Care Guide

Watering

Water generously as new growth appears, allowing the medium to nearly dry between waterings.

Fertilization

Apply a balanced, water-soluble fertilizer at quarter strength weekly.. Cease fertilization entirely during the autumn and winter rest period.

Banana Peel Tea:Steep chopped banana peels in water for 24-48 hours, strain, and dilute 1:1 with fresh water. Use during the active growing season to support strong canes and future blooms. Discard solids in compost to avoid attracting fungus gnats.
Pruning
  • Do not cut old canes: Even leafless, shriveled canes store energy and water, and can produce flowers or keikis (baby plants) in subsequent years;
  • Remove spent flowers: Snip off individual faded blooms to maintain a tidy appearance;
  • Trim dead roots: When repotting, use sterilized shears to remove mushy, brown, or hollow roots, leaving the firm white or green ones intact.
