Why does your Chrysanthemum Gerson have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
The fine webbing is a classic sign of spider mites, which thrive in the warm, dry conditions often experienced by Chrysanthemums. These arachnids pierce plant cells to feed on sap, leading to stippling and eventual webbing across the foliage.
While less common than spider mites, cyclamen mites can cause structural webbing and leaf distortion in Chrysanthemums. They tend to cluster around the tight buds and new growth of the Mum.
While humidity does not create silk, extremely dry air can cause the plant's cuticle to crack and make the existing silk from minor pest populations much more visible and structurally prominent.
