26+ Growing Potatoes In Tires. Old tires are one of the best. George elliott, owner of first choice yard design in redding, california, demonstrates the technique for growing potatoes in stacked tires.
If you have room for a car tire placed flat on the ground, you can grow four to five potato plants with lots of potatoes on them. This idea of using old tires as pots is very resourceful. Growing potatoes in containers can save space and simplify the process.
About a week before planting, place seed potatoes in a warm spot.
The system goes, you plant your potatoes in a tire filled with soil, when the potato grows up you add another tire with more soil (much as you would add soil to a potato trench), and continue this for three or four tires. Simply find an ideal location to begin growing your first harvest. Prepare the tires by taking them off the car and rolling them around to the garden. As the plant grows you add another tire to the stack, causing the growth of more potatoes.
