Care Guide

Watering

Maintain a 1–2 cm deep standing water tray beneath the container to keep soil saturated

Fertilization

No fertilization required; nutrients are obtained from captured insects. Avoid all fertilizers, as they can burn the sensitive root system of carnivorous plants

Not recommended:Carnivorous plants derive all necessary nutrients from trapped insects; any fertilizer application will damage or kill the plant
Pruning
  • Remove dead or brown pitcher leaves in late winter to improve airflow and maintain a tidy appearance
  • Trim spent flower stalks after blooming to redirect energy to new foliage growth
  • Divide overcrowded clumps every 3–5 years in early spring to promote healthy growth
