Shark Teeth Venus flytrap (Shark Teeth flytrap) care

Light

Aim for at least 4-6 hours of direct sun on the leaves. Requires 4–6 hours or more of direct sunlight daily for the blood-red upper trap surfaces to develop fully. South-facing windows or outdoor summer placement is ideal. Under grow lights, provide full-spectrum LED at 14–16 hours per day positioned close to the foliage. If your only bright window faces south, that's perfect for shark teeth venus flytrap — same window any aroid would fry on.

Watering

Watering shark teeth venus flytrap: continuously moist via tray watering; slightly drier in winter. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Keep the pot standing in 2–4 cm of distilled, rainwater, or RO water throughout the growing season. Reduce to barely damp during dormancy (October–March). Tap water minerals accumulate and kill plants — use only pure water.

Soil and pot

Shark Teeth Venus flytrap grows best in nutrient-poor acidic carnivore mix. A 1:1 blend of long-fibre sphagnum moss and horticultural perlite is ideal. Alternatively use pure peat-free sphagnum. Absolutely no compost, potting mix, or fertiliser additives — dissolved minerals are lethal. Repot annually in spring. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Shark Teeth Venus flytrap sits happiest at around 50–80% humidity and 5–35°C (growing season 18–30°C; dormancy 2–10°C) (41–95°F (growing season 64–86°F; dormancy 36–50°F)). Tolerates typical household humidity when roots are kept wet, but thrives at 60–80%. Placing the tray of water nearby provides passive humidity. A terrarium or cloche helps in centrally heated rooms below 50% RH. If you keep the room above 5–35°C (growing season 18–30°C; dormancy 2–10°C) year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed shark teeth venus flytrap sparingly. No soil fertiliser. Feed by allowing the plant to trap small live or freeze-dried insects — one insect per trap every 4–6 weeks during the growing season. Avoid feeding in dormancy. Never apply liquid or granular fertilisers. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on shark teeth venus flytrap in the Growli community. Each is annotated with the most common cause so you know where to start.

• 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.

Propagation

Division of rhizome offsets in spring; leaf-pullings (detach a leaf with white rhizome tissue attached, lay flat on damp sphagnum at 20–25°C in high humidity). Seeds do not produce cultivar-true offspring — vegetative propagation only to maintain 'Shark Teeth' characteristics. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Shark Teeth Venus flytrap is pet-safe. ASPCA lists Dionaea muscipula (Venus fly trap) as non-toxic to cats, dogs, and horses. No toxic principles are known in this species. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
