Tools needed for kiwi pruning
Before proceeding with the kiwi pruning and all the plants in general it is essential to obtain tools useful for this purpose, learning to use them for a successful operation. In fact, for kiwi pruning it is necessary to have garden shears for all those fragile and small branches, shears for branches that have a diameter that does not exceed 3-4 centimeters, and finally saws for all those branches with a diameter greater than 4 centimeters and that in any case are difficult to cut. It is also recommended to use both tools that are disinfected to the maximum, so as not to cause the kiwi plant pathologies or infections. Finally, it is essential to use tools that are very sharp so as not to cause trauma to the plant due to imperfect cuts.
The kiwi must be pruned during the first two years of planting the plant itself. In fact during this period the plant will have all the time necessary to form a strong and straight stem. The main objective of the training pruning is to create the bifurcation of the branches, which must be two in the case of a pergola shape. In this way all the other jets that will start from the trunk and therefore do not serve the vegetation of the plant will be eliminated. In case of pruning of a male kiwi plant this must be done after flowering, keeping only the shoots that will develop along the trunk. During the training pruning the kiwi plant is unproductive, in fact only after a series of correctly executed interventions will the plant enter production.
The pruning of reproduction of the kiwi plant is carried out either during the winter period or with two interventions, one to be carried out precisely in winter and the other in spring-summer. In the kiwi plant the buds that will be born from branches that are at least one year old will produce fruiting buds. All those branches that have already produced fruit will remain without the following year, for this reason the branches will have to be renewed periodically. After the production of the fruits the plant will enter in vegetative rest, during this pause it is fundamental to remove and reduce the number of the branches. It is advisable to perform winter pruning only when you are certain that there will probably be no sudden cold with frosts and frosts and in any case always before the plant resumes its vegetative activity.
Kiwi pruning: green and renewal technique
With the renewal pruning all those productive branches are eliminated. This operation must be performed every 2-3 years. In fact, after the third year of life and in some cases even after the second year, fruits are produced in very small quantities and of lower quality than those produced previously. With the renewal pruning, therefore, all those weakened, unproductive and therefore damaged pylons will be eliminated during the winter period. Instead with the green pruning, also called summer, we try to favor the penetration of light into the foliage of the plant. Furthermore the interventions deriving from the green pruning allow to shorten and to remove all that vegetation that by now appears to be dry or damaged and all those pylons that prevent an optimal illumination of the inner parts of the plant. The kiwi green pruning operation must be performed during July.
