Put a handful of compost in the bottom and cover it with 2 inches of soil. Push each root piece into the soil at an angle rather than straight up and down. This will help the roots that grow along the length of each cutting to grow straight down without getting tangled up. The top of the root cutting should be 2 inches below the soil. If you take cuttings from a freind's garden, mark your roots in the same way.
Harvesting Dig up a piece of the root, wash, and scrape it under water to prevent eye irritation.
