Why does your Viola Cornuta True Blue have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlySpider mites are the most common cause of fine webbing on violets, especially in dry conditions. They pierce the cell walls of the Viola cornuta leaves to feed, causing stippling and silk production to protect their colonies.
In warmer climates, this specific mite species thrives on Viola species, creating dense webs that can eventually lead to leaf chlorosis and premature dropping of the blue flowers.
While rare, extremely high humidity combined with poor airflow can sometimes cause certain fungal structures to appear as fine, thread-like networks on the foliage of violets.
