Venus Flytrap Leaf Burn vs. Fungus: Diagnosis and Care

A grower in Hungary sees brown areas on flytrap leaves and was told it's an internal fungus requiring fungicide. The plants grow outdoors in full sun, sitting in a water tray.

Not Fungus – It's Leaf Burn

The brown patches are typical leaf burn on older traps that developed in low light and high humidity (common in store-bought "death cubes"). The solution is simple: trim off affected leaves, keep the plant in full sun, and allow new, stockier, redder growth to emerge. Do not move it back to shade – the red interior color of traps indicates good health.

Patience yields a strong, healthy plant.
