Why does your Lilium oriental Sheila have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites thrive in the warm, dry conditions often experienced by Oriental lilies. They pierce cell walls to feed on the sap, leaving behind fine silk webbing and causing stippling on the foliage.
While they do not produce visible webs, heavy infestations can cause leaf distortion and secondary webbing-like textures due to plant stress. They are particularly destructive to the tender new growth of lilies.
The presence of webbing without visible pests can sometimes indicate an ecosystem imbalance where predatory mites have failed to control a minor spider mite population.
