Hello, my yard is mostly brick. However we have a build up area with a large tree in the middle of it. The area is dirt, nothing can be planted there. The tree has roots that stick up through the dirt. We have only lived here a little over a year and are now wondering what we can do about this area. I was looking at patio stones the other day in the home improvement store but am wondering if this would be a good idea? Thanks in advance for any opinions.
