Burdock

Growing

As a biennial, burdock follows a two-year life cycle where the edible root develops during the first year. You should sow seeds in well-draining, nitrogen-rich soil, as this plant thrives in fertile environments. Because the roots can become quite large and woody, ensure your garden bed is loose and deep enough to allow for unobstructed downward growth. While the plant is highly adaptable to various light levels, it performs best in full to partial sun.

When the time comes to harvest, you must pick the roots while they are still tender and ready for use, as they do not continue to ripen once removed from the earth. To prevent the root from turning unpleasantly dark or developing a harsh, muddy flavor, be mindful of the tannins that react with iron. For long-term use, you can store unwashed roots in a cool, dark cellar or the refrigerator. If you plan to preserve them for the winter, blanching the roots before freezing is a highly recommended technique to maintain quality.
