Care Guide

Watering

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

Fertilization

Diluted balanced liquid feed once every 4 weeks. Avoid over-fertilizing, as it prefers low-nutrient woodland conditions

Banana peel compost tea:Compost banana peels for 2 weeks, steep in water at a 1:20 ratio, and apply as a root drench to support flower production without overfeeding
Pruning
  • Deadhead spent flower heads to prevent unwanted self-seeding if desired
  • Cut back all foliage to ground level in late autumn to prepare for winter dormancy
  • Thin overcrowded clumps in early spring to improve airflow and reduce disease risk
