The Venus flytrap is a carnivorous plant native to the temperate and subtropical wetlands of North Carolina and South Carolina, on the East Coast of the United States. Although various modern hybrids have been created in cultivation, D. Wikipedia, CC BY-SA 4.0
Native range: E. North Carolina to E. South Carolina (subtropical). Also sold as Meadow Clams, Venus' fly trap and Venus' mouse trap.

How this shows up on a Venus flytrap
A thin dry rim that crumbles between the fingers
A narrow dry border on the Venus flytrap, often with a faint yellow line against the healthy tissue. It appears on several leaves at once rather than spreading from one.
Heated air holds less water than the plant loses into it, so moisture leaves the leaf faster than it arrives. Penn State Extension cites ASHRAE's indoor range of 30% to 60% relative humidity, and winter heating often takes a room below it. That applies while it is grown indoors; its RHS rating of H3 describes a plant that also grows outside, where the air is seldom that dry.
Telling it apart: Look at the pot rim and the soil surface. A white crust points at a build-up from tap water or feed rather than at the air. Penn State also reports misting and pebble trays do little to the humidity around a plant.

Colour goes before shape on a Venus flytrap. The outer leaves yellow evenly, stay soft to the touch, and the compost two inches down is still wet from the last watering.
The source for this plant describes moist but well-drained soil. Compost that stays saturated loses the air spaces fine roots grow into, and those roots die back first.
Telling it apart: Weigh the pot in your hand. A pot still heavy a week after watering is holding more water than the roots are using.

Most likely not enough light
- Full sun, Partial shade RHS · read 13 September 2026
Why: Far from a bright window, a venus flytrap builds leaves it cannot afford.
What to try:
- Move it closer to the brightest window you have, over a week or two rather than in one step.Useful: grow light
- Water less while it is in low light; a venus flytrap that is barely growing uses little.
What would settle it: Compare a new leaf with one from last year. Smaller and paler, with a longer gap below it, is the reaching pattern rather than a nutrient one.
Possibly its natural habit, or heat
Why: Close to a south window, light is seldom short, so stretching there is less likely to be reaching.
What to try:
- Turn the pot a quarter-turn each week and see whether the lean follows the window.
- Pinch out the growing tips to encourage bushier growth, if the venus flytrap is one that branches.
What would settle it: Whether it leans. A venus flytrap reaching for light bends toward the window; one growing to its habit, or growing fast in warmth, does not favour a side.
Possibly a lamp that is too far away or too weak
- Full sun, Partial shade RHS · read 13 September 2026
Why: The light a lamp delivers falls away quickly with distance, so a venus flytrap a little further from the lamp than intended gets much less.
What to try:
- Check the manufacturer's recommended distance for the lamp and measure it.
- Use a lamp made for growing plants rather than an ordinary household bulb.
What would settle it: Whether the growth nearest the lamp is more compact than the growth further away. A difference down the venus flytrap is a distance problem.
Less likely for a Venus flytrap, still possible

What this does not cover
This page orders a decision tree's results using a plant's sourced care. It has not seen your plant, its pot or its window, and two problems at once are common: that is the usual reason a confident answer turns out wrong. The questions in the diagnosis tool narrow it further than a list can.
