Is this perhaps what you were looking for? I saw this HomeTalk member posted about growing potatoes in straw towers here: http://www.hometalk.com/186379/easy-potato-bins
In that posting, she also gives a link to her blog with more detailed info. http://www.sowanddipity.com/you-say-potato/
Try googling "7 different ways to grow potatoes." The article gives lots of detail and the pros and cons of each method. We're trying the straw method this year hoping for great results.
Thanks Angelyn. At this rate I will have to dig a cold store to hold our harvest!
Thank you for all the help- our potato towers are planted. Now for the hard part.... we wait :)
