Hen-and-Chickens Sundew problems — and how to fix them
Hen-and-Chickens Sundew (Drosera prolifera) 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.
Leaf browning and plant decline
Almost always humidity collapse — even brief drops below 70% damage this species. Ensure the terrarium lid is firmly closed and mist the interior walls (not the plant) if humidity readings drop. No other sundew is quite so unforgiving of low humidity.
Algae and fungal growth in terrarium
High humidity combined with poor air circulation promotes algae on the soil surface and Botrytis on leaves. Introduce a small fan to provide gentle air movement, and remove dead plant material promptly.
Scape plantlets failing to root
Plantlets form readily on the scapes but can fail to root if pressed against dry substrate. Pin the scape gently against moist sphagnum with a small clip or wire staple; plantlets root within 3–5 weeks and can then be severed and potted individually.
