Why does your Viola cornuta Lilac Rose White Centre have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlySpider mites thrive in the warm, dry conditions often experienced by Violas. They pierce plant cells to feed on sap, leaving behind fine silk webbing and causing the white centers of the flowers or leaves to appear stippled or bleached.
As a specific strain of spider mite, these pests are highly common in ornamental violets during summer heat. The fine webbing is a defensive structure used to protect their eggs and create micro-climates for the colony.
While less common for 'webbing,' extremely high humidity in dense Viola clusters can cause fungal hyphae to spread across leaf surfaces, appearing as a fine, white, web-like fuzz. This is often mistaken for mite silk.
