Step 6: water thoroughly. water your sweet potatoes frequently and plentifully. container soil always dries out more quickly than soil in the earth. check the moisture of your container soil before watering by inserting your finger into the soil to the second knuckle.

Dig small holes in the container soil, and space them around 12 inches apart. place the slips in these holes, burying them with their leaves. leave a few inches of the top exposed. water the slips well after planting to settle the soil around the roots. keep the soil moist, not waterlogged, in the growing season. 8. plant sweet potato slips in the pot. create evenly spaced trenches in the soil for planting the slips, making sure to plant them deep enough to cover the roots. after planting, water the soil daily to keep it moist but not waterlogged. it’s important to maintain a room temperature or above to ensure optimal growth.
