The traditional approach growing potatoes is to hill them. Essentially, you use a hoe to cover up the potato sprouts as they emerge to get more growth out of them.
In contrast to the above, a growing in containers you grow the potato vertically, above ground. This method has the potential to yield more than an “in ground” method while using less space and reducing the labor required to dig them up.
You can grow potatoes in hay, on compost, directly in the dirt, growing boxes, buckets, chicken whire and any other good sized container.
