Troubleshooting
fairy aprons problems — and how to fix them
fairy aprons (Utricularia dichotoma) 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.
Failure to flower
Most often caused by insufficient light or overly short day length. Ensure at least 12–14 hours of bright light daily during the growing season. Some populations also benefit from a cooler winter period (10–15°C) to initiate flowering.
Algae and moss overgrowth on media surface
The permanently wet, bright conditions ideal for this plant also encourage algae and moss growth on the soil surface. These will not directly harm the plant but can outcompete it for space. Remove by hand or use black pot covers to block light from the media surface.
Disappearing plant
U. dichotoma periodically retreats entirely underground during cooler or drier periods, appearing to have died. Do not discard the pot — keep the media moist and the plant will re-emerge from dormant stolons when conditions improve.
