Recurring Winter Rot in Venus Flytraps and Sarracenia

Robert in Portland lost many Venus flytraps and some Sarracenia to rot over three winters despite adjusting water levels and using sulfur fungicide. This year, a 'Colorado Giant' flytrap in a 3-inch pot rotted (brown bulb). Plants were left outdoors per advice (no garage). Asks if outdoor exposure caused the problem.

Expert Analysis: Microclimate Suspected

Jeff Dallas suspects microclimate issues: areas near houses can stay colder, be more prone to fungus, or have wind chill causing dehydration. He notes the flytrap was in a small pot—larger pots help buffer conditions. He requests photos of the growing area to diagnose further and offers a phone consultation.

Good Growing!
