I grow potatoes in 2' x 2' potato towers that are 33" high when full. They are built out of 1x6" cedar fence boards. I have the bottom 2 boards around the base. I put about 3" of compost in the tower, put 10 seed potatoes in and cover with 3" of compost. When the plants get about 9" tall I add about 3" of compost. If I need to I add a board and keep following this process until the tower is full. Red Pontiacs seem to do well and so have yellow finn, cal whites and pioneer russets. They don't all do as well but they all have provided potatoes off of the stems. Yukon Golds haven't done as well but they are also a shorter variety. The picture is red pontiacs.
