What is eating my lesser bladderwort?
Lesser Bladderwort (Utricularia minor) is a small aquatic carnivorous houseplant grown submerged or in shallow bog trays. Its bladder traps feed on tiny aquatic organisms. Pest threats are minimal compared to other houseplants. Algae overgrowth is the most common problem, and fungus gnats breed in saturated surface media. Pure water and bright light are the best controls.
