Beautiful Sundew problems — and how to fix them
Beautiful Sundew (Drosera venusta) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Poor or absent sticky mucilage
Most often caused by low light. Move to a brighter spot or extend artificial lighting to 14 hours. Low humidity can also reduce dew; increase with a humidity tray.
Root rot
Occurs when the medium becomes anaerobic, often from using unventilated pots or water that is too deep in the tray. Ensure the pot has drainage holes and limit tray water depth to 1-2 cm.
Aphid infestation on flower stalks
Aphids occasionally colonise flower scapes. Remove by hand or use a gentle spray of water; avoid chemical insecticides which can harm the plant.
