Utricularia sandersonii problems — and how to fix them
Utricularia sandersonii (Utricularia sandersonii) 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.
Media drying out
The thin carpet desiccates quickly; keep the pot standing in mineral-free water at all times, especially in warm or dry rooms.
Mineral or tap-water damage
Hard water and fertilisers cause browning and dieback; flush only with rainwater, distilled or RO water and discard any nutrient-rich runoff.
Sparse flowering
Usually too little light or a stagnant temperature regime; increase brightness and allow a slight night-time dip to encourage repeat blooming.
Algae or liverwort on the surface
Wet, bright, nutrient-tinged media invites competitors; keep water lean, improve airflow and pick off liverwort before it smothers the carpet.
