Grape Vine Removal and Replanting
I have 10 Chambourcin vines about 8 years old that I want to remove and replant with another variety. What is the best way to remove them? They are woody, about 1-1.5 inches in diameter. They are vigorous but do not have the time to follow the proper spray regimen. As a result in all but 2 years black rot has claimed the crop before harvest. I would like to replant with U of MN winter hardy table and seedlees grapes. Should I just cut them a few inches above the ground then use a stump killer? If so, is it too late now that they are dropping leaves and going dormant? If chemical is the way to go and it should be a spring application painted on the stump, can I replant next to it? I am sure root system removal is not possible and even with chemical treatment they may continue to sprout for a while. Is there another way?
