Why does your Mini Rose Rosa Terrazza Pure 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 breed in the moist organic matter of the rose's potting soil. Their larvae feed on fine feeder roots and organic debris, potentially causing stress to the miniature rose.
Miniature roses like 'Terrazza Pure' are sensitive to damp, stagnant soil which attracts fungus gnats. Constant moisture creates the perfect breeding ground for larvae in the top layer of the substrate.
The use of heavy peat moss or uncomposted organic matter in the rose's potting mix provides a rich food source for fly larvae. This nutrient-rich but poorly aerated environment encourages insect populations to thrive.
