Jok I think your talking about the sweet potatoes. Well I know jack shit about growing them but have been looking up on line found this site seem quite good, after having them six plugs left on my door step. I've re dug a strip putting in some well rotted dung i've covered in black plastic which i will plant through and cover with a mico mesh on bent weld mesh, and cross my fingers.
