Care Guide

Watering

Keep soil consistently moist but not waterlogged during active growth

Fertilization

Apply a balanced organic fertilizer once at the start of growing season. Avoid high-nitrogen fertilizers to prevent excessive foliage growth at the expense of flower production

Banana peel compost tea:Use fully composted banana peels steeped in water for 3 days; dilute the tea 1:20 with water before applying as a root drench; discard solid peels to avoid pest infestations
Pruning
  • Remove dead, damaged, or crossing branches in late winter to improve air circulation
  • Thin crowded inner branches to allow light penetration to lower foliage
  • Shape the canopy lightly immediately after flowering to maintain a rounded form
