1. Reveal & Reseal (Day 0)
Remove the vermiculite topper so the dewy leaves and soil surface are visible. Once exposed, close the lid again to maintain humidity.
2. High Humidity (Days 0–7)
Keep the lid fully closed and the cup upright. Place the plant in bright filtered light or under a 5000–6500 K LED grow light for about 12 hours per day.
Avoid direct midday sun while the lid is on, as the cup can overheat and dry out the dew.
3. Watering
Use only rainwater, RO water, or distilled water.
Stand the cup in 3–5 mm of water so the substrate stays evenly moist. Do not pour water over the leaves.
4. Vent & Harden (Days 8–21)
Gradually acclimate the plant to normal humidity:
- Days 8–14: Crack the lid open about 2–3 mm.
- Days 15–21: Remove the lid for 30 minutes longer each day.
- Day 22+: Remove the lid permanently once the leaves remain sticky and dewy.
5. Transplant (Week 4–6)
Move the plant into a 7 cm pot using a classic Drosera soil mix:
- 1/3 peat
- 1/3 perlite
- 1/3 silica sand
Keep the crown of the plant just above the soil surface. After transplanting, place the pot inside a bag or humidity dome for about 7 days, gradually venting it open.
6. Feeding
Once hardened, the plant will naturally catch small insects.
Indoors you can occasionally feed:
- One small crushed insect or bloodworm
- Every 2–4 weeks
- Apply to one leaf only
Do not fertilise the soil.
Core Growing EssentialsWater Quality
Use distilled, rain, or RO water only. Minerals found in tap water can suppress dew production and damage the plant.
Lighting
- Subtropical and tropical Drosera: bright indirect light or gentle morning sun.
- Temperate and South African species: at least 6 hours of direct sunlight or strong LEDs positioned 15–25 cm above the plant for 12–14 hours daily.
Humidity
Humidity between 50–80% helps maintain sticky dew. Some hardy species can adapt to lower humidity once mature.
Temperature
- Tropical species: 20–30°C year-round.
-
Temperate species:
- Summer: 15–25°C
- Winter dormancy: 0–10°C for 3–4 months
Soil
Drosera prefer acidic, nutrient-poor soil composed of peat, perlite, and silica sand. Avoid fertilisers, compost, or nutrient-rich mixes.
Watering Method
Keep the soil consistently moist. The tray method works best.
During dormancy, reduce the water level so the soil remains slightly damp rather than wet.
Airflow
Provide gentle air movement. This reduces mould and fungal issues while maintaining humidity.
Pests
Watch for aphids, fungus gnats, and mites. Treat with insecticidal soap or neem oil if necessary.
Containers
Use plastic or glazed pots, which prevent mineral build-up. Avoid unglazed terracotta or clay pots.
Patience
Sundews grow steadily. Strong colouration and large dew drops develop with stable light, pure water, and consistent conditions.
Troubleshooting Guide| Symptom | Likely Cause | Remedy |
|---|---|---|
| No dew or sticky drops | Low humidity or insufficient light | Increase humidity to at least 50% and provide brighter light |
| Brown leaf tips | Sunburn or dry wind | Provide filtered light and protect from hot drafts |
| Blackening leaves after transplant | Fungal infection or humidity shock | Maintain high humidity, treat with fungicide, remove affected leaves |
| Yellow leaves | Mineral burn from tap water | Flush pot with pure water and avoid tap water |
| Leaves curling or distorted | Aphids or mites | Inspect closely and treat with insecticidal soap or neem |
| White fuzzy mould | Stagnant air and excess moisture | Improve airflow and allow surface to dry slightly before refilling the tray |
| Plant browning in winter | Entering dormancy (temperate species) | Reduce watering and keep cool (0–10°C) until spring |
| Slow growth | Low light or lack of prey | Increase light levels and feed a small insect occasionally |
| Root rot or foul smell | Waterlogged soil | Repot into fresh airy mix and allow the tray to dry briefly before refilling |
