Maintain the soil and the room at 75☏ to 80☏ in sunlight or under artificial lights.Water now and as needed to keep soil damp but not soggy. Lightly cover with a few inches of additional soil.Leave an inch or two of space between each sweet potato.

Stick the roots in water for a day or so and they’ll perk up. Plant them as soon as conditions are right. If you ordered slips from a mail-order source, unpack them right away. Cover them with plastic milk jugs or use row covers, removing the covers during the day. Be sure to protect young sweet potatoes from any late frosts or cool nights (lower than 55☏/13☌), as they are very tender. The trick is to plant them early enough for them to have time to mature fully, but not so early that they get killed by a late spring frost. Nighttime temperatures should be at least 55☏ (13☌). Plant slips outdoors 3 to 4 weeks after your last spring frost or once the soil has warmed to at least 65☏ (18☌). Also avoid heavy nitrogen fertilizers, which produce lush leaf growth at the expense of the edible roots!

They will grow in the North (even parts of Canada!), when grown in sandy soil or raised beds that are mulched with black plastic to keep the soil warm. Although traditionally more of a Southern crop, there are many short-season varieties of sweet potato today.

#Sweet potato skin
This root vegetable has deep-orange flesh and a coppery skin jacket. Another difference between sweet potatoes and “standard” potatoes is that the edible portion of the sweet potato is a tuberous root, not a true tuber (which are technically modified plant stems). Compare a sweet potato vine’s foliage and flowers to those of a morning glory and you’ll see the family resemblance! Despite their name, they are not related to potatoes, which are in the nightshade family. The sweet potato is a tropical plant and a member of the morning glory family.
