Why does your Lilium Melesco 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 toxins that cause stippling and the production of fine silk webbing as they build protective colonies.
A specific subspecies of spider mite that is highly aggressive on Lilium species. The webbing becomes denser as the population grows, often resulting in the leaves turning yellow and eventually bronze or desiccated.
While not a direct cause of webbing, prolonged periods of very low humidity can cause the fine hairs (trichomes) on certain lily varieties to catch dust and debris, mimicking a web-like appearance.
