Why does your Lilium Asiatic Hybrids 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 Asiatic Lilies. These arachnids pierce plant cells to suck out contents, leaving behind stippling patterns on the leaves.
A specific subspecies common in bulbous perennials, this mite creates dense silk webs to protect themselves and their eggs. In Asiatic Lilies, this often leads to premature leaf yellowing and desiccation of the flower buds.
While not a direct cause of webbing, extremely dry air can cause plant tissues to become brittle and trap dust or environmental debris that mimics fine silken textures. This is often accompanied by curling leaf margins in Asiatic Hybrids.
