Care Guide

Watering

Water regularly during active growth to support blooming; avoid overwatering to prevent root rot

Fertilization

Apply a light, balanced slow-release feed at the start of growing season. Avoid high-nitrogen fertilizers, which can reduce flower production

Banana peel tea:Soak 2–3 chopped banana peels in 1 liter of water for 24 hours; strain and water the base of plants to deliver potassium without chemical additives
Pruning
  • Deadhead spent blooms regularly to extend the flowering period
  • Cut back foliage to 10 cm above soil level after the first frost for winter tidiness
  • Thin overcrowded clumps every 2–3 years in early spring to improve airflow and reduce disease risk
