Care Guide

Watering

Keep soil consistently moist but not waterlogged; increase watering frequency during hot, dry spells

Fertilization

Diluted balanced liquid fertilizer every 2 weeks. Avoid over-fertilizing, as excessive nitrogen can reduce flower production

Banana peel compost tea:Use fully composted banana peels to avoid odor and pest issues; steep peels in water for 3 days, dilute 1:20 for root drenching
Pruning
  • Remove spent blooms promptly to encourage continuous flowering throughout the growing season
  • Thin overcrowded branches to improve airflow and reduce risk of fungal disease
  • Prune back to 1–2 m in late winter to maintain a compact, manageable shape
  • Remove dead, diseased, or damaged stems to prevent spread of pathogens
