Why does your Lilium longiflorum Berg have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
This is the most common cause of fine webbing on Lilium longiflorum. The mites feed on the underside of lily leaves, injecting saliva that destroys plant cells and produces silk webs as they migrate.
While less common as a primary cause of webs, low humidity in lily greenhouses often triggers a population explosion of spider mites. The webbing is a physiological response to the lack of moisture in the microclimate surrounding the lily foliage.
While not producing silk, extreme fluctuations in water uptake can cause cells to burst, sometimes creating a fine, dusty or web-like appearance on the leaf surface due to mineral deposits and cell rupture.
