Why does your Gerbera Royal F1 Deep Orange 292 have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely the adult stage of fungus gnats, which thrive in the moist organic matter found in Gerbera potting mixes. Their larvae feed on decaying organic material and can damage the fine feeder roots of the Gerbera daisy.
Gerberas are highly susceptible to crown rot and root issues if kept too wet. Constant moisture in the substrate creates an ideal breeding ground for fungus gnat larvae and promotes fungal pathogens.
While typically a fungal disease affecting leaves, high humidity and moisture that attract flies can also trigger black scabby lesions on Gerbera foliage. The presence of flies often coincides with the decaying organic matter produced by such fungal infections.
