Why does your Cherry Tomato Pepe F1 have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely fungus gnats, whose larvae thrive in the moist organic matter of tomato potting soil. They feed on decaying plant material and can damage the delicate root systems of Cherry Tomato Pepe F1 by consuming fine root hairs.
Excessive moisture in the soil creates the perfect breeding ground for fungus gnat larvae. For Cherry Tomato Pepe F1, which prefers well-draining medium, constant wetness promotes both fly populations and potential root rot.
If there is a thick layer of decomposing compost or unfermented organic mulch around the base of the Pepe F1 plant, it provides an ideal food source and egg-laying site for flies.
