Why does your Chrysanthemum Julio have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites are the most common cause of fine webbing on Chrysanthemums, especially in low-humidity environments. They feed on the undersides of leaves, injecting saliva that drains nutrients and creates silk webs to protect their colonies.
In warmer conditions, these mites thrive on Chrysanthemum Julio, causing stippling (tiny yellow spots) alongside the characteristic fine webbing. This leads to premature leaf senescence and reduced floral production.
While not a primary cause of webbing, excessive moisture trapped within dense Chrysanthemum foliage can create a sticky residue that traps dust and debris, which may be mistaken for fine silken webs. This is often accompanied by Botrytis risk.
