Pruning concord grape — FAQ
When should I prune concord grape?
Late winter or early spring while fully dormant, after the coldest weather has passed. Using the four-cane Kniffin system, select four vigorous one-year-old canes (pencil-thick, well-spaced) and tie them to the trellis wires. Cut all remaining canes back to 2-bud renewal spurs. Each retained cane should carry 8–12 buds.
How often does concord grape need pruning?
Annually. Yes — Concord grape requires hard annual pruning; unpruned vines produce excessive foliage and poor fruit. Concord is typically trained on a two-wire trellis using the Kniffin system. Each winter, retain only two or four canes from the previous season and prune everything else away — grapevines fruit only on one-year-old wood.
