Uses - Harvest the roots after the first frosts to make your own fiery horseradish sauce. It can also be used in stews, sauces and dressings. The leaves, which are quite bitter, can be used as a cooked/wilted vegetable green. There are also a number of medicinal uses associated with horseradish.
Growing conditions - Horseradish should be planted in full sun or partial shade. It doesn't like to dry out before it get properly established, but once established it shouldn't require any watering unless it has been exceptionally dry. Add a layer of mulch each spring to retain moisture. Plant in a deep fertile soil to get the best roots.
