Out of Control Grape Vines!

A:

It is best to prune back the vine to the form that you want. Since it has not been pruned for years, it will require you to prune back to older wood, and you will not have fruit this coming year. Keep in mind that only 1-year old wood (shoots that grew last year) will contain fruitful buds. It would be best to prune back your vine to the trunk with a few spurs (if possible) to grow during this summer. Try to form the vine to your desired shape (on a trellis, hopefully) during the summer, and remove extra shoots. Next winter, you should plan to prune back your vines and maintain buds on those 1-year old shoots for next year's fruiting. See more details on pruning grapevines and video resources (http://www.extension.org/pages/31140/pruning-grape-vines:-an-overview).

If you have future questions regarding your vines, please contact your local county Extension office and Master Gardener program for support. Also, please see our Extension catalog (https://catalog.extension.oregonstate.edu/) for helpful document sand guides from OSU Extension Service.
