И ты называешь это "organic"?! Ты хорошо изучила теорию вопроса?Навскидку, самый первый вебсайт выдал:Short-term, yes, tire planters are OK, although the soil in black tire planters will probably get hotter than most plants would prefer. Long-term, no, because the tire rubber will slowly biodegrade and release zinc, carcinogenic PAHs (polycyclic  Tire Planteraromatic hydrocarbons) and other toxic compounds into your garden soil.
