On many occasions, I’ve been tempted to grow my own potatoes. They’re fairly low maintenance, can be grown in a pot or in the ground, last a fairly long time if stored properly, and can be very nutritious (high in potassium and vitamin C). Here’s more incentive: according to this article, you can grow 100 pounds of potatoes in 4 sq. feet.
The Hack: Add another side and soil (or hay/grass clippings) every time the plant grows one ft. Makes it easier in the long run than using a cage. If you’re going to be doing this on a regular basis, making a “Lincoln Log” style bin would be easier, since you wouldn’t need to use the screws, just stack and fill!
