How to Grow 100 Pounds of Potatoes in 4 Square Feet

The more GMO and non organic food we get in our children’s plate, the more we will want to grow our own organic food. Di you know that the U.S. Department of Agriculture approved a few new genetically modified potato varieties for farmers to grow commercially last year. An of course you will all want your own, home grown and cheap potato.

Well, here is instructions on how to do it. You can grow 100 pounds of potatoes in 4 sq. feet.


This article from the Seattle Times, says potatoes planted inside a box with this method can grow up to 100 pounds of potatoes in just 4 square feet. All that is required:

  • Lumber
  • Seed potatoes
  • Soil
  • Careful attention to watering

This is the sketch for building a 100 lbs potato growing box The Times showed:


You will need to plant them as early as April or as late as August 1, with an approximated 3 month till harvest turnaround time.

These are the directions:

  • Cut apart larger seed potatoes, making sure there are at least two eyes in each piece you plant.
  • Dust the cut pieces with fir dust, which seals the open ends from bacteria.
  • Fertilize with 10-20-20 fertilizer at planting and a couple of times during the season.
  • Water so that the plants are kept at an even level of moisture.
  • Don’t plant in the same area in consecutive years or use the same soil to fill your potato box, as potatoes can attract various diseases.

“To save space, Lutovsky recommends building a box and planting inside it, adding sides to the box as the plant grows and filling the new space with mulch or soil. When the plant blossoms, it starts setting potatoes in this added soil. Soon after that, you can start removing the bottom boards from your box and “robbing” the plant, reaching in carefully and pulling out new potatoes.”
