what can I put between flagstone to keep weeds from growing?
I have a flagstone patio and the stones are just laid on the dirt. They seem to be setting just fine but I want to keep the weeds from growing in the dirt between the stones. I would like to keep the natural look and do not want to mess with planting things I will need to water. What can I use to fill in the area between the stones to keep weeds from growing?
