Two-Spotted Spider Mite Infestation

The presence of fine webbing on Chrysanthemums is a classic symptom of spider mites, which thrive in hot, dry conditions. These arachnids pierce plant cells to suck out sap, causing the characteristic fine silk webs between leaves and stems.

Extreme Low Humidity/Desiccation

While not a direct cause of webs, extremely dry air can cause plant tissues to become brittle and may make existing mite silk more visible. It often exacerbates the impact of any existing pest presence on delicate cultivars like 'Pico Violento'.

Common
