When should I prune new grape plants?

Question:

I have a grape pruning question. I planted three new grape plants in late May. I have since learned that I should have pruned them down to 1-2 primary stalks after planting, but I didn’t do that. I am wondering if I should do this now or wait until their dormant period, Jan-Mar next year?

Indeed, once the spring window is passed, our recommendation is to wait until the grape plants are fully dormant again before further pruning takes place. But you haven’t done anything harmful by doing the pruning then versus now.

Happy gardening.
