Troubleshooting
Drosera Filiformis problems — and how to fix them
Drosera Filiformis (Drosera filiformis) 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.
Green, floppy, dewless leaves
Not enough light. Move to full sun or strong grow lights; sundews need intense light to redden and stay sticky.
Leaves dying back in autumn
Normal dormancy — it forms a hibernaculum and rests over winter. Keep it cool and just damp; new leaves emerge in spring.
Slow decline and loss of dew
Hard tap water or fertiliser contamination. Switch to rain/distilled water, flush the medium, and repot into fresh peat-sand mix.
Failure to return after winter
Either it was kept too warm and skipped dormancy, or dried out completely. Provide a genuine cool winter rest while keeping the medium damp.
