If you are limited in space, planting potatoes in containers might be the way to go. With the method shown in the video below, you use organic potting soil, cow manure, and peat moss in three equal parts. You will only fill up the container one third of the way. When you see that the plant are stating to come out of the soil then you will add more of your soil mixture. You will do this one more time and at the end you will add mulch to help keep moisture in and light out.
Here is a great step by step video called “How to Grow Potatoes in Containers” from Hollis & Nancy’s Homestead.
