Care Guide

Watering

Keep soil consistently moist but not waterlogged; water early in the morning to minimize fungal disease risk

Fertilization

Apply diluted balanced liquid fertilizer every 2 weeks to support vegetative growth. Discontinue fertilization once flowering slows to prevent excessive foliage growth over blooms

Banana peel liquid fertilizer:Chop 2–3 banana peels and soak in 1 liter of water for 3 days; strain the liquid, dilute 1:1 with fresh water, and apply directly to the soil around the base of the plant
Pruning
  • Deadhead spent blooms regularly by cutting just above a leaf node to encourage continuous flowering
  • Pinch back young stem tips when plants reach 10–15 cm tall to promote bushier growth and more flower stems
  • Remove yellowing or damaged leaves to maintain plant health and improve air circulation
