we got a bunch of tires to plant potatoes in last year, but never got around to it. this year i put them out front, filled them with potting soil, and went crazy at the store, getting everything that struck my fancy. all the plants are doing super good. i think the black tires soak up the heat and keep it warm, and the curved tops help keep the moisture in, so the plants really like it. now i'm looking for more tires...
