Why does your Lilium oriental Salmon Star have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites thrive in the warm, dry conditions often found around oriental lilies, using fine mouthparts to pierce plant cells. The 'fine webbing' is a characteristic protective silk structure built by the mite colonies as they multiply on the foliage.
While broad mites are too small to see, they cause stunting and distortion that can sometimes be accompanied by microscopic silkiness or secondary webbing from other pests. They primarily attack the emerging buds of Oriental lilies, causing them to deform.
These mites can cause localized stippling and light webbing on the undersides of lily leaves. They tend to prefer the more sheltered, humid microclimates found within the dense foliage of large-flowered lilies like Salmon Star.
