My local rock yard has these rocks that I'm considering for edging my pond. I'm concerned that the gray concrete will look kind of funky around the tan stones. It seems like I have read on here that the concrete blends in more after everything is weathered. How long does it take? Would gray concrete ever look ok with these stones? Quikrete makes a buff dye that looks like it would be a pretty good match. Anyone have experience with these
dyes?
