Venus Flytrap Leaves Turning Brown—Normal or Problem?

Stella in Winston-Salem, NC, notices her outdoor Venus flytrap's leaves turning brown then black. She uses the nursery's potting mix.

Likely Normal Seasonal Cycling

Jeff Dallas asks: "Is it the older leaves at the base of the plant turning brown? If it is then this is normal. Venus flytraps, just like any plant, cycle through leaves during the growing season. In October most of the leaves will blacken and die as the plant approaches dormancy."

When to Worry

If newer leaves (center of rosette) are declining, something else is wrong—likely water quality, pests, or cultural issues. In that case, send a photo for diagnosis.

For now, assume it's natural leaf turnover. Keep the plant in full sun, sitting in pure water, and let nature take its course.
