Why does your Viola cornuta Yellow Blotch Red Wing have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyThis is the most frequent cause of fine webbing on violets, especially in warm, dry conditions. The mites feed on the underside of leaves, causing stippling and creating silk webs to protect their colonies.
While not producing silk, rapid fluctuations in moisture can cause cells to burst, sometimes appearing as distorted, textured patches that may be mistaken for web-covered areas. This occurs when the viola roots take up more water than the leaves can transpire.
These mites are slower-moving than spider mites and prefer slightly cooler environments. They produce webbing that can appear more localized around the leaf margins or stems of pansy/viola varieties.
