However, in lower elevation locations where heat and light It is usually done one to two weeks after bloom, before tendrils have become firmly attached. Planting grape vines (Vitis vinifera) from existing shoot cuttings saves money and is fairly straightforward. 4-Wire Vertical Shoot Position System (VSP): Combing or shoot positioning can help to reduce the overall number of tangled shoots and can increase light penetration into the vine canopy. Once green shoots are developed enough (approximately mid-July), each shoot can be placed in an orderly position along the entire cordon of the vine and parallel to the vertical trunk. 30 in.

A vine is contained within its vine space through a combination of vine management practices including choice of training system, pruning, shoot positioning and fertil- ization. Vertical Shoot Positioning: is a training system used with single or double Guyot, cane-pruned training, or with a Cordon, spur-pruned system. Proper shoot positioning results in orienting shoots to create a uniform distribution of foliage that minimizes shading of fruit. Manual shoot-positioning was performed at least twice each season to maintain two discrete canopies per vine. VSP is very common in cool and/or humid climate regions with low to moderate vigorous growth, as it encourages better air flow through the vine. 12 in. The video shows how training wires are used for vertical shoot positioning. They want to run free in all directions. The catch wires support the vines so they don’t flop on the ground. Submitted by: Michigan Grape Society P.O. Shoot positioning involves pairs of movable wires, with the paired wires installed on opposite sides of the vine row. Those plants have plenty of room to breath and lots of leaf surface area to soak up the sun. This trellis system is low cost and easily maintained. GDC is a horizontally divided canopy with shoots oriented down-ward from cordons spaced 1.2 m apart. Tucking of shoots will need to be done several times during the growing season. An open canopy is essential to the productivity of the vine as well as fruit quality. 12 in. Growing grapes has been a long tradition in many home gardens. Timing of positioning the shoots downward for Smart-Dyson and Scott-Henry usually occurs within a short window for individual varieties – before the shoots may break off – after the shoots … Vertical Shoot Position, or VSP, is a common and widely used trellis system. The apparatus is a linear grid composed of transverse and longitudinal elements that are configured to result in a network of spaces that are sized to substantially provide a separate space for each vine shoot. It is a horizontally divided trellis positioning the shoots in an upward direction of 10 to 15 degrees from vertical angling outward. With thousands of vines on the farm, we’ll be busy with this for a while. Vine training systems can be broadly classified by a number of different measurements. The vertical shoot positioning system (VSP) is a vertical divided trellis system that maximizes the capturing of sunlight for high yields. All three training systems used bilateral, cordon-training, and spur-pruning, In most training systems, shoots can be positioned manually or mechanically with specialized equipment. A VSP trellis system can consist of four to six levels of wire. TWC, GDC, and VSP are commonly used acronyms in the grape growing industry. Year 1 12 in. We position grape shoots in catch wires to guide them towards the sky. Required fields are marked *. We gently guide the growing vines between the wires. Shoot positioning Shoot topping The Grapevine is a true vine that requires some form of support to keep it off the ground. This work is supported by New Technologies for Agriculture Extension grant no. Box 151 Baroda, Michigan 49101. In a cane pruned, VSP trained site, shoot positioning serves as the next step after green pruning.While green pruning forms the basic architecture of the vine, shoot positioning manicures and directs the growth of the vine. However, positioning at 4 or 6 weeks after bloom was associated with a significant reduction in yield. This trellis system is know as the Vertical Shoot Positioning system: Here is an example of an in-line wire tightener. getting ready to shoot position: (from left) Bryce Potter, me, Paul Sloan, May 2015. As in other divided systems vines can be alternate to opposite sides, or occupy both sides of the trellis. Sunlight encourages the development of more fruitful buds for next year’s crop. In a low cordon trellis system, such as Vertical Shoot Positioning or VSP, the process is sometimes referred to as “tucking,” since canes are tucked upward between a set of catch wires as they develop. 30 in.

Some people call the process “combing” because once the vine crawl up the wires, they are straight and spaced out like the teeth on a comb. Row orientation perpendicular to seasonal wind direction may also cause difficulties with maintaining canopy division. Proper shoot positioning results in orienting shoots to create a uniform distribution of foliage that minimizes shading of fruit. In the VSP system, the vine shoots are trained upward in a vertical, narrow curtain with the fruiting zone below. The work we did today, will support the vines for a little while. 12 in. The vertical shoot position (VSP) trellis system is suited for grapevines with upright growth habits. Never Miss a Post. how mulch helps our sustainable farming efforts. Year 3 12 in. proper training, balanced pruning, and application of shoot positioning and/or summer pruning techniques can all serve to minimize shading. By this time next week, they will have grown enough to guide them into the second row of wire. Shoot positioning is per- formed in all vineyards trellised to the lyre, verti- cal-shoot-positioned, Scott Henry, Smart-Henry, and … On high cordon systems such as Geneva Double Curtain or GDC, and bi-lateral cordon, shoots are positioned so they grow downward and out from the cordon. Disease pressure is lessened due to increased air flow and sunlight penetration. Training Systems for Grape Vines Systems for Vines with a Trailing (procumbent) Growth Habit Head (long cane) Training Systems: 4 and 6-cane Kniffen: ... – Uses shoot positioning to expose fruit for ripening. The bottom wire known as the fruiting wire is set approximately 30" off the ground. Not only is shoot positioning important for the current growing season, it also has an impact on productivity in the following year.
