Kiwi cultivation

Kiwi: how to choose where to plant it and in what quantities

The term dioecious means that some kiwi plants are male, and are used for pollination; while others are female and produce kiwi fruit. To ensure that they grow luxuriantly, therefore, there is the need to have both the male and the female plant. If the space available to cultivate them is limited, a couple of these two should be preferred; if, on the other hand, you can take advantage of a lot of space, then it is good that the kiwi plant can lean on a pergola, a wall or any other type of support or tutor. Kiwi branches are powerful and need strong support to be supported. If the cultivation can extend over a large land, it will not be necessary to alternate male and female, it will be possible to plant even more female kiwis (about five) interspersed with a single male.

Kiwi: suitable climate and cultivation

The kiwi grows luxuriantly in a shady and humid climate: it fears frost, and for this reason the ideal period for its planting is spring. A useful tip is to keep it away from winds, which dry out the soil in which it sinks and could even damage the branches. The plants must be positioned at a distance of 2 meters from each other, in a rich soil or enriched with peat and sand: it is then necessary to add mature manure every 2 or 3 years, between the autumn or winter period to fertilize. It is also necessary to guarantee the cultivation of the kiwi a net that overhangs the plant, which acts as a barrier to the sun’s rays and prevents frequent recirculation of air, so that the humidity level remains adequate and fruiting takes place correctly. In addition, it must be repaired from too low temperatures: during the winter, the ideal would be to cover the crops to favor their protection. As for the irrigation of the plant, it is good that the soil is always wet, so it must not be forgotten during the summer.

Kiwi: harvesting the fruit

Once placed in the right soil, therefore not calcareous and with a sufficiently acidic pH, the kiwi plant will begin to bear fruit about three years after it has been decided to plant it, mainly in the autumn-winter period. After harvesting the fruit, it is advisable to lightly prune all the branches that have fruited within the crop. If you notice that the vegetation is getting too dense and that the plant is in danger of not being sufficiently ventilated, it may also be necessary to cut the tallest branches vertically after flowering, which occurs during the summer period. Attention: if some of these operations are omitted, it is very likely that after a short time the plant will take on a tangled appearance, which would make it difficult for the future harvest of the fruit and put its health at risk.

Kiwi cultivation: Kiwi: plant diseases

Like any vegetable, even the kiwi plant can get sick and suffer the pathogenic action of some bacteria present in nature. One of the most feared diseases is the so-called Kiwi bacteriosis, caused by the bacterium Pseudomonas Syringae Actinidiae (PSA). It can be recognized immediately thanks to the color it gives to the flowers and fruits: they tend to become darker, first brown and then black, curling up on themselves and withering. The leaves suffer the same fate, first they turn yellow and gradually darken, leaving however a yellow halo to surround the dead zone. The branches, trunks and tendrils are also affected, filling with infected areas that produce a reddish (liquid) exudate. To prevent the plant from getting sick, it is necessary to dedicate the above care to it, with particular attention to the soil, irrigation, pruning and even fertilization. Furthermore, a careful and constant observation of the specimens in cultivation is very important.
