Why does your Allium schoenoprasum 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 live in the upper layers of moist soil and feed on organic matter or decaying root tissue. In Allium species, high moisture levels required for chives often create the perfect breeding ground for these pests.
Excessive moisture in the chive pot or garden bed promotes fungal growth, which attracts fungus gnats. This environment can also lead to root rot in Alliums, further weakening the plant's structural integrity.
If you have recently added fresh compost or manure to your chive bed, the decomposing organic material serves as a primary food source and breeding site for small dipteran flies.
