Hello, Iam new to this gardening forum stuff, so bare with me. I have recently found my self taking care of the yards by myself with very little real knowledge about what Iam doing, so I will probably have many questions in the future as I really enjoy it.my first question is: I have made a 20'by 20' flagstone rock area and want to put decorative pebbles instead of a groundcover(because of the dogs) .does any one know what I can use to seal them and keep them from scattering around? thanks katt
