Ornamenthal Sweet Potato Vines

What do type of fertlizer do you use on ornamenthal sweet potato vines?

Hate to admit this, but we use the same fertilizer on the Ornamental Sweet Potatoes that we use on everything else here. I think it's called "Low Country 10-10-10 Plus". Seems to work, because we keep having to hack them back every week or two...and they come back year after year.

Thank you for the informatgion. The ones in the ground really go to town, the plants in the pot just sort of sit there
