Why does your Lilium oriental Caurengo 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 underside of the leaves, injecting saliva that damages plant cells and produces fine silken webs as they move across the foliage.
Similar to the Two-Spotted variety, these mites create delicate webbing on Lilium species. They are particularly destructive to larger-leafed Oriental cultivars like 'Caurengo' when humidity levels drop significantly.
While not a primary cause of webbing, extreme moisture trapped within dense lily foliage can lead to secondary pest colonization or structural breakdown that mimics web-like patterns through decay.
