Two-Spotted Spider Mite Infestation

This is the most common cause of fine webbing on Chrysanthemums. These arachnids thrive in the warm, dry conditions often found in indoor or greenhouse environments, feeding on the plant's sap and leaving silk webs as they move.

Very Common

High Humidity with Poor Air Circulation

While not a direct producer of webbing, extreme humidity can cause fine, fungal mycelium to appear similar to spider mite silk. In Chrysanthemums, this often accompanies 'Botrytis' or gray mold risk if the foliage stays damp.

Common

How to confirm: Check if the 'webbing' feels fuzzy and organic rather than structured/silky, and look for dark spots on nearby petals.

1 Improve air circulation around the foliage by using a small fan or spacing plants further apart to prevent moisture from settling on leaves.

2 Apply a fungicide to treat potential fungal mycelium and prevent the spread of Botrytis or gray mold.
