Why does your Gerbera Royal F1 Deep Pink 8016 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 substrate used for Gerbera Daisies. Their larvae live in the top layer of soil and feed on decaying organic matter and occasionally fine root hairs.
Gerbera Daisies are highly susceptible to root rot if the soil stays saturated. Constant moisture encourages fungal growth in the pot, which provides the primary food source and breeding ground for fungus gnat populations.
High levels of decomposing peat or compost in the Gerbera potting mix can attract flies. If the medium is too rich and stays wet, it creates a perfect ecosystem for larvae to develop.
