Zone 5. This is my second try with sweet potatoes. The first time, I got nada. I had them in my heavy soil garden, thinking they'd like the longer hours of sunlight, but not knowing that they couldn't handle the heavy soil.
I ordered slips and they were late getting here. (My rant about UPS last spring? Yeah, it was about the slips being delayed by about 5 days.) I stuck them in plastic cups of dirt after treating them with rooting compound, just because DH had gotten some to try on tree cuttings.
"Slips" are just stem cuttings. Mine were about 6" long, and they looked SAD by the time UPS deigned to get them to me. I ordered 20, got 24, and 3 of them didn't make it. 1 was the little plant I pulled up a few weeks ago.
When I planted them, they were little twiggy things sticking up in the dirt. Now you can't see the dirt!
I just let the vines wander. This variety is "Orleans," chosen for its short season, since they need a lot of nice warm days. I didn't know that there are varieties that grow more bush-like. This variety is definitely a "vigorous vining type."
A bush habit would be easier to deal with, but the short season has to take precedence. The two tubers I dug were under the original spot where I planted the slip. Some of the vines have rooted along their lenght; I don't know if they make tubers there too?
Might I be buried in a pile of sweet potatoes soon?
