Why does your Sinningia empress wine red have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely fungus gnat adults, which thrive in the moist, organic-rich soil required by Sinningia. Their larvae feed on decaying matter and fine root hairs, potentially damaging the tuber's ability to uptake nutrients.
Excessive moisture in the Gloxinia substrate creates the perfect breeding ground for fungus gnat larvae. This condition can also lead to soft, decaying rhizomes which attract more pests due to the increased organic decay.
If there is old, dead foliage or decomposing peat moss in the pot, it provides a primary food source and egg-laying site for flies. Sinningia plants often produce heavy foliage that can rot if not pruned, attracting scavengers.
