Overgrown Grapevine #625419

Asked April 19, 2020, 2:49 PM EDT

Hi! I'm hoping you can give me some advice on a severely overgrown grapevine I have in my home garden. By way of background, I believe I planted this grapevine 5 or 6 years ago. I had every intention of getting it trained on a trellis in year 2, but unfortunately life did not cooperate (I've been in and out of state over the past 4 years) and haven't had a chance to do anything with it. As you can imagine, it's become quite an overgrown mess. Also, at some point several years ago a well-meaning family member was trying to do some weeding while I was gone and chopped off the trunk maybe 6 to 8 inches above the ground, so it now stands less than a foot tall. From what I've read I believe a trunk is supposed to be 4-5 feet tall? I'm not sure how that may factor in, but I thought it was worth mentioning. I've also noticed that a lot of the old canes, since they are laying on the ground, have been putting down roots of their own. When I tried to lift them up to see if I could get some of the vine up off the ground, I quickly found that wouldn't be possible without pulling up the roots that have grown from the canes. I'm not sure where to go with it from here so I thought I'd send you folks an email and see if you could answer a few questions for me - any opinions or suggestions would be greatly appreciated! I'm also attaching some pictures that I hope will be helpful. The main trunk is visible near the upper right quadrant in all the pictures. Questions: 1) What would you recommend I do with my wildly out of control grapevine? 2) Would it be best to cut the trunk off an inch above ground level and start over? 3) Am I better off to try to dig up a couple of the canes that have put down roots and try to transplant them instead of trying to resurrect the original main trunk? 4) And a big question - Is it too late to do anything with it this year? I know it's supposed to be dormant for pruning so am wondering if I can even cut it back this year given that it’s mid-April already. I'm open to trying pretty much anything at this point, and if it's not salvageable I totally understand that! Thank you so much for your time and I look forward to hearing from you!
