Quality viticulture, among other things, requires proper leaf wall management.

The basic goal is to be able to obtain a leaf wall of sufficient size (balanced vegetative-productive ratio), with an upright habit and always with a share of young, physiologically active leaves.

This type of setting usually requires the need to make at least two passes to properly raise and direct new vegetation in the spring-summer period.

Therefore, solutions were sought that combined economy of execution and quality of execution.

In this regard, the use of movable wires to accompany vegetation growth is becoming more widespread; these wires can be moved either with appropriate operating machines or manually.

The use of the machine is attractive mainly for large areas, and good quality of work can be achieved only under certain conditions (upright cultivars, reduced vigor and timeliness of execution).

Metal poles are an excellent solution both for those who use the machine and even more so for those who move the wires manually; in fact, with metal braces there is no need to apply no accessories to the pole (expensive and cumbersome) and you can accompany the vegetation according to its growth gradient being equipped with many positions.

The choice of the number and location of wires in the vineyard structure depends on many factors including the bearing and vigor of the cultivar, the fertility of the environment, and the size of the leaf wall to be set up.

In graphs A,B and C three examples of structures have been given.
