Why does your Chrysanthemum Oliveira 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, particularly in dry, warm conditions. They feed on the underside of leaves, sucking out chlorophyll and leaving behind tiny yellow speckles and characteristic silk webs.
This specific species thrives in indoor or greenhouse Chrysanthemum environments with low humidity. As the population grows, the webbing becomes more dense and covers entire leaf clusters, eventually causing bronzing of the foliage.
While humidity doesn't create silk, very dry air stresses Chrysanthemums and creates an environment that accelerates mite reproduction and makes the plant more susceptible to web-spinning pests.
