Potato cultivation

Sowing potatoes

For the cultivation of potatoes we will have to get some specimens of the previous harvest. We will favor organic potatoes that sprout more easily and are safer from a food point of view. We can also decide to keep the species that we consider best to renew the cultivation the following year. The important thing is that the potato is equipped with at least a couple of small sprouts that will sprout spontaneously leaving it to rest for a few days. Then we can bury it with the shoot strictly facing upwards. Wanting to follow the ancient traditions, the potato should be sown during the waning moon phases. The classic cultivation of potatoes involves parallel furrows, spacing the potatoes by about 30cm from each other, at an ideal sowing depth of at least 12cm.

Irrigation in potato cultivation

In the cultivation of potatoes we will have to be very careful to keep the degree of soil moisture as constant as possible. When the potatoes are sown we must immediately work by wetting the soil generously to facilitate the sprout to come out. With the small plant at home the watering interventions will be less frequent and it will grow naturally. When the plant is developed we will have to intensify the irrigation operations. Of course, it all depends on the region in which we grow it and the specific climate. The atmospheric precipitations, in the rainy seasons, can also satisfy the needs of the potato. As the months get warmer, watering must be regular and abundant, without however exaggerating. For larger crops it is useful to evaluate the

Soil and cultivation techniques

Before growing potatoes we will need to properly prepare the soil. The potato needs fertile land and a worked substrate to allow the tuber to grow freely, avoiding the formation of clods. It will be necessary to proceed with a deep digging, digging for at least 45cm. For medium and large crops, the use of motorized vehicles is recommended. Fertilization can be done by adding mature manure and well-decomposed natural compost. The enrichment of the earth must be carried out a few months before sowing, starting in the previous autumn, so that the substances contained in the fertilization are correctly absorbed by the soil without coming into direct contact with the tuber. During the growth phase we will have to operate periodically by removing the weeds.

Potato cultivation: Exposure, climate and diseases

The best areas for growing potatoes are characterized by a climate where the winter is quite harsh and long while the summer is not particularly hot nor, above all, drought. Cool summer would be the optimal condition to reduce artificial irrigation interventions and maintain a constant water supply. Therefore the potato, in addition to adapting to be grown in all regions of Italy, prefers hilly areas. It can also be successfully grown in the mountains. The potato can be attacked by dangerous fungal diseases and parasites. The fungi that affect it cause spots on the leaves. The best known parasite, on the other hand, is the doriflora. To prevent these attacks, a pyrethrum-based remedy can be used, thus avoiding ruining the entire crop.
