The sweet potato is a vegetable originating from tropical regions and is very appreciated for its slightly sweet taste and its sparkling colour. Appreciated as a starter, dish or dessert, the sweet potato seduces young and old. It is a source of many nutrients: vitamin A, antioxidants,... Very low in calories, it is an excellent alternative to the classic potato. The sweet potato belongs to the convolvulaceae family. The varieties that are most common in France are Bonita (white flesh), Murasaki (white flesh with a slight nutty taste), and Evangeline (orange flesh, very sweet).
The plantation in ground in your kitchen garden is to be privileged but its culture must be prepared very early in the year. The sweet potato appreciates fresh, rich and deep soils, and is to be planted in spring. Exposure to sun and heat is necessary for the cultivation of sweet potato. It requires temperatures above 20°. However, if you choose to sow ornamental varieties, to decorate your garden, they can tolerate semi-shade exposure.
The tuber does not appreciate dryness, it is necessary to take care to water it very regularly, in particular during the summer periods. The sweet potato is very resistant to diseases. The cutting of the sweet potato is simple: it is enough to take a young growth and to transplant it. As for the timing of the tuber, harvesting takes place after flowering, about 4 to 6 months after planting. The sweet potato can then be stored in a cool, dry place.
