Last year I grew sweet potatoes from slips and they just grew in a clump. This year I grew them from slips and they are running all over the place. Will sweet potatoes grow where ever the vine goes or just in the center of the original plant?
They can grow a potato from any place that puts down a root with enough time and nutrients. The problem is the amount of time and energy available .
Generally it is recommended to pull up runners to stop them from forming potatoes except at the center.
That way you concentrate the roots where the original plant is and get a potato big enough to be useful.. Otherwise you end up with a lot of small potatoes.
I got them in pretty late. I'll cut them back. Thanks!
Don't cut back, just don't let the vines root in. Usually on a hot sandy surface that isn't a problem, but check and see if the vines are shooting out rootlets and if so just detach the roots from the ground.
let em grow. Sweet potato greens are delicious. Just snip the leaves and either steam or boil them til tender. Plus ,the smaller potatoes are sweeter. Boil a pot full of them with skins on til fork tender, drain, pinch the skins off, add some butter and yummmm
There are short-vine sweets available, (dwarf)...the potatoes are normal-size....., they are better for a small yard...sally
