Has anyone seen this stuff before? I saw a bag of this "landscape mulch" that was actually colored rubber shredded to look like bark. I'm guessing it's recycled shoes and stuff like those asphalt alternatives that are becoming popular. I was just curious to know if anyone had tried using this stuff in cultivation - possibly in the place of orchid bark or gravel? ...I don't know. It was squishy and warm from sitting in the sun when I noticed it; I felt the stuff through the bag but it was weird and I couldn't tell if it would be very useful or not.
