Why does your Kalanchoe fedtschenkoi Rosy Dawn have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely the adult stage of fungus gnats, which thrive in the moist topsoil of Kalanchoe pots. Their larvae feed on organic matter and can damage the delicate root systems of succulent species by consuming fine root hairs.
Kalanchoe fedtschenkoi is a succulent that requires well-draining media; frequent watering creates the damp environment necessary for fungus gnat larvae to survive. Overwatering also stresses the plant, making it more susceptible to soil-borne pests.
Soil mixes containing high amounts of peat moss or compost provide an ideal food source for the larvae of black flies. These organic components retain moisture too effectively for Kalanchoe, facilitating a pest lifecycle.
