Care Guide

Watering

Keep soil evenly moist, watering when the surface feels slightly dry to the touch.

Fertilization

Apply a balanced liquid fertilizer diluted to half strength to encourage foliage growth.. Fertilize only during the active growing season; stop feeding in late summer as the plant prepares for dormancy.

Banana Peel Tea:Steep chopped banana peels in water for 24-48 hours. Dilute 1:1 with water and apply to soil to boost tuber health and leaf color. Discard solids in compost to avoid attracting pests or mold.
Pruning
  • Remove yellowing, drooping, or dead leaves at the base to maintain a tidy appearance and prevent fungal issues;
  • Cut off any flower stalks (spathes) as soon as they appear to redirect the plant's energy back to foliage production;
  • Before winter dormancy, trim back all withered foliage once it dies back naturally.
