Potatoes are plants originating from South America, with a high content of vitamins and carbohydrates in the face of low caloric intake. Their cultivation requires a wider space than that of normal garden beds, which must be fertilized with mature compost and manure. Potatoes love soft, humus-rich earth and must be planted in the first round of rotation. The period of burial varies from March to April, while in regions with a particularly harsh climate it is possible to arrive until May, in any case when the soil temperature reaches 7 °. Trace the furrows at a distance of 40-50 cm, while the plants must be separated for 30-50 cm and placed in the ground for 5 cm. Then refill the rows of mature compound and close the grooves. Keep the earth moist and free of weeds, being careful not to damage the growing tubers. When the aerial part begins to wither it is a sign that the maturation has come to an end, something that generally occurs from mid-June to August-September. Keep the tubers collected in dark and cold places so that they do not sprout or produce green parts containing solanine, a toxic substance.
