Oh boy, I must be a genius.
Years ago I taught a MG class on pruning grape vines and demonstrated it on a cold winter day. This would spur new growth on the vines come spring. Pruning them in the summer when their sap was high would result in them bleeding to death. Guess when I decided to clear out some wild grape vines on our property. Winter! I did it then because there were fewer bugs and brush to wade through. DUH, they were so rampant the following summer I could have started a winery. Oh yeah, then I remembered when it was really supposed to be done. Genius.
