Vertiko

This educational system was developed in the 1980s by the Czech viticulture expert Vilém Kraus (1924-2013), who derived it from the vertical cordon education that had been practiced earlier. It is suitable for certain grape varieties such as Blauburger, Grüner Veltliner, Pinot Blanc, Pinot Noir, Riesling and Rotgipfler on steep slopes. It is not suitable for the varieties Blaufränksich, Dornfelder, Blauer Portugieser, Sauvignon Blanc, Traminer. On a trunk of 80 to 90 cm length a cordon arm is built up in vertical extension up to a height of 160 cm (which gives the name = vertically raised cordon arm).

Vertiko-Erziehung = vertikaler Kordon

On this vertical cordon of 70 to 90 cm length, tiers with several one- or two-eyed cones are cut at intervals of approx. 25 to 30 cm. The growing shoots then hang down freely and must be shortened up to three times. The distance between rows must be at least 2.5 m, better 3 m. A stable wire frame with one or two strong tension wires serves as support. This form is used sporadically in Germany (e.g. on the Moselle), Austria and the Czech Republic. Due to the high proportion of old wood, there is an increased susceptibility to anthracnosis and increased infestation by mites. A further disadvantage is an unequal growth strength in the upper and lower cane area. For this reason, the system has not yet been properly established. The system belongs to the large group of the so-called cordon-education systems. See also listings under Educational system (systems) and vineyard care (activities).
