Two-Spotted Spider Mite Infestation

Spider mites thrive in the warm, dry conditions often found around Chrysanthemums. They pierce plant cells to feed on sap, leaving behind fine silk webbing as they build colonies on the undersides of leaves.

Very Common

Tetranychus urticae (European Red Mite) Outbreak

Often appearing as fine webbing on newer growth, these mites cause stippling (tiny yellow dots) on the Chrysanthemum foliage. This is particularly common when humidity levels drop significantly.

Very Common

High Humidity/Microclimate Mold (Secondary Symptom)

While webbing is usually arachnid-related, extremely dense, fine fungal mycelium can sometimes be mistaken for webbing in high-humidity Chrysanthemum environments. This occurs when air circulation around the bushy foliage is poor.

Common

How to confirm: Check if the 'webbing' is actually fuzzy and disappears when touched or if it feels structural and silk-like.

1 Improve air circulation around the dense foliage by using a small fan or spacing plants further apart to reduce the microclimate humidity.

2 Inspect the plant closely for tiny moving arachnids; if pests are found, treat the plant with an organic insecticide/miticide spray.
