Pruning Concord Grape Vines
I've read were we should prune grape vines 75 to 90%
and only new kanes (vines) have grapes. My question is do the new kanes (vines) only have grapes on the 2nd year ? My one old grape vine, I prune to a 6 ft. stump you might say last winter. This year it grew more vines than I new what to do with. It had about 20 clusters. Not many grapes. I planted 5 more last April 2013. I have many long vines, maybe 16 feet long. Should I leave these vines to have grapes next year ?
In other words do new vines only have grapes, when does this happen ? The first year or the 2nd year.
