Care Guide

Watering

Water deeply when the top 2 inches of soil become dry, especially during the first growing season.

Fertilization

Apply a balanced, slow-release fertilizer before new growth begins.. Avoid excessive nitrogen, which promotes leafy growth at the expense of flowers and berries.

Banana Peel Tea:Steep chopped banana peels in water for 24 hours. Dilute the liquid 1:1 with water and apply to the base of the plant to support prolific flowering and fruiting. Discard peels in compost to avoid foul odors.
Pruning
  • Timing: Prune in late winter or early spring before new growth starts;
  • Safety: Always wear thick, puncture-resistant gloves to protect against sharp thorns;
  • Technique: Remove dead, diseased, or crossing branches to improve air circulation;
  • Fruiting: Shape carefully, keeping in mind that flowers and fruits form on the previous year's wood (old wood).
