Reviving Stressed Venus Flytraps: Repotting, Light, and Leaf Pruning

Diagnosing the Problem

A grower in the Pacific Northwest purchased two Venus flytraps (a typical green and a 'Red Dragon') three weeks ago. They were sold in pots with clear plastic humidity domes. After removing the domes and placing the plants outside on a south-facing patio, the plants showed stress due to cool, overcast weather. The grower moved them indoors to a south-facing window, but the soil remains soggy, and both plants look poor, especially the Red Dragon.

Immediate Action Plan

1. Repot into proper media: Use a 50/50 mix of peat moss (from a bale, not small bags which may contain fertilizer) and perlite or clean sand. Fertilizer is toxic to carnivorous plants. Use a 5–8 inch pot.
2. Inspect rhizomes: They should be white and firm. Brown, mushy rhizomes indicate the plant is dead.
3. Provide full sun and constant moisture: Place the pot in a shallow tray of water in a location with full sun (enough to grow tomatoes). Keep the tray filled so the soil never dries out.
4. Cut off all existing leaves: Leaves weakened by humidity domes rarely recover. Removing them down to the soil surface forces strong, healthy new growth within about a month.
