The crop was introduced to China in the late 16th century and spread through Asia, Africa, and Latin America during the 17th and 18th centuries.

How They Grow

Growing Sweet potatoes-know your vegetables by Green Blender

Sweet potatoes come in two forms: vining and bush varieties. Both types thrive in the hot summer sun and are relatively easy to grow. They are a tropical vine, and are sensitive to the cold, so it is best to plant them during the summer. To begin, it is best to plant slips, which are the green shoots from a mature sweet potato. Slips can be purchased at a garden store or nursery.

Before the slips are planted, it is recommended to till the area of the garden where they will be planted to a depth of 8-10 inches. Once tilled raised beds of 6 to 8 inches tall and about 12 inches wide should be created. The slips are planted in the bed and should be about 12-18 inches apart. It is best to plant the slips deep enough to cover the roots and about 1/2 inch of the stem. Sweet potatoes should be watered regularly and should be ready to harvest within 3-4 months after planting.
