Why does your Lilium orientale have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites thrive in the warm, dry conditions often experienced by Oriental Lilies. They feed on the undersides of leaves, injecting toxins that cause stippling and create fine silk webbing as they build colonies.
A specific strain of mite common in ornamental Lilium species that can cause rapid defoliation. The webbing becomes denser as the population grows, often covering the leaf junctions.
While thrips primarily cause silvery scarring, heavy infestations in humid environments can sometimes lead to secondary silk-like strands from disturbed leaf surfaces or associated predatory mites.
