Pruning "interlaken" grapes
I have an established pair of "interlaken" grape vines which are very prolific, but grow out of control . I would like to know the best way to prune them.
Washington County Oregon
Here is an excellent publication from Oregon State regarding grape growing in OR. There is a section about pruning that you should find helpful: http://smallfarms.oregonstate.edu/sites/default/files/publications/growing_table_grapes_ec1639_may_2...
