I had something similar years ago from Gardener's Supply. They were black and they had four holes to poke cages through. I guess they probably lasted for 3 seasons or so before disintegrating. They were ok, but now I just use black plastic with some mulch around the planting holes and it's weed-free all season long. When I don't have enough plastic, I lay down 2 layers of newspaper and cover it with pond weed or grass clippings. However, I think the plastic does a better job of keeping the moisture in.
I bought some red plastic on sale at the end of last season. If it's too thin, I will put newspaper under it, as that keeps the weeds from poking through. Maybe I can get a fourth season out of my black plastic as well..... We shall see.
