Community Garden on reclaimed parking lot
I was going to garden through a local community garden but after I tilled my bed I found a lot of gravel like from a layer of gravvel that is put in under a blacktop. I also found some pieces of asphalt, or blacktop. The garden is on land that was once a part of a parking lot. Now it is grass. I do not think I want to chance that it is safe to grow food in. There are contaminants in blacktop Right!
