Here's an interesting one - a product to stop weeds, made from human hair.|
You can buy circular mats of hair, measuring 6 to 14 inches, that you place around plant stems. Or you can buy the mats as a roll. The hair crowds out weeds, conserves water, and supplies nitrogen and micronutrients. Plant pathologists at the University of Florida have found the mats eliminate weeds better than leading herbicides.I really can't add much - it's just too weird.
The hair mats are made in China. But not because of cheap labor. In China, hair is a commodity, used in wigs and even as an additive in food. While American barbers sweep hair into the trash, Chinese haircutters sell their trimmings to brokers. Blair Blacker says Chinese hair is also more nutrient rich because it's not as treated as Western hair. That means Smart Grow hair mats, which have the consistency of a soft brillo pad, come in just one color: black.
