Two-Spotted Spider Mite Infestation

The presence of fine webbing is a classic sign of spider mites, which thrive in the warm, dry conditions often found around Chrysanthemums. These pests pierce the plant cells to suck out sap, leading to stippling and eventual leaf drop.

Very Common

How to confirm: Hold a white piece of paper underneath a leaf and tap the leaf sharply to see if tiny moving dots fall onto the paper.

Tetranychus urticae (European Red Mite) outbreak

A specific strain of spider mite that is highly aggressive on Chrysanthemums, creating dense silk webs to protect themselves from predators. They cause the salmon-colored flowers and foliage to look dusty or bronzed.

Very Common

High Humidity/Lack of Airflow (Secondary Webbing)

While not a direct cause of webbing, stagnant air can lead to fungal growth that may trap debris or silk from minor mite populations. This often accompanies the physical stress of localized microclimates within dense chrysanthemum foliage.

Common

How to confirm: Check if the center of the plant feels significantly more damp and suffocating than the outer edges.

2 Increase air circulation around the dense foliage by using a small fan or spacing plants further apart to prevent stagnant microclimates.

3 Prune away any heavily webbed or decaying stems to remove potential pest reservoirs and improve airflow through the plant center.
