Sweet Potatoes are a warm-season crop that grows best in long, hot growing seasons, preferring fertile, well-drained soils. Sweet potatoes are members of the morning glory family, are relatively pest free, and can be stored for a long time after harvest.
Growing Sweet Potatoes
Sweet potatoes are classified as either soft-fleshed or firm-fleshed. The soft-fleshed varieties are sweet, have orange flesh and are often called yams. The firm-fleshed varieties have light orange, yellow or even white flesh and can be stored for longer periods of time. Beauregard, Bush Porto Rico, Jewel and Sumnor are a few of both varieties that grow well in Utah.
Sweet potatoes grow best in all soil types provided they are fertile, moist, well drained and nutrient rich. Centennial is a clay tolerant variety. Before planting, incorporate 4 to 6 inches of well-composted organic matter and apply 1 to 2 lbs of all purpose fertilizer per 100 square feet. Work fertilizer into the soil to a depth of 6 inches.
