About Alice's Sundew
Drosera aliciae · also called Alice's sundew, Alice sundew · houseplant
Alice's sundew is a compact, carnivorous rosette from South Africa's Cape, prized for spoon-shaped leaves studded with glistening, insect-trapping tentacles. It is one of the easiest sundews indoors: give it bright light, mineral-free water by the tray method, and lean peat-sand soil. ASPCA does not list it, so treat as mildly toxic and verify with your vet.
Ideal humidity: 50-60%
Watch for — Browning leaves or sudden dieback: Most often mineral damage from tap or bottled mineral water, or fertiliser in the soil. Switch to rain/distilled water (under 50 ppm TDS) and repot into a nutrient-free peat-sand mix.
The watering schedule, season by season
Alice's 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 alice's sundew is keep soil constantly damp; tray topped up year-round, easing off slightly 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.
Use only rain, distilled, or reverse-osmosis water (TDS under 50 ppm) — tap-water minerals will kill it. Stand the pot in a 1-2 cm tray of water (the tray method) and refill before it runs dry. Alice's sundew tolerates a little more dryness than most sundews but never let the media fully dry out.

How to tell alice's sundew needs water
A calendar is the worst way to water alice's 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 alice's sundew for a day is almost always safer than over-watering it.
Overwatering vs underwatering alice's sundew
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For alice's 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 alice's 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 alice's sundew.
Seasonal and environmental adjusters
Every figure above shifts with the conditions in your home. For alice's 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 alice's sundew.

How do I know when alice's 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 alice's 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 alice's 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 alice's sundew. Its roots cannot handle dissolved minerals — only rain, distilled, or reverse-osmosis water will do.
