I am posting a link to a post from the 2009 Gardening thread on growing potatoes in a container. The original poster is no longer on FR. He was our expert on growing potatoes and this post is a step by step guide on how he grew his. Hope this is a help.

Thank you, Thank you Red. I’d pulled that down when he posted that information. I’ve pulled it down again, and put it in my gardening book.
