I once planted a sweet potato that had some healthy-looking shoots on it.
I just planted the whole thing as is. It grew vigorously, spreading to
occupy a large area with lush green foliage. In late summer I decided I'd
dig just a corner of it to see how big the potatoes underneath were. So
I started to dig, and dug and dug, until I eventually had the whole plant
up. All I harvested was the same old potato I'd planted! There wasn't a
single new one to be found. So sweet potatoes certainly have different
requirements from the South American spud.

I don't know what sort of sweet potato you're referring to. But here
in New Zealand the kumera (purple skinned ) is planted in a J shape.
That is, you bend the roots when you plant them. We can buy the
seedlings which just seem to have a little purple root with hairs off
it and a few leaves. They like to have a hard pan underneath some
nice soil is what I've read. So some people put a sheet of iron
underneath the soil to encourage the roots and tubers to stay high.
Then you have to heap it I think but look under 'kumera growing' and
see what you find in Google.
