Falconer's Sundew problems — and how to fix them
Falconer's Sundew (Drosera falconeri) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Leaf collapse and flattening without dew
Broad leaves with poor mucilage production indicate heat stress, low humidity, or root problems. Check that soil is consistently moist during the growing season, raise humidity above 65%, and verify the growing temperature exceeds 25 °C.
Rhizome failure during dry season
D. falconeri is particularly sensitive to cool-damp conditions in dormancy — the combination kills the rhizome quickly. Keep minimum temperatures at 18 °C and reduce water to the absolute minimum needed to prevent desiccation during rest.
