Troubleshooting
Derby Sundew problems — and how to fix them
Derby Sundew (Drosera derbyensis) 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.
Crown and rhizome rot
The most common cause of plant death in cultivation. Cool temperatures combined with wet soil destroy the rhizome within weeks. Ensure the minimum temperature stays above 18 °C and drastically reduce watering as soon as the plant begins its rest phase.
Poor trap activity and insufficient dew
Leaves producing little or no mucilage indicate stress from low humidity, inadequate light, or compacted or degraded growing media. Refresh the soil mix annually, maximise light, and raise humidity to at least 60% during active growth.
