Now I've got a serious issue with one of my 4 coral bark maples. It has been growing like crazy for the last 8 years or so, but suddenly a couple weeks back started turning its fall color ( yellow ) . It is beautiful, but it's way too early for fall color.
The most troubling factor is that one small branch got shriveled up leaves and appeared dead. Now other branches seem to be quickly headed in that direction. All leaves have turned fall color, so it may be that the whole tree will be dead soon. The other coral barks are within 50 feet and are perfectly normal.
In doing some quick research, it appears it may be a disease called verticillium wilt which has no cure, and will probably kill the tree. Has anyone run into this disease and have any suggestions ?
