Horseradish is being hailed as the 2011 Herb of the Year

Horseradish leaves - Armoracia rusticanaArmoracia rusticana Horseradish, a member of the mustard family, is best known today as a condiment, but it originated in antiquity and was recorded as early as 1500 BC. Horseradish became known in Medieval Northeastern Europe and western Asia as a valued medicinal herb used as a mild antibiotic and diuretic.

Horseradish was more commonly used medicinally than as a condiment for centuries, largely because of its powerful flavor. It wasn’t until the 1600s in England that the ground root of the horseradish, mixed with vinegar, was accepted in cooking; even then, it was considered too harsh for general use.

It did eventually catch on and become a staple, however, in the U.S. The use of horseradish sauce as a condiment is associated with roast beef. It is also widely used in Russian cooking and in the Middle East as a sliced and pickled snack. Horseradish leaves can be added to salads.

growing horseradish - horseradish cultivation

Horseradish can be grown as an annual, which is the preference when horseradish is to be used as a culinary herb or medicinal herb.

Knowing when and how to harvest horseradish is simple to learn.

After the horseradish leaves begin to brown and die back following the first frost in the autumn, the horseradish root can be dug and divided.

When the main horseradish root is harvested, one or more of the smaller offshoots of the main root should be replanted to produce next year's crop.

Older plants should be dug and discarded or the roots divided to start new horseradish plants.

Horseradish left undisturbed in the garden spreads via underground shoots and can become invasive.  Older horseradish root left in the ground will become woody, after which they are no longer useful as a culinary herb.
