Why does your Gerbera jamesonii have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The most common cause for tiny black flies around Gerbera daisies is fungus gnats, whose larvae thrive in the moist organic matter of the potting soil. They are attracted to the high humidity and frequent watering often required by Gerbera species.
While Botrytis is a fungus, the presence of decaying flower heads or stem tissue on a Gerbera can attract various small flies for feeding. The moisture held in the crown of the Gerbera makes it a prime breeding ground.
If the Gerbera is kept in a highly fertilized environment with fermenting organic matter in the soil, fruit flies may be attracted to the decaying nutrients. This is less common than fungus gnats but occurs in over-fertilized potting mixes.
