Why does your Lilium orientale Casa Blanca have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites thrive in the warm, dry conditions often preferred by Oriental lilies. They pierce the plant cells to feed on sap, leaving behind fine silken webbing as they build colonies on the undersides of leaves.
While broad mites are too small to see, they cause physiological changes in Casa Blanca lilies that can sometimes be accompanied by secondary webbing from other pests. They primarily cause leaf curling and stunting.
Similar to the two-spotted variety, these mites create dense webbing in high humidity or drought stress periods. In Casa Blanca lilies, this often manifests as fine webs between the flower buds and upper foliage.
