Why does your Chinese Cabbage Enduro F1 have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyThe adult flies are likely fungus gnats, whose larvae feed on organic matter in the soil and can damage the fine root hairs of Chinese Cabbage. High moisture levels in the growing medium attract these insects and promote the fungal growth they depend on.
Certain small flies are attracted to the fermenting sugars in decaying organic matter or damaged cabbage leaves. While they don't directly eat the cabbage, their presence indicates an environment with high humidity and decaying plant debris.
Similar to fungus gnats, Sciarid flies thrive in the moist, nitrogen-rich soils often used for brassica crops like Enduro F1. Their larvae can cause secondary damage by feeding on stressed root systems.
