Your order contains 5 plants. Seon-Mi is a beautiful and historic Korean sweet potato with firm white flesh that is starchier than most varieties. It is an excellent choice for fries, mashing, or making chips. Its potato-like texture makes it a great substitute in warm climates where growing traditional potatoes is difficult. Seon-Mi features attractive pink skin with purple overtones and is prized for its high yields and wonderful flavor. Sweet potatoes have been a part of Korean cuisine for centuries.

Please make sure you are ready for your order in your growing zone, as these young, tender plants generally have no resistance to cold.

Growing Tips:
Seon Mi sweet potato is an heirloom crop that thrives in full sun and grows best in loose, well-draining soil with a pH of about 6.0. Keep the soil consistently moist during early growth, then reduce watering as vines mature. Avoid high-nitrogen fertilizers, which encourage excessive vine growth at the expense of tuber production.

When to Grow

Plant Seon Mi sweet potatoes after the last frost, when soil temperatures reach at least 60 F. This variety is best suited for USDA zones 7-11, where the growing season is long and warm. In cooler climates (zones 6 and below), gardeners can use black plastic mulch, raised beds, or row covers to warm the soil and extend the season. Since sweet potatoes are frost-sensitive, check your local last frost date before planting. If you’re not sure how to find your area's first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Soak the roots in water or wrap them in a damp paper towel to hydrate them. Space the plants 12-18 inches apart in rows 3-4 feet apart. Plant slips 2-3 inches deep, ensuring the roots and lower stem are buried while keeping the leaves above soil level. Mulch with plastic or a thick layer of straw to suppress weeds, retain moisture, and keep the soil warm. Water thoroughly after planting and keep the soil moist as plants establish new roots.

How to Grow

Water consistently during the first few weeks to help plants establish roots. Once the vines spread and mature, they become more drought-tolerant, and watering can be reduced to every few days. You can fertilize with a low-nitrogen fertilizer (such as 5-10-10) about 3-4 weeks after planting to encourage tuber development. Since vines spread widely, make sure that there’s enough space.

How to Save Seeds

  • 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.
  • Follow this comprehensive video guide to curing and storing sweet potatoes over winter.
