Where is the best place to plant sweet potato vines?

Choose a sunny site with rich, well-draining soil. They prefer hot, humid conditions similar to their native habitat and may fail to thrive in dry desert climates. In cooler regions, boost performance by planting in a warm location such as a south-facing wall or heat-absorbing patio.
