Care Guide

Watering

Water deeply and regularly to maintain even moisture during the active growing and blooming phase.

Fertilization

Apply a balanced, slow-release organic fertilizer as new growth appears.. Avoid excessive nitrogen, which promotes leafy growth at the expense of flowers.

Banana Peel Tea:Steep chopped banana peels in water for 24-48 hours. Strain and use the liquid to water the base of the plant to encourage robust blooming. Discard the peels in a compost bin to avoid attracting pests.
Pruning
  • Prune immediately after flowering in mid-summer to control size and shape.
  • Thin out up to one-third of the oldest woody stems down to the base to encourage vigorous new shoots.
  • Remove any dead, diseased, or crossing branches to improve air circulation.
  • Avoid hard pruning in late autumn or winter, as this removes the wood that will produce next year's flowers.
