Fork-leaved Sundew problems — and how to fix them
Fork-leaved Sundew (Drosera binata) 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.
Tentacles stop producing dew
Almost always too little light or hard/tap water — move to direct sun and switch to rain/RO water.
Leaf tips browning and dying back
Mineral build-up from tap water or fertiliser, or the peat dried out. Flush with pure water and keep permanently wet.
Black, mushy crown
Crown rot from stagnant warm, enclosed conditions. Improve airflow and avoid sealing in a humid case.
Failure to go dormant or weak spring growth
Temperate forms benefit from a cool, brighter winter rest around 5-10°C; constant warmth can exhaust them.
