Why does your Sinningia speciosa Empress Red have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The presence of tiny black flies in Sinningia speciosa is almost certainly due to fungus gnats, which lay eggs in moist organic matter. Their larvae feed on the delicate root hairs of the Gloxinia, potentially leading to root damage and reduced flowering.
Fungus gnat populations explode when the substrate stays consistently wet, a common issue for Sinningia species which are prone to rhizome rot. Excessive moisture provides the perfect breeding ground for fly larvae within the peat-heavy soil.
The use of overly rich, uncompacted compost or old potting mix can provide a nutrient-dense food source for fly larvae. In Sinningia, decomposing leaf litter or dead root fragments within the pot attract these pests.
