Vertical Cordon ("Columnar Vines" / "Schnurbaum")

This form is particularly suitable for narrow, vertical areas and / or if quality of table grapes is to be very high. What may look rather rigid and somewhat unnatural at first glance, soon enough surpasses any other "free" espalier form: there is no tedious sorting of shoots, pruning becomes a routine and the stem framework remains very manageable.


This training method originates most probably from France and was described for Germany by Hardy / Jäger in their work "Obstbaumschnitt" ("Fruit Tree Pruning") as "Herzstamm" ("Heart Stem") in Erfurt in 1855.

Spatial Requirements

Not including the planting area, each cordon needs a wall area of approx. 0.6m x 1m, max. 1.5m x 2.5m. For wider areas, several vines are planted, spaced at approx. 1.5m centres. For high walls, several cordons are trained to staggered heights (see diagrams below).

Trellis Systems

Requires a vertical wire rope, but better three wire ropes (spaced 30 - 40cm apart), to allow young shoots to twine or be tied to wires on both sides. For very narrow areas, use 2 wire ropes and guide the shoots to one side only (see photo). Timber trellises are suitable as well.

Training and Pruning

Refer to diagrams. The yearly vertical extension is about 50 to 80cm, ie approx. 4 new side shoot positions. In the end, there will be max. 8 - 12 side shoot positions or a max. distance of about 2m between the lowest and highest canes, otherwise the lower shoots will fail. The trunk will end approximately 50cm below the top of the trellis. Once the training is finished, Spur Pruning follows. Ideally the green shoots are either tied to or tucked behind the single / two outer wire ropes. The uppermost side shoot position requires Rod Pruning, because growth is very vigorous there. At a later stage and over the course of 2 - 3 years switch to Cane Pruning of several side shoot positions (see diagrams below), starting from the uppermost cane down to the lowest, leaving only about 4 - 6 side shoot positions per cordon and increased distance between the individual tiers. To be foIlowed by Summer Pruning if necessary.

3rd Year

Diagram 04: The 4 lower canes are spur pruned, the upper one is used to extend the cordon, pruned back to 5 eyes and tied to the wire.
Diagram 05: After winter pruning
Diagram 06: Bud burst in spring. At the end of August, the shoots can be trimmed back to approx. 1.0 to 1.5m to ensure maturation of the lower buds.

4th Year

Diagram 07: Trimming back the upper, newly grown side shoots to spurs and the leader to 5 eyes.
Diagram 08: Removing superfluous canes and stubs of older spurs. Usually the cane further away from the main trunk is cut off completely.
Diagram 09: Pruning the remaining canes back to spurs with 2 eyes.

Diagram 11: After winter pruning: if by then, the final height of the vine has been reached (see above under "Training and Pruning"), then the leader is also shortened to 2 - 3

Switch to Cane Pruning

Form 01: Alternating Pruning: the pruning type for each cane switches every year from spur to cane pruning and vice versa ("Alternating Pruning"). This gives the canes - which may have weakened by cane pruning and high yields - a chance to recover during the following year, and once again produce strong canes for another cane prune.
Form 02: "Arched Canes": Here some canes have already failed, the remaining canes were cane pruned and - because the wires were horizontal - very slightly bent and tied to the wires. "Back-up" eyes on the shoot positions are not required, because usually all eyes on these slightly bent canes grow equally strongly, producing strong canes close to the shoot position for the following pruning.
Form 03: "Semi-Circular Canes": Here the canes of all side shoot positions have been bent and tied into "semi-circular arches," because the supports are vertical. This way, the shoots from the many buds grow at different heights, which makes for a better spatial distribution of the grapes than on the shallow arches, and the grape bunches will not be too tightly packed. The distance between the side shoot positions on each side should be at least 60 - 80cm.

Other Varieties

Combination of alternating cordons (varying heights) and palmette (several parallel arms) with spur pruning. For a system with cane pruning, the distance of 1.5m between vines needs to be increased to about 2m. If necessary, the arms of the two double palmettes can be trained close together so that there are only 2 main cordons instead of 4 (see inset top right), and the vines can even be planted into the same planting area ("quiver style" planting).
For taller heights or if a greening area is to be covered quickly, cordons of alternating heights - each developed in their individual tier - are useful.
