Care Guide

Watering

Keep soil consistently moist but not waterlogged; increase frequency during prolonged hot, dry periods

Fertilization

Apply diluted balanced liquid fertilizer every 2 weeks. Avoid fertilizing in autumn and winter when growth slows to prevent nutrient buildup in the soil

Banana peel compost tea:Soak fully composted banana peels in water for 3 days; dilute the tea at a 1:20 ratio with water before applying as a root drench; do not use raw peels to avoid attracting pests
Pruning
  • Deadhead spent flower clusters regularly to encourage continuous blooming throughout the flowering season
  • Prune overgrown or leggy branches in early spring to maintain a compact, rounded shape and promote new growth
  • Remove yellowing, damaged, or diseased leaves promptly to improve airflow and reduce the risk of fungal infections
  • Trim back up to one-third of the plant’s height in late winter to stimulate vigorous new growth for the upcoming season
