Why does your Lilium hybrid Mitsuyo 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 Mitsuyo lilies. These pests pierce the lily's leaf cells to suck out chlorophyll, leading to stippling and eventual leaf senescence.
This specific species is highly common in hybrid lilies and produces dense silk webs to protect themselves during reproduction. The presence of fine webbing usually indicates a high population density that has begun creating protective colonies.
While less common as a direct cause of webbing, extremely dry environments can trigger mite outbreaks and cause the lily's silk-producing pests to produce thicker, more visible webbing as they seek moisture.
