Why does your Lilium Corcovado 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 Lilium species. These arachnids pierce lily cells to feed on sap, leaving behind silken webs and stippled white spots.
In many lily cultivars, a specific strain of red spider mite creates dense webbing around the leaf junctions and flower buds to protect themselves from predators. This leads to rapid discoloration and potential bud drop in Corcovado lilies.
While not a direct cause of webs, extremely dry air can trigger a stress response in lilies, making them more susceptible to mite colonization and causing some fine, desiccated leaf fibers to look like webbing.
