Why does your Chrysanthemum Castilho White have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites thrive in the warm, dry conditions often experienced by Chrysanthemums. They pierce plant cells to feed on sap, leaving behind fine silk webbing as they create colonies across the leaf undersides.
This specific mite species is highly aggressive on Chrysanthemum varieties. The fine webbing often becomes denser around new growth and flower buds, eventually causing leaves to turn chlorotic or bronze.
While not a direct cause of webbing, very low humidity stresses Chrysanthemums and creates an environment where mite populations explode. The plant's physiological stress makes it more susceptible to silk production by arachnids.
