You Will Need
- Sweet potato tuber
- Garden plot
- Gardening fork
- Dark, humid storage space
- Sweet tooth
Start your crop early, since sweet potatoes require 100 to 150 days to mature. Begin your slips indoors, about 12 weeks before transplantation.
Grow slips by submerging the bottom third of a tuber in water until it sprouts. Then transfer individual sprouts of 6 inches or longer to their own growing medium to root.
Plant your slips outside when all danger of frost has passed. Transplant into mounds 8 inches high and 12 inches wide, with plants spaced 12 inches apart and rows spaced 3 to 4 feet apart.
Water your sweet potatoes with an average of 1 inch per week, but make sure that the soil is well-drained. Excess moisture will rot the tubers. Stop watering 3 to 4 weeks before harvest.
Care for them
Apply low nitrogen fertilizer and pesticide to limit insect damage.
Harvest your potatoes before frost can damage them. Use a gardening fork and start about 12 inches from the vine’s center, working your way inward.
Leave your crop in the sun to dry for a few hours after harvest, and then move them to a dark, humid space for another 2 weeks to harden. After that, indulge your sweet tooth.
