My husband used our cedar trees to make boards for my potato tower. Here it is with its first layer and some chicken pecked straw as cover. We selected red pontiac potatoes for our first box. They are one of the varieties recommended for the towers.
As the vines begin to grow you add another board on each side and fill with more dirt, compost or straw leaving some of the vine exposed. Keep going until the tower is filled.
Once the bottom layer of potatoes have matured to the size you want, remove the bottom layer of boards and scrape out the potatoes. Push the dirt back in place and replace all the boards.
Make sure you select a variety that will set potatoes as far up the vine as possible.
We put this box next to our little side garden so we can watch it. We may try another variety next to it and perhaps other methods up in the big side garden.

Our neighbor gave him a hand, or two!
We are getting some cooler weather this week, hoping we don't get a freeze. We have grapes on the vine due to the early spring, small peaches plus a couple of potato eyes planted in this box. Most everything else is a cold weather plant plus perennials. We'll keep our fingers crossed!
