Today I’m gonna attempt to explain grape pruning. I found grape pruning very confusing at first. But not to worry-you will start to understand as you do it. Also look at the many videos on youtube on this subject. If you haven’t pruned your grape plants yet, now is a good time to do it. The best time to prune grape vines is in late winter and early spring, when the leaf buds on the tips of last year’s canes start to swell. There are 2 styles of pruning-cordon pruning and cane pruning. If your not sure what kind of grapes you have, then try cane pruning.
Cane pruning-This is how I prune my table eating grapes. My variety is Himrod, a green seedless table eating grape that does well here in Santa Fe. I have trained my grapes to grow on a fence but you can make supports as seen in the video below if you want.
I started with 2 main vines (called cordons) from the main plant years ago. They’re basically in a T shape off the main. A few years later I let 2 more canes grow on a lower level. Kinda a modified cane pruning because I let more than 2 grow off the main plant–2 cordons on the top and 2 lower. Off these cordons, each year new smaller cane vines will grow vertically from which the grapes come. I will trim back (but not off) these vertical canes before the growing season. I cut the old 1 year growth from last year canes (which are lighter brown than older growth) back to 3 buds on each cane to grow again. Each bud will put out new canes and off these new canes will grow grapes. I try to have at least 6″ to 12″ of space between the canes along the 4 main cordons so as not to overcrowd. Sometimes a cane will grow 4-10′ or more in length. I cut these back the same way. You may think you are cutting off too much, but grape plants are very forgiving and I rather not have a grape plant that is out of control with too many canes growing every which way. Besides your grapes will be bigger.
Look at this video that I found online. I Hope it helps visualize this process:
