Venus Flytrap Leaves Turning Black: Dormancy or Rot?

Normal vs. Problematic Blackening

Older leaves naturally blacken and die, starting from the trap or petiole edges. If the central growing crown remains green and healthy, the plant is likely entering winter dormancy.

Proper Watering Technique

• Grow "moist, not wet"—avoid constant saturation to prevent rot.
• Top-watering with RO water (TDS < 50 ppm) is fine; allow excess to drain.
• Bottom-watering works if the tray is removed after absorption (20 min–2 hours).
• Let the medium dry to just moist before rewatering.
• Deeper pots (4–6 inches) benefit root development.

When to Worry

If blackening spreads rapidly or the crown discolors, suspect rot. Post photos on FlytrapCare Forum for expert diagnosis.
