Care Guide

Watering

Keep soil consistently moist but not waterlogged; water early in the day to minimize fungal growth on foliage

Fertilization

Diluted balanced liquid fertilizer every 2 weeks. Avoid over-fertilization, which can lead to lush foliage but reduced flowering

Banana peel compost tea:Compost banana peels for 2–3 weeks to break down nutrients; steep in water for 24 hours, dilute 1:20 for root drench; discard solid peels to avoid pest infestations
Pruning
  • Deadhead spent blooms regularly to encourage continuous flowering throughout the growing season
  • Pinch back young seedlings when 10–15 cm tall to promote bushier, more compact growth
  • Trim leggy stems mid-season to maintain a neat, upright habit and redirect energy to flower production
