early spring growth, was one plant 2 years earlier, is dug 100% every year!
Horseradish leaves can reach 3′ long, shaped like broadswords.
We sell an heirloom variety of horseradish.. The roots, which are the edible part, are very similar to most varieties I’ve seen.
Horseradish is highly adaptive. It will grow in many soil types and climates. Be warned, however, that it is invasive. Plant it too close to your house and it will be popping up in your living room before you know it! The plants are extremely hardy, too. Easily split and transplanted.
horseradish roots
Horseradish is generally harvested in the fall but can be dug any season. By fall, each plant present that spring will have produced at least one other plant through roots. They may forma tight cluster of plants. To harvest, dig up the entire cluster and take the largest, oldest root(s). Replant the smaller roots, amending the soil if you like. The plant is so vigorous, however, that it usually won’t matter if you replant any roots. New plants will soon emerge from root fragments left in the ground. For a new planting it is recommended the first harvest be no sooner than fall of the following year.
Again, caution is warranted when planting horseradish. It is an invasive plant and will spread. Also, it is suspected of being a plant that will kill perennials growing within its root area. For these reasons many people plant it in containers or in areas away from their garden.
