Care Guide

Watering

Water deeply when the top inch of soil dries out to support active vine growth.

Fertilization

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

Banana Peel Tea:Soak chopped banana peels in water for 24-48 hours. Strain and use the liquid to water the base of the vine to support robust root and stem growth. Discard solids in compost to avoid attracting pests.
Pruning
  • Prune in late winter or early spring before new growth begins;
  • Remove dead, damaged, or crossing vines to maintain good air circulation;
  • Cut back aggressively if the vine outgrows its designated trellis or support space.
