I Just Looked Into The Plant Clinic Crystal Ball: I See Root Rot In Our Future!

Last year, on the days that I worked at the Plant Clinic, I looked at many plant samples that had root rot, thanks to last year's wet spring.  I fear that this spring is even worse, especially in the southern part of Illinois.  What do I expect to see?
