Why does your Lilium Oriental Robin Van Gaalen have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
These tiny arachnids thrive in the warm, dry conditions often found around Oriental Lilies. They pierce the plant cells to suck out sap, leaving behind characteristic fine silk webbing and stippling on the leaf surfaces.
While they don't create thick webs, broad mites cause leaf distortion and can contribute to a silken appearance due to secondary pest activity. They specifically attack the tender, developing tissues of the lily buds and young leaves.
Extreme dehydration in the microclimate around the Lily can cause leaves to curl and become brittle. In some cases, this physiological stress makes the plant more susceptible to secondary spider mite outbreaks which produce the webbing.
