Dew retting process

With dew or field retting, plant stems are cut or puUed up and left in the field for 4—5 weeks to allow dew and rainfall to affect the process under suitable climate conditions including air, humidity and ambient temperature. The process is monitored to avoid underretting or overretting to ensure that the bast fibres separate firom the inner core without much deterioration in quafity. The dew retting process is weather dependent and time-consuming, so it is usually replaced by other methods.
