Set end posts at least 3 feet deep leaving 6 feet above ground. A typical trellis consists of firmly-set, well-braced posts at intervals of 10 to 15 feet along the row. It is important to choose your training system before you build the trellis.
#GRAPE TRELLIS PLUS#
The trellis must be strong and substantial enough to carry the weight of the vines plus a heavy crop during strong winds. Grapevines require support, which is most often provided by a trellis. Grapes trained to a VSP (vertical shoot positioning) system. Note that it is possible to grow vines using training systems other than those recommended, depending on your preference. The table below suggests training systems that are suitable for several cold-hardy grape varieties. We’ll discuss four systems that can work well and that are easy to implement in home vineyards in cold climates.

Similarly, shorter trunks are less likely to experience winterkill. In colder climates, cane-pruned systems are often better than cordon-pruned systems because they are less susceptible to winter injury. The training system chosen determines the type of trellis that you will need. Some of the basic differences between training systems relate to:ġ) whether fruiting shoots are borne on long canes that are replaced each year or whether they are produced from spurs on cordons that live for many years, 2) the height of the permanent trunks, which determines whether the fruiting zone is high (6-7 feet off the ground), low (3’ off the ground) or something in between, and 3) how the fruiting shoots are maintained throughout the growing season. Some training systems are better suited to certain cultivars, certain climates, and certain uses, than others. There are countless named pruning and training systems for grapes used throughout the world. Spur –a cane pruned to 1-3 budsTrunk –a permanent main stem that supports the fruit-bearingĬordon –semi-permanent branches off of the trunkTrellis –the physical structure used as support Shoot –the current season’s growth (has leaves, tendrils, and fruit clusters)Ĭane –a one-year old shoot(each bud on a cane produces a shoot) During the growing season, vines are trained to maintain a particular shape and to ensure that fruit are exposed to sunlight and airflow. Because healthy vines grow several feet per year and would naturally set far more fruit than they can ripen, they must be pruned each year when they are dormant to keep the vines producing fruit and to keep them from taking over an ever increasing space. Grapevines produce fruit on new growth each year. In this publication, we discuss the importance of pruning and training grapes, and describe some of the training systems that can be used successfully in home vineyards. A small home vineyard with even just a vine or two can be a beautiful and productive addition to the landscape, yard or patio.įor more complete information about choosing varieties and establishing a small home vineyard, see our publication Growing Grapes in New Hampshire. Home-grown grapes make excellent fresh eating, juices, jellies, raisins, and wine.
