Why does your Lilium oriental Viviana have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites are the most common cause of fine webbing on Oriental Lilies, especially in warm, dry conditions. These microscopic arachnids pierce plant cells to feed, leaving behind silk webs and causing stippling (tiny white dots) on the leaves.
In many regions, this specific subspecies of mite thrives on large-leaved lilies like 'Viviana'. They create dense webbing around the flower buds and leaf axils as the colony grows.
While not a direct cause of webbing, very low humidity can stress Oriental Lilies and make them more susceptible to mite outbreaks. Severe dehydration can sometimes cause leaf tissues to degrade in a way that traps environmental dust or fungal spores in silk-like patterns.
