My parents have in their back yard a very well established concord grape vine that produces a more grapes than we can use. In the past I have never take much interest in it as my mother alway picked what she could process and the rest I guess went to waste. I was amazed by how many grapes it produced. In fact to pick them I had to cut through 80% of the vines. This I did this year in October. Question: Was I wrong in pruning this early and is there any thing I should do before winter sets in? Ps. I do not think this vine has been pruned since my parent brought the home in 1989
Some growers will do a light early pruning, and a final pruning early in the new year, others will prune a bit long or leave more spurs than necessary on the vine until the extent of any frost damage becomes apparent, still others whack it all off in the spring. Many vines are thinned or mechanically hedged during the growing season. You won't have damaged your plant, and January/February will be fine for a final pruning. Ralph
