Why does your Fuchsia fulgens 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 preferred by Fuchsia fulgens. Their larvae live in the top layer of soil and feed on decaying organic matter and fine root hairs.
Fuchsia fulgens requires consistent moisture but is highly susceptible to root rot if the soil remains saturated. Constant wetness creates the perfect breeding ground for fungus gnat larvae and attracts adult flies.
If using a heavy peat-based potting mix, the decomposing organic material serves as an ideal food source and egg-laying site for flies. The high nitrogen levels in such mixes can also stimulate rapid insect population growth.
