Only people who have grown horseradish in their garden know how truly pungent and delicious horseradish can be. Growing horseradish in your garden is easy. Just follow these tips on how to grow horseradish and you will be harvesting horseradish for many years to come.

Planting Horseradish

A horseradish plant (Amoracia rusticana) is typically grown from a root cutting. These can be ordered from a reputable nursery or you may be able to find someone locally who is raising horseradish and would be willing to share some of their horseradish plant with you. As soon as you get your root cutting in early spring, plant it in the ground. Dig a hole that is deep enough to stand the root up. While holding the root upright in the hole, back fill the hole until all but the crown of the root is covered. Once the root is planted, water your horseradish thoroughly then leave it alone. When raising horseradish you don't need to fertilize or fuss over the plant.

Containing a Horseradish Plant

Once your horseradish plant becomes established, it will be yours for life. One thing to keep in mind is that when growing horseradish, you need to either give it lots of room or provide firm boundaries. Horseradish will spread vigorously if steps are not taken to contain it. If you do not wish for your horseradish plant to take over your garden either grow it in a deep container or bury a plastic tub around it in the ground. This will keep the growing horseradish plant in check.

Harvesting Horseradish

There are two schools of thought when it comes to harvesting horseradish. One says that you should be harvesting horseradish in the fall, right after the first frost. The other says that you should be harvesting horseradish in early spring, when the horseradish plant needs to be divided anyway. Which of these is best is up to you. Both are acceptable. Dig down around the horseradish plant as far as you possibly can and then with your spade, gently lift the horseradish root out of the ground. Break off some of the roots and replant them in the ground. The rest of the horseradish root can be processed into ground horseradish. Raising horseradish is very easy to do. There is very little to know about how to grow horseradish. It actually does best if you plant it and then ignore it. Growing horseradish can be rewarding and tasty.
