One pound of sweet potatos grown in black planters. I started with 4 plants. What was put out in the ground died so I don't have a comparison of whether the planters worked better or not. I also don't have a price yet on what local sweet potatoes will be selling for, so no figures on cost effectiveness. What I do know is that they were so good roasted with some olive oil and salt for dinner.
There were quite a few little fingers of sweet potato that I think would have grown larger if there had been more heat this summer.
(There is a little carrot tucked in there too. )
Took some cuttings before I pulled the plants. Not quite sure what I'll do with them if they root. If I can keep them alive until next spring I could plant them.
