This 4 square foot box is capable of growing up to 100 pounds of potatoes! Pretty amazing isn’t it?—
Vertical gardens are the perfect solution when you have limited space. However, you do not have to have a problem with space to take advantage of the ability to grow a lot of food in a very small area. This 4 square foot box is capable of growing 100 pounds of potatoes!
1. Six 2″ x 6″ boards – 8 ft. long – (Cut these into 33″ pieces (about 16) and use for side slabs)
2. One 2″ x 2″ board – 12 ft. long 2″x2″x12′ — cut 12
3. 2.5″ wood screws — 96 of them
• Cut the 2″ x 2″ x 12ft. board into four 33″ long pieces.
• Take the 2″x 6″x 8ft. boards and cut them into 12 pieces 21″ long and 12 pieces 24″ long. Drill screw holes in these and attach along the bottom row all the way around (4) of the 2″x2″x33″.
• Place this part of the vertical garden over the soil, fill with mulch and plant potatoes about 4 inches deep.
• Remember that each layer you plant must have its sides boarded up.
Grow and Harvest
• Water really well – potatoes like water! Also, make sure the soil on the bottom of the planter is wet as well. Some people, dig a kind of ‘mote’ around the base of the potato box and water from the top and from the bottom. Allow them to dry completely between watering.
• When the vines reach at least 12″ above the soil, it’s time to add another set of boards and fill the space with dirt. Make sure you don’t cover more than a third of the plant. Do the same for each layer until you finish the box.
• To harvest your potatoes, take the screws out from the bottom board. With your hands reach in the box and grab your potatoes. Replace boards and soil and the layer is good to go again.
• After they grow awhile longer, remove the second board and have yourself a handful of potatoes.
• 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.
