I planted one trash can of sweet potatoes on the same day that I did the white potatoes. These were plain organic sweet potatoes I bought from Whole Foods. I cut them into pieces and covered them with dirt.
When I posted this the first time I had a commenter say that, unfortunately, you can't grow sweet potatoes using this method. I was ready to throw the dirt out of this can when I spotted this.
Now I suppose it could be some freak weed growing but I'm thinkin that's a sweet potato plant! YAHOO!
There's only one in there, but still, I'm growing sweet potatoes in a garbage can!
