Care Guide

Watering

Water thoroughly when the top 1-2 inches of the soil mix feels dry.

Fertilization

Apply a balanced, water-soluble fertilizer diluted to half strength.. Fertilize only during the active growing season. Flush the soil periodically to prevent salt accumulation.

Aquarium Water:Use untreated water from routine freshwater aquarium changes. It provides a gentle, organic source of nitrogen and beneficial microbes. Ensure the water contains no added aquarium salts or medications.
Pruning
  • Remove older, yellowing, or damaged leaves at the base of the petiole using sterilized shears;
  • Wipe the large velvety leaves gently with a damp microfiber cloth to remove dust and support photosynthesis;
  • Trim away any dead or rotting aerial roots, but leave healthy ones intact or guide them into the soil.
