My friend John's recent post regarding Wal-Mart's attempt at going green also included a brief about rubber mulch... Interesting reading.
My follow up is in regards to the mold and fungus associated with rubber mulch and my own experiences with it.
I want to add that I think it's great that Wal-Mart is at least trying to do it's part by adding 'green' products to it's inventory. If you think about it, a large percentage of American's shop at Wal-Mart, so now, a larger percentage of American's will be buying more 'Green' products.
