Why does your Pelargonium Black Velvet F1 Salmon 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 consistently moist organic matter used for Pelargonium. Their larvae feed on organic matter and can damage the delicate root system of your 'Black Velvet' cultivar.
High moisture levels in the potting medium create the perfect breeding ground for gnats. For a Zonal Geranium like 'Black Velvet', keeping the top inch of soil too wet prevents necessary drying cycles and attracts pests.
If the potting soil contains high amounts of uncomposted peat or bark, it provides an abundant food source for larvae. The breakdown of this matter releases CO2 and moisture that attracts flies to the plant.
