Why does your Lilium Oriental Melanie have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
These microscopic arachnids pierce the cell walls of the lily leaves to feed on sap, leaving behind characteristic fine silk webbing as a refuge. This is particularly common in Lilium species during hot, dry periods when humidity levels drop.
A common pest for hybrid lilies, these mites create much finer, less noticeable webbing that often appears first on the undersides of the foliage. They thrive in the microclimate created by dense lily foliage during summer heat.
While not a web itself, the rupture of cells due to uneven water uptake in lilies can create a textured, crusty surface that may be mistaken for webbing or debris. This occurs when root pressure exceeds the plant's ability to transpire moisture through stomata.
