These are different methods to direct the growth of the vine in a specific way. The vine is a climbing plant (liana) that cannot keep itself upright and therefore needs a climbing aid or support structure. The wild vines usually climb up young trees and grow upwards with them. For longer cultivation and in order to be able to use machinery, the vines must keep their shape and not (which they would do) grow higher and higher. Thousands of years ago, man therefore began to shorten the shoots and use artificial support devices such as poles or sticks, frames and slats with taut cords or wires. A decisive measure during the winter break (resting period) is pruning, during which the annual wood is cut. With annual measures (winter pruning, summer pruning and foliage care) the effects of apical dominance are counteracted in order to maintain the chosen educational system.
