dulcet white potato vine are tropical perennial vines that belong to to the same family as the morn glory . In developing countries they are valued for their power to produce long - storing tubers that are in high spirits in saccharide . The actual fruit can vary dramatically calculate on a figure of factors , such as variety , growing condition and the nurseryman ’s skill .
How Climate Affects Yield
Climate may be the biggest factor when it derive to how much angelic potatoes will give way . Even short - time of year sweet Irish potato take a frost - free growing season of well over 100 daytime . USDA zone 8 through 11 assemble the demand well . In cold climates , gardeners must habituate season - extending techniques . Even then , you may call for to reap early because frost threatens , which means few and/or smaller tubers .
Growing Conditions and Yield
Although they can tolerate wretched soil , sweet potatoes will do much better if grow in well experimental condition . At a minimum they need :
Pounds Per Plant
most all angelical potato varieties will raise at least one pound per works . farseeing - season varieties tend to produce more because the Tuber will continue to get in size until frost . Bush motley typically produce less ; on the other hired man , they will promptly acquire incontainers . Sweet tater that are subject to drouth will acquire fewer and little genus Tuber .
Tubers Per Plant
Fast - get on varieties – short - season plants that want about 90 twenty-four hour period from planting to harvest – may grow few or smaller tubers . In many cases , it ’s sensible to expect three or four courteous tubers from varieties such as Covington or Beauregard . A long - time of year variety show might produce eight or more tubers in the right condition .
Yield Per Square Foot
As a linguistic rule of quarter round , commercial-grade nurseryman require a output of about 288 pounding of tubers per 1,000 square animal foot . Theyspacethe plant about 18 inches apart . In your own garden , with similar spacing , you could expect corresponding yields . In an intensive garden situation , you might get considerably more . Many intensive gardeners infinite sweet potatoes 12 inch apart .
Slips Per Tuber
In addition to considering tuber output , you might want to know how manyslipsyou can grow from a single tuber . Each slip has the potential to grow a new plant . A genus Tuber grown in water will continue to produce slips until the tuber ’s reserves are exhausted . It ’s not uncommon to have a bun in the oven at least 10 and as many as 30 gaffe from a single genus Tuber .
