Long-Stalked Bladderwort problems — and how to fix them
Long-Stalked Bladderwort (Utricularia praelonga) 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.
Substrate drying out
U. praelonga is highly sensitive to desiccation — even a few days without water in summer can kill the fine stolons. A permanent shallow water tray is the most reliable safeguard; never rely on top-watering alone.
Algae overgrowth in the water tray
Bright light plus standing water encourages algal growth that can smother the small terrestrial plant. Change the saucer water weekly and keep the water tray clean; avoid direct sun on the water surface.
