Slips are vine cuttings from sprouted sweet potatoes for transplanting to your garden in the spring. Delicious, nutritious, and easy to grow, sweet potatoes are also high-yielding, typically producing more than one pound per plant, and can be stored for months without refrigeration. Sweet potato vine grows practically anywhere, from full sun to full shade. The plant grows best in moist, well-drained soil; if the ground stays too wet for too long, sweet potato vine may rot and die. If you grow it in containers, be sure the pots have drainage to allow excess water to escape. You typically don't have to worry about fertilizing sweet potato vine unless you want it to grow faster.
