Why do asters get aster wilt?

Asters are affected by aster wilt, primarily caused by the fungus Ceratobasidium spp. This pathogen infects the plant through wounds and can lead to vascular system blockage, resulting in wilting and eventual plant death. Environmental stressors, such as drought or poor soil conditions, can exacerbate the disease's impact. Proper cultural practices, including crop rotation and maintaining plant health, can help mitigate the risk of aster wilt.
