Verticillium Wilt. Most species of maple are susceptible to Verticillium wilt, and vine maple is no exception. The disease, caused by fungal pathogens, causes foliage to yellow and brown before it shrivels up and drops prematurely from the tree. The disease eventually becomes evident on entire sides of the tree.
Small amounts of these colors have been in the leaves all along. We just can't see them in the summer, because they are covered up by the green chlorophyll. The bright reds and purples we see in leaves are made mostly in the fall. In some trees, like maples, glucose is trapped in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn cause the leaves turn this glucose into a red color. The brown color of trees like oaks is made from wastes left in the leaves. It is the combination of all these things that make the beautiful colors we enjoy in the fall.
