Why does your Amaryllis Faro have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
These flies breed in the moist organic matter of the Amaryllis potting medium. Their larvae feed on decaying plant material and can occasionally damage the developing root system of the bulb.
Excessive moisture in the Amaryllis pot creates an ideal breeding ground for fungus gnats and can lead to bulb decay. As roots rot, they release nutrients that attract flies to the soil surface.
If there is fermenting organic matter or decaying bulb scales present in the top layer of the soil, fruit flies may be attracted to the Amaryllis pot to feed.
