I found a disk shaped item at michaels , it looks as though it is for fake flowers in flower pots, it is made to look like grass growth on the top of the soil in a flower pot, I guess you would simply buy the correct size for your pot and just place it over the fake soil then poke your fake flowers through it. they come in a couple fo different sizes. I bought it for 2 or 3 bucks. I cut it up with a sizzor and shreaded off the cotton that it is stuffed with and glued to my foreground with white glue. It looks great as it has shape to it and different shades. You could find it in the fake flower section right next to their liechen. I will take some pictures of the area I used it in and post them. Makes a great grassy siding area, tress could be added o spruce it up.
