The cultivation of sweet potatoes requires high temperatures to thrive and give us a good yield. It shows great drought resistance and is planted and yields in a variety of soil types, with a preference for well-drained, slightly acidic soils with a pH of 5.5 - 6.5.
Sweet potatoes are planted in the field at the beginning of May and grown in rows, in mounds (samaras) spaced 60-80 cm apart. The addition of soil when creating the mound helps to improve drainage and to prevent the tuberous roots of the sweet potato from coming out into the light and turning green.
The sweet potato crop needs regular watering, every 2-3 days, during the summer period when the vegetation is growing and tuberous roots are forming, and when the sweet potato harvest season is approaching, watering is reduced in both quantity and frequency. Sweet potato cultivation is not particularly demanding in terms of fertilisation and nutrients.
The sweet potatoes are harvested 4-5 months after planting, i.e. in September and October.
