A Sure Fire Way To Grow 100 Pounds of Potatoes in A 4 Square Feet Area

  • Build your own potato growing box. Greg Holdsworth over at vegetablegardener.com shares how to build your own 4 square potato growing box. To start you will need:

    6 pieces of 2×6″ boards of 8 ft long;

    one piece of 2×2″ board of 12 ft long;

    96 pieces of 2 and 1/2″ wood screws;

    Don't you mean potato grow box? Nope, that's not a typo. As the areas of my garden devoted to perennials has gradually increased, the need to use the remaining space more efficiently has become more important. Using trellises and other vertical growing methods greatly help in this challenge.

    Though my first attempts at growing potatoes the last couple of years has been successful, it took up a fair portion of the raised bed(s) they were growing in. This year, I am again doing another “first” – growing potatoes vertically. The “potato box” or “spud box” has become an effective method to produce a large quantity of potatoes in a small space. The idea is ingenious – forcing the potato plant to “stretch” upward as it grows allows more area of the plant to produce potatoes.

    The potato “growing” box is just that – a series of frames that stack, or grow, as the potato plant grows. I like to look at the frames as resembling the floors of a building. In this project, our potato “building” will be six stories tall.

    The list of things you'll need:

    1. Six – 2″ x 6″ x 8′ untreated wood boards

    2. Two – 2″ x 2″ x 6′ wood studs (or one 12′ long stud)
    Note: I actually went with 2×3's instead of 2×2's because they were straighter. For the purpose of this project, we'll stick with 2×2's to avoid confusion.

    3. About 65 – 2 1/2″ long deck screws (I just got a 1-pound box of them – it's less expensive. You'll have extras, but you'll probably need them later).

    4. Drill and drill bits


    1. Cut the two 2″ x 2″ x 6′ studs into four 33″ pieces (you'll have a few inches left over).

    2. Cut the six 2″ x 2″ x 8′ boards into 12 lengths of 21″, and 12 lengths of 24″.
