This training system was developed in the 1980s by the Czech viticultural expert Vilém Kraus (1924-2013), derived from the vertical cordon training practised earlier. It is suitable for certain grape varieties on steep slopes, such as Blauburger, Grüner Veltliner, Pinot Blanc, Pinot Noir, Riesling and Rotgipfler. However, it is not suitable for the varieties Blaufränkisch, Dornfelder, Blauer Portugieser, Sauvignon Bl anc, Traminer. In the Vertiko planting system, a cordon arm is built up vertically on a trunk of 80 to 90 cm in length up to a height of 160 cm (which gives the name = verticallyraised cordon arm).
On this vertical cordon of 70 to 90 cm length, tiers with several one- to two-eyed cones are cut at intervals of approx. 25 to 30 cm. The growing shoots then hang down freely and must be pruned up to three times. The row distance must be at least 2.5 m, better 3 m. A sturdy wire frame with one or two strong tension wires serves as support. This form is occasionally used in Germany (e.g. along the Moselle), Austria and the Czech Republic. Due to the high proportion of old wood, there is an increased susceptibility to anthracnose and increased infestation by mites. Another disadvantage is uneven growth in the upper and lower cane areas. This is why the system has not yet really caught on. The system belongs to the large group of so-called cordon training systems. See also lists at vine training (systems) and vineyard maintenance (activities).
