NEVER USE TIRES IN YOUR GARDEN
Q: I am interested in tire gardening but I have heard comments that indicate that it would be almost toxic suicide. L.R., North Carolina
A: Tires do contain some toxic materials but I don't know how much they release to contaminate soil and plant roots. I would suggest the use of cinder blocks. They can be stacked into various shapes and changed if needed. I use them with the holes pointing up and fill them with lava sand. Concrete wall systems and natural stone are even better.
