Choose a sunny location with loose, well-drained soil
Prepare the soil by removing rocks and weeds
Mix in compost if needed
Wait until the soil is warm and frost risk has passed
Buy healthy sweet potato slips
Make rows or mounds for planting
Space slips about 12 to 18 inches apart
Plant slips deep enough to cover the roots and lower stem
Water the slips immediately after planting
Keep the soil evenly moist until the plants are established
Mulch lightly to help retain moisture and reduce weeds
Avoid over-fertilizing with nitrogen
Weed carefully around the plants
Let the vines grow without disturbing the roots
Harvest when the leaves start to yellow and the roots are mature
Cure harvested sweet potatoes in a warm, humid place before storing
