Quelch's Bladderwort problems — and how to fix them
Quelch's Bladderwort (Utricularia quelchii) 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.
Heat stress from temperatures above 28°C
This high-altitude species cannot tolerate warm indoor temperatures typical of lowland homes in summer. Above 28°C growth stalls and leaves yellow; move to a cool basement, greenhouse, or air-conditioned space, targeting daytime maxima below 25°C.
Sphagnum degradation and root suffocation
Long-fibre sphagnum breaks down over 1–2 years, compacting and turning anaerobic. Repot into fresh sphagnum annually to prevent root and stolon rot from the decomposing medium.
