Why does your Mini Rose Ocean Ovation have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely fungus gnat adults, which thrive in the moist, organic-rich soil typically used for miniature roses. Their larvae feed on decaying organic matter and can damage the delicate root systems of 'Ocean Ovation' by feeding on fine feeder roots.
Excessive moisture in the potting medium creates the perfect breeding ground for fungus gnat larvae. Miniature roses are highly susceptible to root rot if the soil remains saturated, which also attracts these flies.
A potting mix that is too rich in compost or peat moss provides an abundant food source for the larvae of small flies. While roses need nutrients, an imbalance can lead to a population explosion of pests.
