Look for a location that is away from trees and tall plants to avoid shading. Sweet potatoes grow best in warm conditions, so choose a site that gets lots of warmth and is protected from strong winds. If possible, use a site with a slight slope to improve drainage and sun exposure.
Soil Preparation

Proper Planting Techniques
Prepare your garden bed by loosening the soil about 18 inches in diameter and 6 inches deep to avoid injuring the roots. Cut away some vines carefully to prevent plant damage. Plant the slips 12 to 18 inches apart with the roots and a ½-inch of the stem submerged in the soil.
Water slips daily for the first four days using a liquid fertilizer high in phosphorous to help them root properly. Avoid overwatering as sweet potatoes thrive in well-drained soil. Consider using a seedling heat mat to provide warmth and promote growth.
Use a light, porous soil mix if you are planting in containers. Ensure your container is at least 12 inches deep and 15 inches wide to allow for ample root development. For detailed instructions on planting sweet potatoes, visit GardenBeast.
