Last year, around this time, I got into urban gardening. Inspired by my sister, I built a square foot box for spring planting and had a blast learning about growing your own garden. I didn't have the most prolific crop, but I did have a lot of fun doing it. While doing some research I ran across the idea of a potato box. I was attempting to grow potatoes in my square foot box and it was not working out. I was not familiar with how potatoes grow, but apparently if you grow them vertically and continue to cover up the vines as they grow (leaving a few inches of uncovered vine up top of course) they will continue to root and put out potatoes. I found this website that tells you how to build a "Potato Condo," which supposedly grows 100 lbs of potatoes in 4 sq feet. My sister and I talked about this idea right after I found it and she was really interested in doing it, so I built her a box for Christmas. It turned out pretty great. Here is a picture of the final product...
The idea is that you start with your box set-up with 2-3 boards around the base. I decided to build 1 side that wouldn't be removed all the way up. You fill the box with soil and plant your potatoes in the base of the box. Once they grow up high enough, you add another layer of wood (which is already cut and pre-drilled) and then more dirt. You continue doing this until you reach the top. You will need to be familiar with planting and harvest times. When the potatoes on the bottom have been maturing for long enough, you take off the second layer of boards from the bottom and harvest the mature potatoes. You continue to work your way up the layers as the potatoes mature. Supposedly by the end of this, you will have yourself 100 lbs. of potatoes. I built myself one too, so I suppose we will see very soon if it works! If it works, I am going to need a lot more recipes that use potatoes.
