Why does your Lilium Boardwalk 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 Lilium species. They pierce the lily leaf cells to suck out contents, leaving behind fine silken webs as they move across the foliage.
Certain eriophyid mite species can cause fine, almost invisible webbing or stippling on lily leaves. They are often more subtle than spider mites but thrive in similar microclimates.
While not true webbing, certain fungal hyphae can appear as fine, hair-like structures on lily foliage in extremely stagnant, humid environments.
