Care Guide

Watering

Maintain consistent moisture; mist regularly to boost humidity to 60–80%

Fertilization

Diluted carnivorous plant fertilizer applied once monthly. Avoid high-nitrogen fertilizers, as they can disrupt the plant's carnivorous nutrient uptake process.

Composted vegetable scrap tea:Use fully composted vegetable scraps steeped in water, diluted 1:50 to avoid over-fertilizing; apply only during active growth periods to prevent root damage.
Pruning
  • Trim dead or yellowing pitchers to improve air circulation and redirect energy to new growth.
  • Cut back overgrown climbing stems to encourage compact, bushy growth; healthy stem cuttings can be propagated.
  • Remove spent flower racemes after blooming to conserve the plant's energy for pitcher production.
