Mimosa Wilt Common in E. Texas

Mimosa Wilt Common in E. Texas

Have you ever wondered why there are not very many old, venerable mimosa trees around? Mimosas are a knockout when in bloom, and make a very pretty scene in the landscape. Some folks don’t care for them, though, due to their prolific seeding, resulting in many progeny popping up in unwanted locations.

Mimosa is susceptible to a soil-borne disease called Mimosa wilt, caused by the fungus Fusarium oxysporum f. sp. perniciosum. This fungus resides in the soil, and basically causes problems after infecting a tree by plugging up the vascular system of tree. Symptoms include yellowing of the foliage, wilting, and death, usually occurring during early to mid summer.

There is no cure for this problem, which is why there are not more mimosa trees across the Southern landscape.
