Care Guide

Watering

Water deeply when the top inch of soil feels dry, typically 2-3 times a week during hot spells.

Fertilization

Apply a balanced organic fertilizer to encourage strong root and foliage growth.. 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 boost bloom size and color. Discard solids in compost to avoid attracting pests.
Pruning
  • Deadheading: Remove spent or faded flower plumes to encourage the plant to produce new side shoots and extend the blooming season.
  • Pinching: Pinch back the center stem of young plants to promote a bushier habit and more flower heads.
  • Air Circulation: Thin out overly dense foliage to improve airflow and prevent powdery mildew.
