Why does your Kalanchoe blossfeldiana have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are most likely fungus gnats, whose larvae thrive in the moist organic matter of Kalanchoe potting soil. They feed on decaying plant material and can damage the delicate root system of your Kalanchoe if left unchecked.
Kalanchoe are succulents that require well-draining soil; constant moisture creates a breeding ground for fungus gnat larvae. High humidity and wet topsoil encourage the life cycle of these flies.
Decaying leaves or excessive compost in the Kalanchoe pot provide a nutrient-rich environment for fly larvae. As succulent leaves drop and rot on the soil surface, they attract more pests.
