Q. Should I cut my grapes back now or wait until spring?
A. I don’t like to finish pruning my grapes until about March 1. This is because I don’t know what kind of damage they will sustain this winter because of the cold and wind. If I prune them back to very short spurs or canes now, I run the risk of losing my crop or a majority of it.
I usually prune grapes in two steps in our Las Vegas climate; the first step I remove most of this last year’s growth down to about 18 to 24 inches long. Then I wait for the majority of the winter to pass.

The second step occurs close to the first week of March. This is the time when I prune the remainder of last year’s growth down to about one or 2 inches long if I I am producing on spurs and about 12 to 15 inches long if I am producing on canes.

Do not cut your grapes back yet. Wait until the major cold weather has passed.
