Why does your Mini Rose Hippie Star 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 lay eggs in the moist upper layers of soil. Their larvae feed on organic matter and can damage the delicate root systems of mini roses.
Miniature rose varieties are highly susceptible to root rot if the substrate remains saturated. Persistent wetness provides the ideal breeding ground for fungus gnat larvae and promotes fungal pathogens.
If the potting mix contains high amounts of decomposing peat or compost, it creates a nutrient-rich environment for flies to breed. This decay attracts moisture-loving insects specifically to the rose's rhizosphere.
