Growing grapevines has been a part of people's lives for thousands of years.
Although there are several ways to care for and grow grapevines, it is necessary to prune all grapevines each year. Pruning a grapevine produces healthy, abundant grapes.
Prune grapevines in late winter to early spring. This is the best time because the vine is dormant.
Understand how your grapevine grows in order to figure out how to prune it. The two main growing methods are called the six-cane Kniffin system and the four-cane Kniffin system. In the four-cane method, there are two canes/branches, with two on each side of the main stalk of the grapevine. The four branches are supported on a trellis by two wires. The six-cane system is similar, but there are six branches on three wires.
Use the pruning shears to prune the canes according to how many branches you are supposed to keep. For the four-cane system, prune down to four canes; in the six-cane system, prune down to six canes.
Make sure you keep enough buds on the canes. On average, you should keep about 30 buds per pound of pruned material, and for each additional pound, add 10 more buds.
Keep a close eye on the growth of the grapevines to keep them healthy and strong. Make sure the canes are tied securely to the wires.
