Can you eat fresh picked sweet potatoes?
Sweet potatoes are delicious eaten right after harvest, but their true flavors deepen as they cure. During the curing process, the starches in the tuber turn into sugar, intensifying the buttery sweet flavor and texture of the potato. Try to minimize any damage to the tuber, as it invites mold, insects, and disease.

How do you take care of a sweet potato vine?
The care of sweet potato plants is similar to most other vining houseplants in the home, spending summers outdoors. While tolerant of drought, these plants prefer to be kept moist (not soggy). Though prolific growers, you may fertilize monthly, if desired, using a general all-purpose, water soluble fertilizer.
How do you prune sweet potato vines?
Cut back vine tips that have exceeded their boundaries. Make cuts roughly 1/4 inch above leaf nodes to encourage new growth. Prune off broken or sickly vines. The more of the vine that is pruned off, the more aggressively the plant will try to regrow.
