Care Guide

Watering

Water thoroughly when the top inch of soil feels dry to the touch.

Fertilization

Apply a diluted, balanced liquid houseplant fertilizer.. Do not fertilize during the winter months when the plant's growth naturally slows down.

Aquarium Water:Use dirty water from freshwater aquarium changes. It provides gentle, natural nitrogen without the risk of chemical burn. Ensure the water has no added salts or medications.
Pruning
  • Remove dead, brown, or yellowing leaves by cutting them at the base of the stem with sterilized shears;
  • Trim away crispy leaf edges if necessary, following the natural shape of the leaf;
  • Avoid heavy misting directly on the fuzzy leaves to prevent fungal or bacterial leaf spot; instead, use a humidifier.
