Sarracenia purpurea Holes, Leaf Arrangement, and VFT Trap Death After Feeding

Three Common Carnivorous Plant Questions Answered

A grower asked: (1) Neat holes in S. purpurea leaves—sun magnification, insects escaping? (2) New leaves grow in all directions after tight rosette—where do they go? (3) VFT traps turn black/rot after catching real prey—why?

Expert Answers (Jeff Dallas)

1. Holes: Not sunburn (irregular). Likely insect chewing—check for worms/grubs in/on pitchers.
2. Leaf arrangement: Mature purpurea forms tight masses. Winter: trim dead leaves to open crown. Divide every few years (early spring) to prevent Botrytis in crowded crowns.
3. VFT trap death after feeding: Digestion requires energy (enzymes). Prey provides nutrients, not energy. Insufficient sun = traps rot before digestion completes. Most common cause: inadequate light.
