Fertilization

Diluted balanced liquid feed every 4 weeks. Discontinue fertilization in autumn as growth slows.

Banana peel compost tea:Steep fully composted banana peels in water for 24 hours; dilute 1:20 with water for root drenching to support tuber development.
Pruning
  • Trim yellowing or dead foliage at the base to maintain a tidy clump appearance.
  • Cut back spent flower stems after blooming to redirect energy to tuber production.
  • Thin overcrowded clumps in early spring to improve airflow and reduce competition for nutrients.
