Care Guide

Watering

Water moderately, allowing the topsoil to dry out completely between waterings.

Fertilization

Apply a balanced organic compost or mild fertilizer once at the start of the growing season.. Requires minimal feeding; over-fertilizing can lead to excessive, unmanageable vegetative growth.

Banana Peel Tea:Soak chopped banana peels in water for 24 hours. Strain and use the liquid to water the base of the plant. Avoid leaving solid peels on the soil to prevent pests.
Pruning
  • Prune in late winter or early spring to control size and shape;
  • Remove dead, damaged, or overly tangled stems to improve air circulation;
  • Always wear thick, puncture-resistant gloves when pruning due to the sharp prickles.
