Care Guide

Watering

Water deeply once a week during active growth and blooming periods.

Fertilization

Apply a balanced, slow-release fertilizer in early spring to support new growth.. Avoid over-fertilizing, which can lead to excessive foliage growth at the expense of flowers.

Banana Peel Tea:Steep chopped banana peels in water for 24-48 hours. Dilute 1:1 with water and pour around the base of the vine to promote blooming. Discard the used peels in an outdoor compost bin to avoid attracting fruit flies.
Pruning
  • Winter Pruning: Prune hard in late winter or early spring before new growth begins to control its aggressive spread;
  • Thinning: Remove dead, diseased, or tangled interior vines to improve air circulation;
  • Shaping: Trim back after the main summer flush of flowers to maintain shape and keep it within its trellis or support.
