Shark Teeth Venus flytrap problems — and how to fix them
Shark Teeth Venus flytrap (Dionaea muscipula 'Shark Teeth') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Traps lose red coloration
Inadequate direct sunlight prevents anthocyanin pigment development. Increase light exposure — outdoors in summer or directly under a grow light. Shade or low light results in fully green traps with reduced trapping efficiency.
Browning leaf tips or trap edges
Usually caused by tap water minerals or fluoride. Switch immediately to distilled, rainwater, or reverse-osmosis water. Also check that the pot is not sitting in water so deep that the rhizome rots — 2–4 cm is sufficient.
Weak growth despite good conditions
Often a skipped or inadequate dormancy. Ensure 2–4 months of cool rest at 2–10°C with reduced watering. Plants denied dormancy exhaust energy reserves and decline over 1–2 growing seasons.
