Why does your Chrysanthemum Givanildo have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
This is the most common cause of fine webbing on Chrysanthemums, especially in warm, dry conditions. These arachnids feed on the undersides of leaves, piercing cells and leaving behind silk webs as they move and reproduce.
As spider mite populations grow on Chrysanthemums, the webbing becomes denser and more structural, often covering entire leaf clusters or flower buds. This inhibits photosynthesis and can lead to premature leaf drop.
While not a direct cause of webbing, extreme fluctuations in moisture can cause cells to burst, creating a sticky residue that traps dust and environmental debris, which may look like fine filaments. This often occurs when Chrysanthemums are overwatered in high humidity.
