Why does your Viola cornuta Orange Red Wing have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyThe fine webbing is a classic sign of spider mites, which thrive in the warm, dry conditions often experienced by Viola cornuta. These pests pierce individual plant cells to suck out nutrients, leading to stippling and eventual leaf drop.
In many greenhouse-grown Violas, this specific mite species creates dense silken webs around the foliage to protect themselves from predators. It specifically targets the tender undersides of the orange and red petals and leaves.
While less common, certain fungal pathogens or even very dense clusters of fine mold can appear as thread-like structures in extremely stagnant, humid air. However, this is usually accompanied by dark spots rather than moving webs.
