Sweet Potato Plants, Nancy Hall
Description
(Ipomoea batatas). Your order includes 5 plants. Nancy Hall is an heirloom sweet potato with deep roots in the southeastern U.S. For decades, it dominated the commercial sweet potato market, and was once so popular that in 1939 the folks in Paris, Tennessee, held a “Nancy Hall Sweet Potato Jubilee.” It’s not clear how this potato got its name; one story from the late 1890s claims that it was an accidental cross of potato and flower seeds by Miss Nancy Hall. Regardless of its origin, the Nancy Hall has firm, golden flesh and tan skin, and while it never grows to gargantuan size, the 4- to 8-inch-long tubers keep well and deliver superb flavor. This historic variety is included in the Slow Food Ark of Taste, and it deserves to be grown and preserved!
Please make sure you are ready for your order in your zone as these young, tender plants generally have no resistance to cold.

Growing Tips, Tricks and FAQs
Growing Tips
Nancy Hall sweet potato is an heirloom crop that grows best in well-draining soil and full sun. Unlike traditional seed-grown crops, sweet potatoes are grown from live slips (rooted plants). When your slips arrive, hydrate them by soaking the roots in water or wrapping them in a damp paper towel before planting. Since sweet potatoes are cold-sensitive, you may need to pot them up in a protected area until all risk of frost has passed. If the weather is already warm enough, you can plant them right away.
When to Grow
Plant Nancy Hall sweet potatoes outdoors only after all danger of frost has passed, when soil temperatures are at least 60 F. In northern climates, using black plastic mulch can help warm up the soil. Since sweet potatoes are frost-sensitive, be sure to check your local area’s last frost date before planting. If you’re not sure how to do that, consult our blog post ‘Our Experts Answer Questions, Share Resources.’
How to Sow and Plant
Plant the slips 12-18 inches apart in raised beds or rows. Plant slips 2-3 inches deep, making sure that the roots and lower stem are buried while keeping the leaves above soil level. Mulch with black plastic or a thick layer of straw to suppress weeds, keep the soil warm and retain moisture. Space rows 3-4 feet apart to allow the vines to spread freely. Water well after planting to help the slips establish strong roots.
How to Grow
Water 1-2 inches per week while young, keeping the soil moist but not waterlogged. As the vines spread and mature, reduce the watering to every few days. Avoid over-fertilizing with nitrogen, as this will encourage excess vine growth instead of root development. Harvest after 90-120 days, when the leaves begin to yellow and die back.
How to Save
-
Sweet potatoes are not propagated by seeds, but rather by saving tubers over the winter in a cool, dark place to replant the following spring.
-
Be sure to select the most healthy tubers for replanting.
