Care Guide

Watering

Fertilization

Apply diluted balanced liquid feed once monthly. Avoid over-fertilizing, as this can reduce flower production

Banana peel infusion:Steep 1 peeled banana in 4 liters of water for 24 hours; dilute the infusion 1:2 with fresh water before applying to soil to avoid nutrient burn
Pruning
  • Deadhead spent blooms regularly to encourage continuous flowering throughout the growing season
  • Trim back leggy or overgrown stems in mid-summer to promote compact, dense growth
  • Remove yellow or damaged foliage to maintain plant health and improve airflow
