Cultivation & Care

Light Requirements

  • Bright, indirect light conditions that mimic the dappled sunlight of a forest floor

Watering & Humidity

  • Feeding once a month with a balanced, diluted fertilizer supports steady growth and vigor

Propagation Methods

Division and Cuttings

  • Most successfully achieved through division of the plant’s rhizomes
  • Ensure each division includes a portion of both roots and emerging shoots to promote healthy regrowth.

Seeds
