Dew retting or ground retting involves spreading out the dried straw on a grassy lawn or field for several weeks, and allowing fungi to consume the pectins. America is no longer producing much in the way of textiles, especially from hemp, at least not yet: Most hemp fiber is grown and processed in China, supported by small pockets in other parts of Asia and Eastern Europe.
