Care Guide

Watering

Maintain consistent soil moisture using tray watering to boost humidity

Fertilization

No fertilizer required; obtains nutrients from captured insects. Standard plant fertilizers will burn the delicate root system and harm the plant

Dechlorinated aquarium water runoff:Use only dechlorinated water; dilute 1:20 with distilled water to avoid nutrient overload; apply as a soil drench sparingly
Pruning
  • Remove dead, brown leaves to maintain rosette appearance and reduce mold risk
  • Trim spent flower stalks after blooming to redirect energy to leaf growth
  • Thin overcrowded rosettes in spring to encourage new offshoot development
