Plant braces and ligatures
The use of structures such as guardian poles is necessary in the case of newly planted trees that already have a fair size. There is a risk, in fact, that they are uprooted by climatic agents or, more simply, that the clod is moved with consequent damage to the roots. However the use of a guardian has as consequence the production by the plant of a less solid trunk, not able to withstand strong solicitations once its support is removed. This is because the plant is not stimulated to build a solid structure of its own. Therefore it will be good to use low braces, so that the tree is tied to a minimum height and has a certain capacity of movement for the crown. Usually one, two or three poles are used: in the first case it will be positioned on the opposite side to the direction of the wind, with an “8” ligature that guarantees the distance from the trunk, if instead the poles are two will be enough a ligature at the ends, while three poles also allow greater protection from mechanical shocks. In the case of trees of considerable diameter, wire ropes can also be used connected to pegs planted in the ground and to textile strips that wrap around the trunk. Check all the support systems during the growth of the tree, so that it is not damaged, for example with too tight ligatures. In any case, after one year the braces must be removed because in the long run they affect the tree's self-support capacity.
