Why does your Lilium Esta Bonita have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
These microscopic arachnids thrive in the warm, dry conditions often experienced by Lilium cultivars. They pierce the lily leaves to feed on cell contents, leaving behind fine silk webbing as they migrate across the foliage.
While less known for large webs, broad mite infestations can cause stunting and distorted growth that may be accompanied by fine silken strands in tight leaf axils. They are particularly destructive to the tender new growth of Lilium bulbs.
Though thrips are primarily known for silvery scarring and stippling on Lilium petals and leaves, their movement through dense foliage can sometimes drag fine silk threads or debris, mimicking a webbed appearance.
