Why does your Lilium oriental Laguna have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
The fine webbing is a classic sign of spider mites, which thrive in the warm, dry conditions often experienced by Oriental lilies. These arachnids pierce the lily's cell membranes to feed, causing stippling (tiny white dots) on the leaves.
A specific subset of spider mites that is highly aggressive on Lilium species during summer heat. They create dense silken webs to protect themselves from predators and environmental stress.
While less common for webbing, extreme humidity in dense lily beds can cause fungal hyphae to appear thread-like. This is usually accompanied by leaf discoloration rather than just silk.
