What causes redbud leaves to turn brown?
Verticillium fungi attack the Eastern redbud's vascular system, resulting in severe damage to the foliage, shoots and branches. Leaves fade and may turn brown and wilted in scattered patches of foliage. As the infection spreads, shoots and branches die, usually on only one side of the tree, a phenomenon that aids in diagnosing the disease.
How to treat redbuds from cankers?
Cankers can grow large enough to girdle branches and limbs, and if left unchecked, can kill the tree. Redbuds suffering from cankers should be treated as for verticillium wilt. When pruning, cut beyond the canker into healthy wood to ensure that all the infection in that area is cut away. Keep the tree healthy, but avoid over-fertilizing, which can strengthen the infection and cause it to spread.
Why do my trees have rot?
Rots of the roots and base of the tree are generally caused by the Phytophthora species of fungi. The leaves change color, may become stunted or crinkled and fall prematurely. Cankers or dark streaks may appear on the trunk, and sap may leach from the streaks or stains. Areas of foliage may die and eventually, the entire tree can die.
How do redbud trees survive?
Borers, for instance, generally target trees stressed by drought or other environmental condition. Borers penetrate the trunk, leaving small holes. The insects chew through the soft, inner tissue of the tree and damage its circulatory system, interfering with its ability to spread nutrients and moisture to the leaves. Once inside the tree, pesticides can't reach boring insects to kill them. The best defense is to maintain proper cultural care to make the tree less attractive to insects.
What is the color of redbud?
Best in U.S. Department of Agriculture plant hardiness zones 5 through 9, Eastern redbud's blooms may be white, pink, lavender or red, depending on the cultivar. The abundant flowers emerge before the leaves, decorating the bare branches with bright color, often until early summer. In the fall, the tree's heart-shaped leaves put on their own show, changing from green to dazzling gold. The tree is susceptible to verticillium wilt and may fall prey to other diseases and damaging insects.

I would also be reluctant to assess that as verticillium, although it could be early symptoms of a root rot. And if you suspect or know a plant has VW, the last thing you want to do is move it.......all that will do is spread the pathogen to other areas of your garden. And since it is nearly always fatal and a huge range of plants are susceptible, that is definitely NOT something you want to do!!
