Troubleshooting
Utricularia subulata problems — and how to fix them
Utricularia subulata (Utricularia subulata) 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.
Drying out
Even brief drought kills the delicate stolons; keep the medium permanently saturated using the tray method.
Algae and moss overgrowth
In nutrient-rich or stagnant conditions algae and liverworts smother the tiny plant; use clean nutrient-free water and bright light.
Poor flowering
Too little light produces foliage but few of the characteristic yellow flowers; give it bright light to full sun.
Spreading into other pots
Its fine stolons readily colonise neighbouring carnivorous-plant pots; manage by isolating containers if you want to contain it.
