Pruning a big old grape
I bought a house with a big grape arbor that I love. Each of the past two years I've cut it back both in the winter and the summer because it grows so vigorously (you can't see that it crosses the fence and covers the side of the back porch). The structure of the arbor is rotted away and needs to be replaced. How far back can I cut the grape without killing it?

Thank you for your question. Grapevines are amazingly resilient, so you probably don't have to worry about pruning so much that you will kill this plant. And, if you're planning to replace the arbor, you'll need to remove most of it. Here is an Extension article on this topic, which has links to more information, including illustrations and photos: https://extension.oregonstate.edu/news/dont-be-timid-when-pruning-grapes I hope this is helpful. Good luck!
