Why does your Mini Rose Steppe Ovation have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely adult fungus gnats, whose larvae feed on organic matter and fine root hairs in moist soil. In miniature roses like 'Steppe Ovation', high infestation can lead to root damage and stunted growth.
Fungus gnat populations explode when the growing medium remains consistently damp. For miniature roses, which require well-draining soil, prolonged wetness creates the perfect breeding ground for these flies.
Potting mixes containing high amounts of peat moss or decomposing compost provide an ideal food source for gnat larvae. The nutrient-rich environment needed for rose blooms can inadvertently attract these pests.
