Horseradish.–Widely used as an appetizer, Horseradish is a kitchen-garden vegetable, that is usually planted in some out-of-the-way spot and a piece of the root dug as often as needed, the fragments of roots being left in the soil to grow for further use. This method results in having nothing but tough, stringy roots, very unlike the product of a properly planted and well-cared-for bed. A good horseradish root should be straight and shapely.
The best horseradish is secured from sets planted in the spring at the time of setting early cabbage, and dug as late the same fall as the weather will permit. It becomes, therefore, an annual crop. The roots for planting are small pieces, from 4 to 6 inches long, obtained when trimming the roots dug in the fall. These pieces may be packed in sand and stored until wanted the following spring.
In planting, the roots should be set with the upper end 3 inches below the surface of the ground, using a dibber or sharp-pointed stick in making the holes. The crop may be planted between rows of early-sown beets, lettuce, or other crop, and given full possession of the ground when these crops are harvested. When the ground is inclined to be stiff or the subsoil is near the surface, the roots may be set in a slanting position. In fact, many gardeners practice this method of planting, thinking that the roots make a better growth and are more uniform in size.
