Short-Horned Sundew problems — and how to fix them
Short-Horned Sundew (Drosera brevicornis) 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 rot
Caused by poor air circulation combined with standing water touching the crown; ensure airflow around the plant and keep the tray water below crown level.
Loss of dew on tentacles
