Troubleshooting
Hamilton's Sundew problems — and how to fix them
Hamilton's Sundew (Drosera hamiltonii) 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.
Blackening and dying leaves
Almost always caused by tap water minerals or fertiliser residue. Switch immediately to distilled or rainwater and flush the pot thoroughly. Affected leaves will die back but healthy new growth should emerge.
Loss of sticky dew on tentacles
Indicates insufficient light or excessively low humidity. Move to a brighter spot or supplement with a grow light. The glands produce mucilage in response to adequate photosynthesis.
Crown rot
Caused by poor air circulation or standing water in the crown. Ensure good ventilation and keep water in the tray below the crown level. Remove any dead leaves promptly to prevent fungal spread.
