Dionaea muscipula 'Red Dragon' (Red Dragon Venus Flytrap) care

Light

Aim for at least 4-6 hours of direct sun on the leaves. Wants full, direct sun (4-6+ hours) or a very strong grow light; intense light is what develops the signature all-over red colour, and shade leaves it green and weak. If your only bright window faces south, that's perfect for dionaea muscipula 'red dragon' — same window any aroid would fry on.

Watering

Watering dionaea muscipula 'red dragon': keep constantly moist; tray-water with pure water. 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. Stand the pot in 1-2 cm of rain, distilled or RO water during the growing season, letting it run a touch drier in winter dormancy. Tap or mineral water kills flytraps.

Soil and pot

Dionaea muscipula 'Red Dragon' grows best in nutrient-free peat and sand carnivorous mix. Use a 1:1 (or peat-heavy) blend of sphagnum peat with silica sand or perlite. No fertiliser, compost, lime or ordinary potting soil. 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

Dionaea muscipula 'Red Dragon' sits happiest at around 40-60% humidity and 21-35°C summer; 0-10°C winter dormancy (70-95°F summer; 32-50°F winter dormancy). Adapts well to ordinary household humidity and does not need a terrarium; good airflow helps prevent fungal problems on the traps. If you keep the room above 21 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 dionaea muscipula 'red dragon' sparingly. Never fertilise the roots. It feeds by catching insects; if grown bug-free indoors, drop a small live or rehydrated insect into an active trap every few weeks during the growing season. Do not feed during dormancy. 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 dionaea muscipula 'red dragon' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Skipping winter dormancy — Kept warm and growing year-round it exhausts itself and dies; give a cold 3-4 month dormancy with reduced light and water.
• Triggering traps for fun — Repeatedly making traps snap without prey wastes the plant's energy and blackens the traps; leave them alone.
• Mineral water death — Tap or bottled mineral water poisons flytraps within weeks; use only rain, distilled or RO water.
• Loss of red colour — Insufficient light turns 'Red Dragon' green; only strong direct light produces the deep maroon pigmentation.

Propagation

Rhizome division of clumps in late winter, leaf-pullings (whole leaves with a sliver of white rhizome) set in damp medium, or flower-stalk cuttings; seed is slow and 'Red Dragon' is kept true by vegetative means. 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

Dionaea muscipula 'Red Dragon' is pet-safe. ASPCA-listed as non-toxic to dogs, cats and horses (Venus Fly Trap, Dionaea muscipula). Chewing may cause at most mild gastrointestinal upset, and there is no toxic principle; the main risk is to the fragile plant rather than the pet. 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.
