When to Plant Sweet Potatoes You won’t plant slips until 3 to 4 weeks after the last spring frost, once nighttime temperatures have reached at least 55°F (13°C). The trick is to plant them early enough for them to mature properly, but not early enough for them to get killed by a late spring frost.
Are sweet potatoes OK if they sprout?
