Two-Spotted Spider Mites (Tetranychus urticae)

These tiny arachnids thrive in the warm, dry conditions often experienced by Chrysanthemums, feeding on leaf cells and leaving characteristic fine silk webbing as they move and protect their eggs.

Very Common

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

1 Immediately spray the plant with an organic miticide to kill existing mites, larvae, and eggs.
2 Increase humidity around the plant and ensure the soil remains moist, as spider mites thrive in dry environments.
3 Wipe down leaves with a damp cloth to physically remove webbing and any remaining pests.

Cyclamen Mites

While more common in Cyclamens, these mites can affect Chrysanthemums by causing leaf distortion and fine webbing, particularly in humid greenhouse environments.

Common

How to confirm: Inspect the undersides of leaves for tiny, moving dots accompanied by distorted or puckered leaf growth.

1 Apply an organic miticide spray to the plant to eliminate the mites and their eggs.
2 Inspect the undersides of leaves for more webbing and use a soft cloth to wipe away any visible pests.
3 Reduce humidity levels and improve airflow around the plant to make the environment less hospitable for mites.

Edema (Physiological)

While not a direct cause of webbing, high humidity causing cell rupture in Chrysanthemums can create blisters that may trap dust or debris, sometimes mimicking the appearance of fine silk to the untrained eye.

Rare

How to confirm: Look for small, corky bumps on the leaf edges rather than actual silk strands between leaves.

1 Inspect the undersides of leaves closely to confirm if the webbing is actually spider mite silk or just debris trapped in cell ruptures.
2 Reduce humidity and improve air circulation around the plant to prevent further cell rupture and edema formation.
3 If actual pests are found, treat the plant with an organic insecticide to eliminate any spider mite infestation.
