Venus Flytrap problems & how to fix them

Dionaea muscipula

Drooping, yellowing, brown tips, or a plant that just won’t thrive? Here are the most common Venus Flytrap problems, what usually causes them, and how to turn things around.

Common problems

Fertilizer burn

Any potting fertilizer or mineral-rich water burns the roots of this bog specialist. Root and leaf damage from a buildup of fertilizer salts in the soil, usually after overfeeding. Burned leaf tissue will not recover, but flushing the soil stops further damage and most plants push healthy new growth within two to three weeks.

Etiolation (insufficient light)

Indoor shade produces long weak petioles and traps that won't close. The plant is stretching toward light it isn't getting: long gaps between leaves, pale thin growth, and leaning. Stretched growth never compacts again, but with more light all new growth comes in full and sturdy - the plant's future is good.

Underwatering

One full dry-out of the bog soil can kill the rhizome. The plant is not getting enough water, either from infrequent watering or soil so dry it repels water. Prognosis is excellent - most underwatered plants perk up within days of proper rehydration.

Root rot

Warm, stagnant, waterlogged conditions in winter rot the dormant rhizome. A fungal or bacterial infection of the roots, almost always triggered by soil staying wet too long. Caught early, most plants recover within a few weeks after repotting; if most roots are already mushy, recovery is uncertain.

The mistakes that most often kill it

Watering with tap or mineral water — the number one flytrap killer.
Skipping winter dormancy in a warm room until it exhausts itself, usually within two years.
Playing with the traps for fun; each false closure wastes serious energy.
