Re: redbud

The soil-borne fungus, Verti-cillium albo-atrum, causes Verti-cillium wilt. Infection occursthrough the root system. Thefungus is an excellent soil inhabit-ant, and produces resting struc-tures that can survive in soil formany years. The fungi that growfrom these structures can directlypenetrate roots of susceptible hostplants. Growth within the hostoccurs within the water-conduct-ing tissues, resulting in blockageof water movement from the rootsto the foliagThe soil-borne fungus, Verti-cillium albo-atrum, causes Verti-cillium wilt.

I'm not really sure that's what caused it. I've read up on it and the tree did not show any indication previously. And this tree was 15 years old.
