Several gardening trends are colliding. Lots of new gardeners want to grow vegetables and raised beds are very popular. Combine that with a desire to be green and reuse material and tire gardens seem to be a good option. These are gardens made with old discarded tires.
Tires have another big advantage. They accumulate heat which potatoes and tomatoes just love, especially in colder climates.
But are these tires safe? Do they leach toxic material that will get into the food and contaminate it? There are lots of opinions on this, but very little in the way of a scientific review. Time to change that.
