About Shark Teeth Venus flytrap
Dionaea muscipula 'Shark Teeth' · also called Shark Teeth Venus flytrap, Shark Teeth flytrap · houseplant
A collector cultivar whose trap lobes are lined with broad, triangular, shark-fin teeth without serrations — giving the open trap the unmistakable look of a gaping shark jaw. Grows erect in summer, prostrate during winter dormancy. Like all Venus flytraps, it demands pure water, full sun, and nutrient-poor soil. Pet-safe per ASPCA.
Ideal humidity: 50–80%
Watch for — 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.
The watering schedule, season by season
Shark Teeth Venus flytrap is a bog plant adapted to nutrient-poor wet ground — it must sit in a tray of pure water and must never get tap water or fertiliser. The base rhythm for shark teeth venus flytrap is continuously moist via tray watering; slightly drier in winter, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.
- Spring & summer (active growth): Spring and summer: keep the pot standing in 1-2 cm of distilled or rainwater at all times; top the tray up as it is taken up.
- Autumn (slowing down): Autumn: lower the tray water level as growth slows and (for temperate species) dormancy approaches.
- Winter (rest / dormancy): Winter: keep just damp, not flooded — many temperate carnivores need a cool dormancy with far less water.
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.

How to tell shark teeth venus flytrap needs water
A calendar is the worst way to water shark teeth venus flytrap. Check the plant and the soil instead — for this species, look for these signals in order:
- The tray has run dry (during active growth it should rarely be empty).
- The peat-based medium feels dry rather than wet.
- Traps or pitchers shrivel or fail to form.
The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering shark teeth venus flytrap for a day is almost always safer than over-watering it.
Overwatering vs underwatering shark teeth venus flytrap
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For shark teeth venus flytrap specifically:
Signs you are overwatering
- Blackening traps or pitchers from stagnant, warm, mineral-laden water.
- Rotting crown if kept warm and flooded through winter dormancy.
Signs you are underwatering
- Traps go limp and brown; pitchers dry up.
- The medium dries out and the plant collapses quickly.
Tap or bottled mineral water kills shark teeth venus flytrap. Its roots cannot handle dissolved minerals — only rain, distilled, or reverse-osmosis water will do.
Water quality notes
Only rainwater, distilled or reverse-osmosis water — never tap, mineral or softened water. This is the single most important rule for shark teeth venus flytrap.
Seasonal and environmental adjusters
Every figure above shifts with the conditions in your home. For shark teeth venus flytrap, the levers that matter most are:
- Bright light plus the water tray is the whole game — no fertiliser ever goes in the soil.
- In hot weather the tray empties fast; check it daily.
- Temperate species need a cooler, drier winter dormancy, not constant flooding.
Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of shark teeth venus flytrap.
Shark Teeth Venus flytrap watering — frequently asked questions
