Cordon-trained vines are pruned to spurs, and the same techniques are used as for head training-spur pruning. Diagrammatic drawing showing of pruning a head-trained spur-pruned vine (upper) and a head-trained cane-pruned vine (lower). Dark-shaded water sprouts, suckers, and portions of canes are removed at pruning.
Canes are either mature shoots after they have produced fruit and the leaves have dropped in the fall, or canes that are able to bear fruit; those are called fruiting canes. Cordons: used in grape training and pruning when referring to the “arms” of a grapevine that extend from the trunk.
This is a video made by donna hirschfelt for classes she teaches on establishing small vineyards in california.
Now we come to the spur-pruning (also known as cordon-trained) vines, in which the trunk of the vine is allowed to extend horizontally along a wire, yielding shoots over many years. Common in warm-climate growing regions, spur-pruned vines are easier to prune than many cane-pruning systems, especially guyot, due to the height of the vines.
To spur prune the vine, completely remove the cane that is the farthest away from the permanent cordon. The cane that is the closest, however, is pruned to 2 to 4 buds, depending on the fruitfulness of basal buds and the desired cropping level, which will grow into next year’s spurs.
Young vines are carefully trained to either one or two trunks. The fruiting area is established as either head-trained (figure 1b) with canes (hardened-off shoots), permanent cordons (horizontal arms) with dormant canes pruned back as spurs, or a fan-shaped arrangement on top of a four-post arbor structure.
Cane pruning is most popular in burgundian-styled vineyards (pinot noir, table grapes and other lower vigor, cool climate grape varietals). Say you are looking at a dormant vine that you want to “cane prune. Canes are sprouting all over the place, and the vine needs to be “tamed.
Systems for vines with a trailing (procumbent) growth habit head (long cane) training systems: 4 and 6-cane kniffen: • advantages: – ease of pruning to long canes. – more compatible with tolerating winter injury than cordon systems.
2) pruning has a depressing effect on the vine 3) capacity of the vine directly related to number of shoots retained 4) production of crop depresses vine capacity 5) shoot vigor is indirectly related to cluster number 6) bud fruitfulness is indirectly related to shoot vigor 7) old growth (a large cane, arm) can carry more.
The head system develops fruiting canes and renewal spurs near the trunk on very short branches (arms).
Vine training head training - this is when the vines don't have a lot of permanent wood.
Jun 27, 2019 it is best the first dormant season to cane prune the grapes as described above. Then when your plants start to put out blooms, look at where they.
Grapes need to be trained onto a trellis in order to spread the vine and provide light to the leaves and fruit clusters. There are two general systems for training vines and two different pruning methods. 1) in the “head-trained” system, a trunk is established and 4-6 short cordons are developed.
Cane pruning (guyot) is commonly used in cooler climate growing regions, including burgundy, sonoma, and oregon. By limiting the vine’s lignified growth (the hard brown part) to just the trunk, the vine is less vulnerable to frost and better protected than spur pruned vines.
Mature vines of head-trained, cane-pruned cabernet sauvignon in a trial located near oakville, california, were converted in 1979 to bilateral cordon training.
Dec 23, 2008 some research suggests that cordon-trained and spur-pruned vines might advantages of head-training and cane-pruning, on the other hand,.
While cordon training/spur pruning is by far the most popular training/pruning combination, many vineyard owners also employ head training/cane pruning, particularly in hybrid grapes trained to low trellis systems with vertical shoot positioning.
An increasingly popular way of growing both redcurrant and white currants is as the cordon system. This saves a great deal of space in the garden as a single cordons can be planted just 15” apart, with double cordons only 18”-24” apart. A single cordon will have just one main stem with numerous short side laterals coming.
Cordon like goblet, this training style also utilizes spur pruning. Though instead of head training, one (or two) permanent branch, or 'cordon', on one side of the vine, is trained along a fruiting wire. The cordon is never pruned away and bears eight to nine two-bud spurs.
Spur pruning involves developing a pemanent cordon along the fruiting wire, then trimming the cane that grows from each node of the cordon back to 2 bud spurs. These spurs then produce the canes that provide the fruit for the following season.
Aug 14, 2019 this video describes how to select canes for developing cordons in the transition from cane to spur pruned vineyards.
Chablis system cane pruning, leaving short bud-bearing canes. Cordon system spur pruning on a single permanent ‘cordon’. La taille guyot cane pruning, keeping one cane and one spur per vine (single guyot) or two canes and two spurs per vine (double guyot and asymmetric guyot).
The training system chosen generally dictates how the vines are pruned. Thus, days earlier than the basal buds of the same cane or spur.
Step-wise development of a cordon is recommended for vines planted with in-row spacing of 4 feet or greater, to reduce unproductive gaps on finished cordons. During the cordon development years, a standard cordon length to retain during dormant pruning is five to six nodes, or about 18 inches per season.
Cordon trained, spur pruned vines are ideally thinned to three to five shoots per head training with bilateral cane pruning involves selecting a cane (previous.
Spur pruning is done on vines that retain one or two pairs of long canes (a permanent cordon) trained along a trellis system. Each winter, new canes that have grown along the permanent cordon are cut back to a small shoot containing two buds, known as a spur.
▫ 2nd bearing season – long cane pruning low cordon training.
Spurs spur pruning is done on vines that retain a permanent cordon trained along a trellis.
Unilateral cordon training and spur pruning used when in- row vine spacing is 5 feet or less. Head training and cane pruning used for some culti- vars in cool.

Jul 29, 2020 pruning for this method involves cutting the existing wrapped cane aid in keeping the head compact and at the correct height by spur pruning.
Cordon, or spur pruning, is common in warmer regions and in old vine vineyards. Each year, the vine is pruned back only to its spurs – the little stubs growing out of the canes on which buds appear. As guyot requires a great deal of care, it is uncommon in mass market vineyards.
Nov 1, 2015 in traditional french vineyards each vine is typically pruned to one cane with six to eight buds and one spur with two buds.
Cane pruning is much more labour intensive, and involves selecting the two strongest and well formed shoots on either side of a wine, trimmed to a length which has the right number of buds on each side to produce the grape bunches required, and these two shoots are then wrapped tightly, or wound around the cordon wire to form a cordon cane.
Kendall-jackson winemaker matt smith and kendall-jackson vineyard manager mariano navarro give an instructional talk about double guyot and cordon pruning.
Return to main growing grapes (table, wine, raisins) in your backyard most grape varieties are spur-pruned; that is, the dormant season shoots that grew the previous cut back that cane to create a new spur that has 2 to 3 buds.
While vines that are cane trained will often have a thin, smooth main branch, spur trained vines will often have thick, dark and gnarled cordon branches. Many old vine vineyards will often utilize spur training system. Some examples of spur-training systems include the goblet or bush vine systems, and cordon de royat.
While trunk topping can take place at any time, arm training is usually limited to dormant canes during winter pruning. During the first year, retain long spurs that radiate outwards at the head (≈ top 10 to 15 inches) of the trunk and that are spaced as evenly as possible around the trunk like spokes of a wheel.
Head (long cane) training systems: 4 and 6-cane kniffen can be spur pruned for next 1-2 years.
Cane pruning involves cutting back about 90 percent of the last year's growth.
These will be retained for next year’s cordons and renewal spurs. Remove all other canes and the portion of the cordon past the selected canes. After pruning, from the four canes chosen, select the two healthiest canes on either side of the head and prune to 15-20 buds and tie to trellis for next year’s cordons.
Cane establishment: once the trunk is established and the four selected canes have been secured to the horizontal wires, the first dormant cane pruning should take place. On the bottom two canes, count out from the trunk to four or six buds and prune off the remainder of the cane.
Renewal requires pre-planning: maintain a shoot at the head of the vine (to of trunk) or sucker along the trunk during the growing season for replacing the cordon during winter pruning. Cut out the old cordon by starting from distal portions of the cordon and work toward the vine trunk.
In the cane pruning system, a permanent trunk is established, but the lateral canes are renewed every year. New canes are selected from the head of the vine, at the top of the trunk near the trellis wires.
The various styles of pruning used in commercial vineyards in california may be grouped into three main classes or systems – namely, head, cane and cordon. Head pruning in the head system the mature vine has a vertical stem or trunk, 1 to 3 feet high, bearing at its summit a ring of arms or short branches.
At winter pruning, the dormant cane should be pruned back to a point where the cane is 3/8 inch in diameter. If you have very poor growth much lower than the top of the stake, you should prune the cane back to a two-bud spur and begin training the shoots that grow up the stake in the following growing season.
Grapes must be pruned every year to keep producing because once a cane has are generally trained to have two permanent arms and are spur pruned. Only a few vines and don't want to put up a wire trellis, you can head-train euro.

Only cordon extensions are usually trained from buds on the lower side of the cordon. The canes later undergo pruning, usually spur pruning or, if some fail, rod pruning; for some special varieties and for very high yields- also cane pruning.
Head-trained vines have no permanent cordon, and the trunk ends in a knob, or head cane pruning requires the grower to retain one spur and one cane.
Once the basic architecture of head-training or cordon-training (in whatever exact form it takes) is in place, growers need to decide whether a vine will be cane-pruned or spur-pruned. The canes or spurs are the renewable parts of the grapevine's system and will be replaced via the winter pruning system every year.
Canes from the old wood of the cordon or head are usually not fruitful. A picture of a chardonnay vine pruned to a 3 cane vertical shoot positioning system.
The type of pruning you do will be determined by the variety that you are pruning. There are many different types of training methods but here we will talk about the basics, cane and spur (cordon) pruning. Tricia shows you the different pruning methods in our video winter pruning grape vines.
