When to Plant Sweet Potatoes The trick is to plant them early enough for them to mature properly, but not early enough for them to get killed by a late spring frost. Before planting, make sure you have a long enough growing season. Most varieties will take about three to four months to mature – about 90 to 120 days.

How many sweet potatoes do you get from one plant?
Sweet potatoes are grown from rootable cuttings, often called slips. If you’ve never grown sweet potatoes before, it can be great fun to grow your own slips from small or medium-size sweet potatoes purchased at the market. One sweet potato will produce between three and five slips.
What’s the fastest way to grow a sweet potato?
Faster “soil method” of making sweet potato slips
- Poke holes in the bottom of a foil pan.
- Fill foil pan with potting soil or seed starting mix.
- Moisten soil.
- Nestle sweet potatoes in soil, covering about half the potato with soil.
- Place the lid under the pan to catch any excess water coming out the holes.
How long does it take for a sweet potato to sprout?
Most commercial producers figure on 1000 slips per bushel, but if you’re doing this at home, a good rule of thumb is 10-15 slips for every root around 1-2 inches in diameter (If the roots are eating size figure on about 6 slips per root). It will take about 4 weeks to sprout your sweet potatoes.
Can you grow a sweet potato from a sweet potato?
You can start your own slips, sprouts from an existing sweet potato, by purchasing “seed” sweet potatoes from a nursery; or you can start slips from tubers purchased from the grocery store. Some sweet potatoes may be sprayed to inhibit sprouting, so be careful to choose organic tubers.
How do you know when it’s time to dig up sweet potatoes?
Sweet potatoes are usually ready to harvest just as the ends of the vines begin to turn yellow, or just before frost in the North. To avoid injuring tubers, find the primary crown of the plant you want to dig, and then use a digging fork to loosen an 18-inch wide circle around the plant.
How often do you water sweet potatoes?
Once established, sweet potatoes will tolerate growing in dry soil. It’s best to keep it evenly moist with 1 inch of water given once a week.
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!
How deep do sweet potatoes grow?
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 just plant a whole sweet potato?
“Slipping” is when you grow little baby plants out of a whole sweet potato. Now, you can just bury whole sweet potatoes very shallowly if you like, but many gardeners prefer to grow slips from the tubers and then plant the slips. It’s easy, fun, and one of the best gardening activities for kids.
How do I encourage sweet potatoes to sprout?
Place sweet potatoes in a glass jar of water. You want half of the sweet potato under water and the rest not. The part under water will grow roots and the part above water will grow sprouts (known as sweet potato slips).
Can you cut up a sweet potato and plant it?
Or you can start your own. One way is to cut the sweet potato in half lengthwise and lay it cut side down in some moist potting soil. After a time the sprouts will start to grow. In just a couple of weeks you’ll have several sweet potato slips, fully rooted and ready to plant.
Why did my sweet potatoes not produce?
Sweet potatoes will be overly stressed if they get too dry, and a stressed plant will not put energy into tuber growth. Like the rest of your garden, about 1” of water a week is a good guideline.
Can you eat freshly dug sweet potatoes?
You should resist the temptation to dig and immediately eat sweet potatoes, as fresh ones are more starchy than sweet, and don’t bake as well as cured ones. Wait at least three weeks before eating, so the starches can convert to sugars. Sweet potatoes can last six months or more in storage, if held properly.
Do sweet potatoes grow underground?
Like regular potatoes, sweet potatoes are starchy tubers that form underground. Sweet potato plants are sensitive to cold, so they should not be planted outdoors until the soil has warmed to at least 60 degrees F.
How do you start sweet potatoes indoors?
Plant the sprouting sweet potato in a container of well-drained potting mix. Plant it with the growing point just below the soil surface or lay it on its side and cover with potting mix. Grow your new plant in a sunny window and water as needed. Sweet potatoes make a great indoor plant.
