Why does your Yellow Zantedeschia Aethiopica have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
These small black flies thrive in the moist, organic-rich soil preferred by Calla Lilies. The larvae live in the top layer of soil and feed on decaying organic matter or occasionally fine root hairs, which can stress the plant.
Calla Lilies require consistent moisture but are highly susceptible to root rot if the substrate remains waterlogged. This creates a perfect breeding ground for fungus gnats and other soil-dwelling insects.
Old, decaying leaves at the base of the Calla Lily spathe can attract various small flies looking for a place to lay eggs. As the rhizome or foliage ages, it provides a nutrient-rich environment for insect larvae.
