When my boys were little we’d grow potatoes in stacks of old tires. (’Farmer Grandpa’ always had old tires!) One tire, fill with dirt and 6 potatoes - let it grow, add another tire and more dirt, throw in a few more potatoes, and let it grow.
We’d get 6-8 tires stacked up, and when they were ready to harvest, we’d push the stack over and have at it. Nice, clean potatoes...though you probably don’t want the stack-o-tires right on your front lawn, LOL!
(We kept ours behind the barn in a sunny spot, near the compost pile.)
Yeh I think the stack of tires is a great idea if you are out in the country. When we move permanently I want to try it. Right now I usually do five 5 gallon buckets with baby reds and some Yukon gold. Here you canto a spring and a fall crop. So far this year we have not even had a hard freeze. 2 of our chickens molted again about 6 weeks ago. Crazy weather this year.
