Why does your Portulacaria afra variegata 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 organic matter found in succulent soil. Their larvae feed on fungal mycelium and can damage the fine root hairs of Portulacaria afra, leading to reduced vigor.
Frequent watering or non-draining soil creates a perfect breeding ground for fungus gnat larvae. For this succulent, excessive moisture leads to a damp substrate that stays wet too long, inviting pests and potential root rot.
If there is old, decomposing potting mix or fallen leaves at the base of your Dwarf Jade, it provides a nutrient-rich habitat for fly larvae. These pests are attracted to the breakdown of organic material in the substrate.
