Why does your Chrysanthemum Jefferson have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
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.
While more common in Cyclamens, these mites can affect Chrysanthemums by causing leaf distortion and fine webbing, particularly in humid greenhouse environments.
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.
