Two-Spotted Spider Mite Infestation

Spider mites thrive in the warm, dry conditions often experienced by Chrysanthemums. They pierce plant cells to feed on sap, leaving behind fine silken webs and causing stippling (tiny white/yellow dots) on the leaves.

Very Common

Tetranychus urticae (European Red Mite) Outbreak

Common in greenhouse-grown Chrysanthemums, these mites produce dense webbing as they colonize the undersides of foliage. This leads to rapid discoloration and eventual leaf drop if the population is not controlled.

Very Common

How to confirm: Inspect the undersides of the leaves for small, reddish or orange moving dots within the webbing.

High Humidity with Poor Air Circulation

While not a direct cause of webbing, excessive humidity combined with stagnant air can encourage certain micro-arthropods and make the plant more susceptible to mite silk production. It may also mask other fungal issues that accompany the stress.
