Why does your Chrysanthemum Coutinho have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites are the most common cause of fine webbing on Chrysanthemums, thriving in warm, dry conditions. They pierce plant cells to feed on sap, which leads to stippling and the production of silk webs for protection.
This specific mite species is highly aggressive on Chrysanthemums and creates dense webbing that can eventually cover entire flower heads. Their presence often leads to premature leaf drop and yellowing of the foliage.
While not a direct cause of webbing, very low humidity levels stress the Chrysanthemum and trigger spider mites to multiply rapidly. This environmental condition makes the plant more vulnerable to silk-producing pests.
