Why does your Mini Rose Rosa Terrazza Fragrance 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 breed in the moist organic matter of the potting soil. Their larvae feed on decaying plant material and can damage the delicate root systems of miniature roses.
Miniature roses are highly susceptible to root rot if kept too wet. Constant moisture creates the ideal breeding ground for fungus gnat larvae and promotes fungal pathogens in the soil.
A potting mix that is too rich in peat moss or compost can provide an abundant food source for flying pests. This excess nutrients and moisture retention attract gnats to the 'Rosa Terrazza' container.
