Why does your Mini Rose Pink Ricco Amorina 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 'Ricco Amorina' 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 suffocation if the soil remains saturated, which attracts these flies.
If you have recently added fresh compost or peat-heavy potting mix to your miniature rose pot, the decomposing organic material serves as a primary food source for fly larvae.
