Why does your Chrysanthemum Pico Casa 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 found around Chrysanthemum plants. These pests pierce plant cells to suck out sap, causing stippling (tiny yellow dots) on the leaves.
In many indoor environments, this specific species of mite creates dense webbing around new buds and leaf axils on Chrysanthemums. As the population grows, the webbing covers larger areas of the plant, eventually leading to leaf bronzing.
While webbing is usually insect-related, extremely high humidity combined with poor airflow can cause fungal hyphae to appear like fine white threads on the plant surface. However, this rarely presents as structured 'webs' around stems.
