Here’s an interesting, easy way to grow lots of potatoes in 4 square feet – use a box:
The potatoes are planted inside the box, the first row of boards is installed and the dirt or mulch can now be added to cover the seed potatoes. As the plant grows, more boards and dirt will be added.
The boards at the bottom are removed to reach mature potatoes.
We’ve grown potatoes the old fashion way – the kids love to dig them up; but I may try this.
