Why does your Hibiscus rosa sinensis Cheerleader Clear Pink have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The presence of tiny black flies in the soil of a 'Cheerleader' hibiscus is most often caused by fungus gnats, which lay eggs in moist organic matter. The larvae feed on fine feeder roots and decaying organic material within the potting medium.
Hibiscus 'Cheerleader' varieties require well-draining soil but consistent moisture; however, leaving the top layer of soil wet for extended periods creates a perfect breeding ground for flies. Overwatering also stresses the plant, making it more susceptible to root damage from larvae.
If you have applied a thick layer of bark or compost to the top of your hibiscus, these decomposing materials serve as an ideal food source for fly larvae. The 'Cheerleader' series thrives in rich soil, but too much unintegrated organic matter can attract pests.
