Why does your Hippeastrum Olaf have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The larvae of these flies live in the top layer of organic matter and feed on decaying roots and fungi. In Amaryllis, they thrive in the consistently moist soil required for bulb development, often causing secondary root damage.
The presence of flies often indicates an abundance of decomposing organic matter in the potting mix. For 'Olaf', a high-nitrogen or peat-heavy medium can attract flies that seek out these nutrient-rich decaying zones.
While not the direct cause of the flies, excessive moisture creates the perfect breeding ground for fungus gnats. This environment also stresses the Amaryllis bulb, leading to mushy, decaying roots which further attract scavengers.
