I am looking for DuPont Landscape MAX Maximum Weed Defense Fabric. This is guaranteed for 20 years. The company says that Lowes has it, but mine no longer stocks it. This is in my experience the ONLY weed block fabric that really works. The fabric is tan on the top and a bright white on the bottom. It comes in 50x3 ft rolls. If anyone knows a source, I'd be very happy to hear about it.
