Why does your Gerbera jamesonii Royal Red 417 have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites thrive in the warm, dry conditions often found with Gerbera cultivation. They feed on the underside of leaves, injecting toxins that result in characteristic fine silk webbing across the foliage and flower buds.
This specific mite species is highly common in greenhouse-grown Gerberas. In addition to webbing, you will likely see fine stippling (tiny white dots) on the red petals and green leaves as they drain cell contents.
While not a direct cause of webbing, extremely low humidity can weaken the Gerbera's cuticle, making it easier for mites to establish webs and causing the plant to become more susceptible to secondary pests.
