Caring for Drosera venusta, a beautiful subtropical sundew native to South Africa, is relatively straightforward if you meet its basic needs. Here’s a care guide to help it thrive:🌞

Light Requirements

Bright light to full sun is ideal. Provide at least 6 hours of direct sunlight per day or supplement with a grow light (6500K, 12–16 hours/day).
In lower light, the plant may lose its red coloration and grow weak.

💧

Watering

Keep the soil consistently moist, but not soggy.
Use the tray method: place the pot in a shallow tray of distilled, rain, or reverse osmosis water. Avoid tap water unless you know it’s very low in minerals (TDS < 50 ppm).
Never let it dry out completely.

Soil

Use a mix of peat moss (sphagnum peat) and perlite or silica sand in a 1:1 ratio.
Do not use compost, fertilizer, or standard potting mix — they can kill the plant.

🌡️

Temperature & Humidity

Prefers temperatures between 60–85°F (15–29°C).
Tolerates lower humidity better than many sundews but will do best with 40–70% humidity.
Can tolerate mild cold but should be protected from frost.

🌱

Feeding

Feeds on small insects like gnats or fruit flies.
If growing indoors and no bugs are around, you can feed it crushed dried bloodworms or betta fish pellets once or twice a month. Use tiny portions on a few leaves.
Do not fertilize the soil.

💤

Dormancy

Drosera venusta does not require dormancy and can grow year-round under stable conditions.
If it slows down in winter, reduce watering slightly, but keep moist.

🧽

Pest Issues

Watch out for aphids, fungus gnats, or mold. Good air circulation helps.
Avoid chemical pesticides — use neem oil cautiously, or better, manual removal or beneficial insects.

Repotting

Repot every 1–2 years to refresh the medium and prevent mineral buildup.
Use the same peat-based soil mix.
