About Pygmy Sundew
Drosera scorpioides · also called pygmy sundew, scorpion sundew · houseplant
Drosera scorpioides is a tiny Western Australian pygmy sundew forming a stalked rosette of dew-tipped tentacled leaves that glisten and catch small insects. It thrives in bright light, pure water, and lean acidic soil, and is famous for propagating from gemmae, tiny clonal buds it produces in cooler months. Compact and rewarding, it is pet-safe.
Ideal humidity: 50-70%
Watch for — Loss of dew: Tentacles with no sticky droplets usually mean light is too low, humidity too low, or air too dry from heating. Increase light and humidity, and keep the tray topped up with pure water.
The watering schedule, season by season
Pygmy Sundew 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 pygmy sundew is keep soil moist via a shallow tray; top up as it dries, 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.
Use the tray method with a thin layer of water so the soil stays moist but not deeply waterlogged; pygmy sundews dislike being permanently flooded. Use ONLY rainwater, distilled, or reverse-osmosis water. Ease back slightly in the cooler gemmae season, but never let the small plants dry out completely.

How to tell pygmy sundew needs water
A calendar is the worst way to water pygmy sundew. 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 pygmy sundew for a day is almost always safer than over-watering it.
Overwatering vs underwatering pygmy sundew
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For pygmy sundew 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 pygmy sundew. 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 pygmy sundew.
Seasonal and environmental adjusters
Every figure above shifts with the conditions in your home. For pygmy sundew, 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 pygmy sundew.
Pygmy Sundew watering — frequently asked questions
How often should I water pygmy sundew?
Water pygmy sundew keep soil moist via a shallow tray; top up as it dries. 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. Winter: keep just damp, not flooded — many temperate carnivores need a cool dormancy with far less water.
How do I know when pygmy sundew needs water?
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 single most reliable test for pygmy sundew is the first signal on that list — checking the soil or the plant directly always beats watering by the calendar.
What does an overwatered pygmy sundew look like?
Blackening traps or pitchers from stagnant, warm, mineral-laden water. Rotting crown if kept warm and flooded through winter dormancy. Tap or bottled mineral water kills pygmy sundew. Its roots cannot handle dissolved minerals — only rain, distilled, or reverse-osmosis water will do.
What are the signs of an underwatered pygmy sundew?
Traps go limp and brown; pitchers dry up. The medium dries out and the plant collapses quickly.
Can I use tap water on pygmy sundew?
Only rainwater, distilled or reverse-osmosis water — never tap, mineral or softened water. This is the single most important rule for pygmy sundew.
