After harvest, the sweet potatoes should be cured. This involves placing the potatoes in a warm (85 degrees) humid (90 percent) environment for about 4 to 6 days to increase sugar content, heal nicks and bruises incurred during harvest, and increase flesh color.
How do you treat fresh dug sweet potatoes?
In order to cure for long-term storage, sweet potatoes need high humidity and heat above 80 or 85 degrees for one to two weeks. To achieve these conditions, place sweet potatoes in a single layer in a plastic grocery bag. Tie the bag closed but also cut holes in the bag for ventilation.
Can you eat sweet potatoes right after you dig them?
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.
How do you cure potatoes after harvesting?
Damaged potatoes will rot during storage and should be used as soon as possible. After harvesting, potatoes must be cured. Let them sit in temperatures of 45 to 60 degrees Fahrenheit for about two weeks. This will give the skins time to harden and minor injuries to seal.
How long can sweet potatoes stay in the ground?
You can expect sweet potatoes to retain their quality for six to 10 months, but some cultivars may begin sprouting after six months. They will taste better if you give them a minimum of three weeks in storage to allow their starch to convert to sugar before you eat them.
What happens if you leave sweet potatoes in the ground too long?
Sweet potato roots continue to grow until frost kills the vines. Roots can be left in the ground for a short while; however, a hard frost can cause damage to roots near the surface. Chilling injury also results to roots when soil temperatures drop to 50°F or lower, and this can result in internal decay in storage.
How do you know when sweet potatoes are ready to dig up?
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.
Where can I cure potatoes?
Curing toughens up a potato’s skin and extends its storage life. Cure the tubers by laying them out on newspaper in a well-ventilated place that’s cool (50 to 60 degrees F.) and dark (so they don’t turn green). After about two weeks, the skins will have toughened up.
What happens if you don’t cure potatoes?
Truly new potatoes are sold right after harvest, without any curing. They’re higher in moisture so have a little bit different texture, and their flavor has, to my taste, a slight bitterness that complements the earthy flavor.
What happens if you don’t harvest sweet potatoes?
What Happens If You Don’t Harvest Sweet Potatoes? It is very easy to grow sweet potatoes, but they don’t like cold temperatures. While the roots of sweet potatoes won’t be damaged by the first fall frost, as the soil temperature continues to fall, they won’t survive and will start to rot.
Do sweet potatoes come back every year?
Sweet potato vine is easy to maintain and tolerant of different growing conditions, including heat, humidity and shade. It is a tender perennial grown as an annual in most regions.
How do you prune sweet potato vines?
Cut back vine tips that have exceeded their boundaries. Make cuts roughly 1/4 inch above leaf nodes to encourage new growth. Prune off broken or sickly vines. The more of the vine that is pruned off, the more aggressively the plant will try to regrow.
What to plant After sweet potatoes?
What You Can Plant. You can plant a green manure crop in an area where sweet potatoes have previously grown in the garden.

How do you dry out potatoes?

How long does it take for potatoes to cure?
All potatoes lose moisture in storage, but those with thick skins stay sound longer. Hence the need to separate potatoes by type as they come in from the garden, and give each an appropriate curing period – usually 7 to 10 days.
How do farmers store potatoes?
Potatoes store longest if they are unwashed. After harvesting from the garden, lay them out in a single layer in a dark and airy place to let the soil dry on to the tuber. Lightly brush off excess dirt before you pack them. Pile dry, unwashed potatoes in a clean wooden or waxed cardboard bin.
