Sötpotatis kan hålla länge, över vintern under bra förhållanden.
Jo, i kruka är det lätt, det blir ju en tjusig inneväxt som man kan ta blad av om man blir hungrig.
Urs, jag borde leta upp ngn bok som jag hade om detta.
Här är saker jag sparat om sötpotatis, vet inte var jag hittade det längre.
Sötpotatisen är inte alls släkt med vanlig potatis utan hör till familjen vindeväxter. I Sverige finns bland annat åkervinda och snårvinda. Sötpotatisen härstammar dock från Centralamerika. I Sydöstasien är det vanligt att man använder blad och skott som grönsaker och de har faktiskt högre halt vitamin A och C än rötterna, så du kan lugnt ha dem i sallad eller woka dem. Sötpotatisen är solälskande och vill ha både varma dagar och nätter. Torr väderlek gynnar sötpotatisbildningen, men samtidigt krävs vatten och syre för att den skall svälla. Jorden bör därför vara lucker och bäddodling är att föredra. Det finns en lång rad olika sötpotatissorter med olika inre färg, skalfärg, storlek och form vilket gör det svårt att säga hur just din sötpotatis vill växa. Prova dig fram, sätt dem på olika djup. Vill du bara ha bladen går det ju uppenbarligen bra att odla med halva sötpotatisen ovan jord, men vill du få nya knölar bör den vara helt jordtäckt.
Sweet potatoes, which are related to the morning glory, grow on trailing vines that quickly cover the soil, rooting at the nodes along the way. "Bush" varieties with shorter vines are available for situations where space may be limited.
Though orange-fleshed varieties are most common today, white or very light yellow-fleshed types were once considered the finest types for sophisticated people. Some white-fleshed types are still available, though they may be hard to find outside the Deep South.
For their ornamental value, sweet potatoes are often grown as ground cover or in hanging baskets, in planters and even in bottles of water in the kitchen. Cut-leaf types exist that are particularly attractive. The sweet potato is rich in vitamin A. It is not related to the yam, though in the marketplace the two names are often used interchangeably. The true yam, Dioscorea sp., is an entirely separate species that grows only in the tropics.
Sweet potatoes are started from plants called "slips." Transplant the slips as soon as the soil warms up after the last frost to allow the maximal warm-weather growing period. Always buy plants grown from certified disease-free roots. To grow your own plants, place several sweet potato roots about one inch apart in a hotbed and cover with two inches of sand or light soil. Add another one inch of sand when the shoots begin to appear. Keep the soil in the bed moist throughout the sprouting period, but never allow it to become waterlogged. Keep soil temperature between 70° and 80°F. Plants are ready to pull in about 6 weeks (when they are rooted and 6 to 8 inches tall). You can allow roots to continue possibly producing additional flushes of plants if more are desired. The sprouts (slips) are planted directly in the garden from the sprout bed.
Set the plants 12 to 18 inches apart, preferably on a wide, raised ridge about 8 inches high. A ridge not only dries better in the spring but also warms earlier than an unridged area. Black plastic mulch can be a good way to speed early season growth by capturing and storing more of the sun’s heat in the soil under the plastic cover. Because the vines of spreading varieties need a great deal of space, allow at least 3 to 4 feet between rows
After early cultivation (which is not necessary with black plastic), sweet potatoes need minimal care to keep down weeds. Once the vines spread to cover the ground, little weeding is required. Irrigate if an extended drought occurs. Do not water during the last 3 to 4 weeks before harvest to protect the developing roots.
Early roots may be "robbed," starting in late summer, by digging into the side of the ridge and carefully removing some developing roots while leaving the plant in place. Dig the main crop of sweet potatoes around the time of the first frost in the fall. Use a spading fork or stout shovel and be careful not to bruise, cut or otherwise damage the roots. Dig below the level of the ridge and gradually move closer toward the plants, removing soil until the fat roots are exposed. Carefully dig under these roots to gauge the depth to dig as you go down the row.
Proper curing can be a problem in the cool fall season. Ideally, the roots should be allowed to dry on the ground for 2 to 3 hours, then placed in a warm room for curing (85°F and 85 percent humidity (if possible) for 10 to 14 days and then stored in a cool (55°F) location. Sweet potatoes should be handled as little as possible to avoid scuffing and bruising. In case of frost, cut the vines from the roots immediately to prevent decay spreading from the vines to the roots and dig sweet potatoes as soon as possible. Cold soil temperatures quickly lessen the roots’ ability to keep in storage. Do not allow roots drying in the garden to be frosted because they are quickly ruined. For best quality, use the potatoes as soon as possible after they have been stored.
To prevent diseases, plant varieties with multiple resistance, use "certified" plants and rotate sweet potatoes’ location in the garden.
At certain sites, mice may become a problem by burrowing into the mound and eating the tasty, nutritious roots before harvest can commence. Check for evidence of mouse infestation regularly and apply appropriate control measures as needed.
Storage:
Use care in digging potatoes, being careful not to cut or bruise them. Then put them in a storage house with a temperature of 85°F so they may ''cure'' or dry out for 8 to 10 days. Then the storage temperature may be dropped to 50 or 60°F. Avoid ''chilling''. After storage do not handle potatoes until they are used. Excessive handling will cause the potato to rot in a very short while.
Successful Sweet Potato growing is very interesting. Some local farmers grow 300 bushels per acre, others only 100. The good farmers do not leave production to chance. They work, hoe, and cultivate their crops. After visiting fields of potatoes in Texas, Mississippi, Alabama, Georgia, and reading about production in other states it is hard to describe the ideal way to grow sweet potatoes in general. Most farmers follow the above procedure in some manner. We hope the above statements will help you toward a successful Sweet Potato crop this year.
