Hello, I had a Marquis grapevine that got black rot I couldn't get rid of. So I thought I will just dig it up. I quickly realized that was next to impossible. So I cut the trunk down all the way to underneath soil and cut most of the roots I could find with pruning shears. Then applied some Captan fungicide on top of it. Then put soil back over it. Then threw some wildflower seed over it. This was a little over a month ago. I have seen no signs of new life there. So I was considering replacing it with a Thomcord. My question is... Will it grow back and if so about how long would that take? And if not how long should I wait to plant another vine?
