Burying a sweet potato can cause it to sprout new vines (slips) that can be planted for a new crop, but the original potato might also rot, especially in cool soil, as they prefer warmth. For best results, you should encourage sprouts (slips) to grow first, then cut them off and plant them in warm soil after the last frost, rather than burying the whole tuber, which can lead to overcrowding and disease, notes Piedmont Master Gardeners.

Once they are full size and have a few leaves, break the stem off the sweet potato and place it in a container filled with moist potting soil. The stem should be buried an inch or so in the potting soil. But take care to keep the leaves above the soil level. This process allows the slip to form roots.
If a whole sweet potato is placed in the ground in early spring — when white potatoes are usually planted — the cold weather will inhibit its growth and it might rot. For this reason, the recommended propagation technique for sweet potatoes is to plant “slips” after the last frost date.
like regular potatoes, if they're not organic they're sprayed with a sprout inhibitor so they don't sprout in the grocery store. Sweet potatoes also like a hot soil (85-100 degrees) ; if you live in a cooler growing zone, try heating up the soil with some heavy clear plastic over your plants. I love your videos.
Dig a shallow trench about 6-8 inches deep. This can be done with a rake in loose soil, but you may need a shovel or hoe in heavier soils. Place cut potatoes 10-12 inches apart in the trench. If larger potatoes are planted whole they will produce larger plants and should be given a little extra room, 12-16 inches.
Keep the plants free of weeds until they can shade out competition. Cultivate carefully to protect the shallow roots. Side dress each plant with a shovel full of compost for better yields and larger sweet potatoes, though sweet potatoes generally produce well even with low fertility.
Yes, you can plant potatoes in September for a fall/winter harvest, especially in warmer climates or as a "second crop," but success depends on your local climate and the potato variety's maturity time; you need enough cool, moist weather for tuber development before hard freezes, using mulching and quick-maturing varieties helps ensure you harvest before winter weather sets in.
And a second hidden bonus is, often the overwintered vines will grow tiny sweet potatoes over the winter months, and you get to harvest these again in the spring when you prepare fresh cuttings and vines for your summer season!
You can certainly plant the whole potato. Although, it'll cause overcrowding in a small space. If the space is provided, cut in between each shoot, then plant each shoot with about 12” inches in between. Then you'll produce more potatoes.
Instead, they grow them from small sprouting potatoes. Any potato, with sprouting eyes, that's at least the size of a chicken egg has the means to yield up to five pounds of fresh potatoes (Generally speaking, the smaller varieties of potatoes grow to maturity faster but yield less harvest.)
I like to let them go a little bit longer and keep them in the ground until the first frost or two. This gives them even more time to grow large. If possible, dig up the sweet potatoes when it has not rained for three days.
Two days before planting, slice larger potatoes into smaller pieces. Each piece should contain at least one eye or bud. You can plant potatoes whole if they are smaller in size than a golf ball. In a day or so, the potatoes will form a thick callous over the cuts, which will help prevent rotting.
Nothing wrong with eating a potato that's been around a long time if it's remained fresh. To answer your question, the planted potato decays and is absorbed by the new plant growing from it. New plants start from the root that is on the original potato pc and the flesh just rots into the soil.
You can expect at least five to six new potatoes for each potato you plant. If only every plant multiplied this way! There's something so magical about pulling up a potato plant and seeing so many new potatoes attached to the small one you planted months ago.
When you plant potatoes, avoid planting them near:
You plant potatoes in late winter to spring (February-April) in cooler climates, waiting until after the last frost, and can plant them earlier (March-August) or even year-round in warmer areas, aiming for the cooler months for best growth. The key is planting when the soil is cool (around 45-55°F) but not waterlogged, generally a few weeks before your last expected frost.
Sweet potatoes are so willing to grow that plants accidentally dropped on the ground will take off and grow if the soil they land on is warm and moist.
Absolutely. Look up " sweet potato slips " online for details, but the short and sweet version is to suspend the potato half in water pointy end down. It'll start to sprout and let them go for a few days. Then pull off the sprouts and plant them.
Yes sweet potatoes are SO easy to grow! You can either start off with a sweet potato that has sprouted, or plant the vine with roots of an existing plant. Being a root crop, they like a deep rich soil, about 15-20cm deep to spread out their roots. The better the soil, the more roots you'll harvest!
