Care Guide

Watering

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

Fertilization

Apply balanced liquid fertilizer every 2 weeks to support foliage and flower growth. Avoid over-fertilizing, as this can reduce foliage color intensity

Banana peel compost tea:Compost banana peels for 2 weeks, steep in water for 24 hours, dilute 1:20 with water for root drenching to support flower production
Pruning
  • Deadhead spent flower stalks promptly to encourage continuous blooming throughout the season
  • Cut back all aboveground foliage to ground level after the first frost in cool climates to prepare for winter dormancy
  • Thin overcrowded clumps in early spring to improve airflow and reduce disease risk
