Where did you get the vines? Are they self rooted or grafted? When you say buds, do you mean flower clusters (look like tiny grape clusters)? Even though I picked off the flower clusters about four of my first year Foch hid tiny grape clusters down in the grow tubes. Marechal Foch is a hardy variety but early bud break may mean that the clusters are killed by frost, though they should have a small secondary crop. How are you pruning the vines and maybe most importantly, when are you pruning? If you are pruning too early that will encourage earlier bud break and cluster freeze.Thanks.. the issue is there are No Buds at all in last 3 years!!...help !
