Wisteria pruning

The development of wisteria

Wisteria is a decorative plant that comes to us from the East, from the areas of China and Japan, and which in a short time has conquered European gardens and green spaces for the charm of its flowers and its intense perfume. It is a shrubby plant with great decorative potential, as it is characterized by dense inflorescences of varying color between blue and the different shades of purple and lilac, which develop in a very generous way. This feature can be interpreted as a double face of the wisteria, which is suitable to become the visual center, imposing and majestic, of the gardens, but which, on the other hand, requires a lot of attention from the point of view of pruning. If, in fact, for most plant species pruning is an operation recommended for plant health, for wisteria it becomes essential to be able to control its development and give shape to what would otherwise become a shrub of great intrusiveness. ThereWisteria pruning is therefore carried out at different times of the year and the operations to be carried out vary according to the life phase of the plant, which in the first years will need to be directed towards growth and subsequently mainly contained.

Summer and winter pruning


The main pruning operations that are carried out every year on wisteria specimens are essentially two: the most decisive will be the summer pruning, when the plant is in the middle of its vegetative cycle and tends to develop in a decisive way. In winter, pruning will instead have a containment purpose and will also serve to select the branches from which we want the development of the plant to continue. Summer pruning is carried out by shortening the branches of the previous year, leaving them about one meter long: these will be the branches that the following year will give rise to the buds after having lignified. In this way we will intervene on the shape of the wisteria, eliminating the branches that are too long and preventing the younger ones from developing irregularly. This selection, made from year to year, will allow to keep under control the shape assumed by the plant. With winter pruning, on the other hand, the aim is to reinvigorate the plant: we only intervene when the wisteria has lost its leaves, therefore in late winter, and the younger branches are cut, leaving only four or five buds that will later develop. Winter pruning is also the right time to eliminate the driest, old and unproductive branches that steal nourishment from the plant without being useful for its effective development.

Formation pruning and green pruning


Pruning, as mentioned, must also adapt to the different life stages of the wisteria, in which the plant will have different needs. The first years of life are those that see the wisteria subjected to the most intense growth, therefore they are the most important from the point of view of the attribution of the shape of the plant. For this reason, we speak precisely of training pruning and we must take into account not only the space available to the plant but also the structure that you want it to assume, to then develop further without undergoing too many variations. On the other hand, when the wisteria begins to age, pruning will be more useful for containing the development of the green rather than its structural expansion: in these cases we intervene by eliminating the branches that are too dense or that grow too shady,

Pruning wisteria: Give shape to wisteria


One of the most fascinating elements of wisteria is its incredible versatility from a structural point of view: being a climbing plant it can take on the most diverse shapes and decorate any space. The wisteria therefore needs, in order to grow, a stake on which to develop: it is frequently used to decorate pergolas, terraces, porches, creating a flowered roof of great romanticism. However, wisteria does not necessarily have to be used in such a way as to grow imposing: it can also be more contained and cultivated in such a way as to grow around columns or even on the ground, as a bush to which to give the most pleasant form: in these cases the pruning will have to be more decisive to give life to palmettes or bushes. For the bush wisteria, however, it is necessary to remember to position the plant sufficiently distant from all the others: otherwise there is a risk that the wisteria will be able to reach and climb on them. One of the most fascinating crops is the one with another tree as a tutor: if the flowering is contemporary, once the wisteria has grown enough and the branches of the two plants are intertwined there will be a splendid two-colored flowering. In the case of wisteria, in fact, the host plant does not suffer particular damage or weakening despite the presence of wisteria, especially if a host plant with sparse branches is selected, so that the intertwining does not cause poor lighting for the branches of neither species. otherwise there is a risk that the wisteria will be able to reach and climb on them.
