both foliage and blooms

Composted banana peel tea:Fully compost banana peels for 2–3 weeks, dilute the resulting tea 1:20 with water for root drenching; avoid raw peels to prevent pest infestations
Pruning
  • Prune dead, diseased, or crossing branches in late winter before new growth begins
  • Thin crowded inner branches to improve air circulation and light penetration
  • Lightly remove spent blooms after flowering to redirect energy to foliage growth; avoid heavy pruning that reduces next year's bloom potential
