Why does your Amaryllis Magic Green have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely fungus gnat adults, which lay eggs in organic-rich, moist soil. Their larvae feed on the decaying organic matter and fine root hairs of your Amaryllis, potentially causing root damage.
Fungus gnat populations explode when Amaryllis soil remains consistently wet, which also risks bulb rot. High humidity and frequent watering create the perfect breeding ground for these pests.
Overly compost-rich or old potting soil provides a nutrient source for gnat larvae. As organic components break down, they attract scavengers that appear as small black flies.
