Two-Spotted Spider Mite Infestation

The presence of fine, silky webbing on Chrysanthemums is a classic sign of spider mites feeding on the undersides of leaves. These arachnids pierce plant cells to suck out nutrients, leading to stippling and eventual leaf drop.

Very Common

Tetranychus urticae (European Red Mite) Outbreak

In warmer, drier conditions, Chrysanthemums are highly susceptible to red mites which create dense webbing to protect their colonies. This specific pest thrives in the microclimate created by the dense foliage of 'Tinga' cultivars.

Very Common

3 Increase local humidity and avoid dry, hot conditions by misting the foliage regularly to make the environment less hospitable for mites.

warning

Extreme Low Humidity

While not a direct cause of webbing, very low humidity stresses Chrysanthemums and accelerates the life cycle of mites. This environmental stress makes the plant more vulnerable to visible silk production by pests.

Common

How to confirm: Check if your indoor environment or greenhouse has fallen below 40% relative humidity.
