Why does your Sinningia Empress White have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The presence of tiny black flies is most likely the larvae and adults of fungus gnats, which thrive in the moist, organic-rich soil required by Sinningia. They feed on decaying organic matter and can damage the delicate rhizomes of your Gloxinia if infestations become severe.
Sinningia species are highly susceptible to rot; if the substrate remains perpetually saturated, it creates the perfect breeding ground for fungus gnat larvae. This excess moisture also stresses the plant, making its roots more vulnerable to fungal pathogens.
Old, decomposing potting media or uncomposted bark in the Sinningia's mix provides the primary food source for the larvae of these flies. As the peat or coco coir breaks down, it attracts scavengers that thrive on the nutrient-rich decay.
