Why does your Mini Rose Lady 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 moist organic matter. Their larvae live in the soil and feed on decaying organic material and fine feeder roots of the miniature rose.
Frequent watering or poor drainage in miniature rose pots creates the perfect humid environment for fungus gnat breeding. This also increases the risk of root rot, which weakens the plant's ability to support new blooms.
Potting mixes containing high amounts of peat moss or compost provide an abundant food source for the larvae of black flies. In small containers like those used for Lady Star, this nutrient-rich environment can lead to rapid pest population growth.
