Why does your Gerbera jamesonii Golden Yellow 54 have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyThe presence of tiny black flies around the base of a Gerbera is most commonly due to fungus gnats, whose larvae live in organic matter and feed on decaying roots. They thrive in the consistently moist soil conditions that Gerberas often experience during frequent watering.
While not the flies themselves, excessive moisture in the Gerbera's substrate creates the perfect breeding ground for fungus gnats. High humidity and waterlogged soil also trigger root decay, which attracts more scavengers to the plant.
While less common for flies, certain fungal pathogens like Septoria can cause lesions that decay plant tissue; if the plant is decaying, it attracts secondary pests including gnats.
