Weese mentioned planting potatoes in her yard the other day. Many people don’t know this little potato trick, but you can harvest a field of potatoes from a three-foot by three-foot box if you are limited for space.
What I’ve done in the past was to construct a wooden box where I could add or remove the boards on the side. I’d plant the potato starts in some soil on the bottom and as the greenery rose above the soil I would cover most of it with more soil. By the end of the summer the box will be filled with dirt and the potato start would still be at the bottom and tubers will have formed and grown all the way up the stem that I continually buried.
You can do this in just about any large container as long as it doesn't hold water in the bottom.
When the foliage at the top finally dies in the autumn at the top of the box it is time to remove the boards and shovel away the soil. You will find you will have close to 100 pounds of potatoes all grown in a three foot cube.
This method is much easier than a potato field because to grow potatoes properly in the ground you need to dig a deep rut and hill the soil constantly. It’s just easier to control a big cube than it is to manage a field. It takes less space and less water. It’s not too late to try it this year. Have fun!
