Show How To Prune Grape Vines Do you have grape vines in your yard and are wondering how to prune them? There is no easy way to tell how to prune grape vines, says Melvin S. Bur-ningham, Bur-ningham, USU Area Hort-ticultunst. Hort-ticultunst. Generally, however, grapes should be pruned in late winter or in February. Most of the grapes in this area are pruned or (rained to the four arm of Kniffen svstem. This consists of a central trunk with two new canes (one on each side) running out from the main trunk at about 3 feet above ground and another set 4' feet high. These arms or canes are tied to wires that are stretched out about that distance from the ground. The canes are cut off annually an-nually so there are from ten to fifteen buds per arm. This will leave from 50 to 60 buds per trunk. All of the rest of the canes are cut back to the main trunk by leaving only a bud or two at each arm. These buds will grow out for next year's crop. Then next year ihe canes that bore this year will be cut back to buds close lo the trunk for the next year's crop. If you prune late in the spring manv of Ihe culs will bleed. This does not hurt the grape vines because it is mostly waier that is flowing through the vine. If you would like to have a good' publication on pruning your home orchard, come to our office, or your County Agent's Office for your copy or send 20 cents and the copy will be sent to you. Mr. Burn-ingham Burn-ingham concludes. |
