Care Guide

Watering

Keep soil consistently moist; water when the top 2 cm of soil feels dry

Fertilization

Feed every 2 weeks with balanced diluted liquid fertilizer. Avoid over-fertilizing to prevent leggy growth and reduced blooming

Banana peel tea:Chop 2–3 banana peels, soak in 1 liter of water for 3 days, strain, and dilute 1:10 with water for root drenching to boost bloom production
Pruning
  • Deadhead spent blooms regularly to encourage continuous flowering throughout the growing season
  • Trim back leggy stems by one-third in mid-summer to promote bushier, more compact growth
  • Cut back foliage to basal rosettes after flowering to prepare the plant for winter dormancy
  • Remove yellowing or damaged leaves to improve airflow and reduce disease risk
