- Step 3 : Pre-drill the screw holes in the 2-by-6 boards and attach the bottom row on the 2-by-2s
- Step 4 : Place over prepared soil and fill with soft soil or mulch, planting potatoes four inches deep.
- Step 5 : When the vines are about 12 inches above the soil, add another board and fill with dirt; being careful not to cover more then one-third of the plant Repeat this until the box is completed.
- Step 6 : To harvest your potatoes; remove the screws from the bottom board and carefully reach in for the potatoes. Replace the soil and boards. Next time you need potatoes, remove the second board and "rob" spuds from that level.
