Looking for some input on rubber mulch. I have read a few threads on here regarding it and found some pro's and con's about it. Currently in this bed are 3-4 inch river rock and the homeowner said they have been having problems with the dogs going to the bathroom on it and its hard to clean up. Also weeds and crickets hiding in the rocks. So one of my ideas was rubber mulch since there are only flower pots around the area and not any plants actually in the ground. Besides for rubber mulch I was thinking pea gravel, regular mulch (customer did want a very low maintenance solution and the area is not very accessible.) and some sort of ground cover. This area is around the perimeter of a very very small patio. If anyone has any input to rubber mulch or any other options I would gladly appreciate the input.
