Care Guide

Watering

Keep the substrate consistently wet, ideally using the tray method with distilled or reverse osmosis water.

Fertilization

Do not use traditional soil fertilizers; allow the plant to catch ambient fungus gnats.. Carnivorous plants derive nutrients from trapped insects. Soil fertilizers will burn their sensitive roots.

Pruning
  • Remove dead or decaying leaves at the base of the rosette to prevent fungal issues.
  • Snip off spent flower stalks near the base to conserve the plant's energy.
  • Do not trim healthy leaves, even if they are covered in digested insects, as they still photosynthesize.
⚠️
