Plant your slips at least 2–3 inches deep (2 or more nodes) with at least 2 leaves above ground. Space 10–14 inches apart in rows at least 3 feet apart, to make room for the sprawling vines. Wide in-row spacing leads to larger tubers. In hot weather, transplant in the evening.

How deep do you plant sweet potato slips?
Sweet potatoes mature in 90 to 170 days and they’re extremely frost sensitive. Plant in full sun three to four weeks after the last frost when the soil has warmed. Make holes 6 inches deep and 12 inches apart. Bury slips up to the top leaves, press the soil down gently but firmly, and water well.
Can I plant sweet potato slips directly in soil?
Start sweet potato slips 6 weeks prior to planting out. Rest a whole, undamaged sweet potato in soil and set on a heating mat. Slips will start to grow in around 2 weeks. Rooted AND unrooted slips can be planted directly in the soil.
When should I plant my sweet potato slips?
When to Plant Sweet Potatoes
- Sweet potatoes are not grown from seed.
- You won’t plant slips until 3 to 4 weeks after the last spring frost, once nighttime temperatures have reached at least 55°F (13°C).
- Before planting, make sure you have a long enough growing season.
Do sweet potato slips need roots before planting?
Before you plant sweet potato slips, you have a little extra work to do. Sweet potatoes need loose, well-drained soil to form large tubers. You don’t want the roots to face resistance when they try to expand within the soil.
How long does it take for sweet potato slips to sprout?
As long as the soil is kept lightly moist, the slips will develop roots and start growing within two weeks. Six weeks after that, the sweet potato vines will explode with growth and cover the ground with dense foliage.
Can you plant a whole sweet potato in the ground?
Planting whole sweet potatoes will give you vines and roots, but — because the resulting vines are so close together — the roots you harvest will tend to be stunted.
Which end of the sweet potato goes in the water?
Place the sweet potato in a container of water. Keep the top 1/3 of the potato exposed by placing toothpicks into the sides. The pointed end should be down in the water. In a few weeks a vine with several stems will begin to sprout.
How long can you keep sweet potato slips in water?
Take the slips from the sweet potato root by twisting them while tugging on the slip. Once you have the slip in hand, place it in a glass or jar of water for about two weeks, until fine roots have developed on the slip.
How much sun do sweet potatoes need?
They enjoy full sun (at least 6-8 hours during the growing season) and thrive in loose, well-drained, nutrient-rich soils – although they will tolerate almost any planting site. Select and prepare the planting site for the benefit of your sweet potato plants so that, come harvest, you get a bountiful crop!
Can I plant a sweet potato that has sprouted?
No, you should not plant an entire sweet potato that has sprouted. Instead, you should wait for the sprouted parts to grow longer and develop roots. Don’t plant the entire sprouted sweet potato – wait until the sprouts develop roots and turn into slips. Then, you can remove them and plant them!
