How to grow horseradish from store-bought roots?

In this brief guide, we will answer the question “How to grow horseradish from store-bought roots?” with an in-depth analysis of how to harvest horseradish. Moreover, we will also discuss the nutritional value of horseradish. 

Horseradish is usually started from the root itself, unlike most vegetables for which seeds can simply be found in a catalog. Horseradish plants and roots can be difficult to come by and are often only available at specialty nurseries. You might be able to receive a root from a buddy who is growing horseradish, but what if you don’t know anyone who is growing horseradish?

Horseradish roots are now available in many grocery stores’ produce departments. If you can’t find them at a regular grocer, look for specialist grocers that specialize in rare or organic produce.

How to grow horseradish from store-bought roots?

To grow horseradish from roots follow the given guide:

  • Purchase a horseradish root from a local supermarket.
  • In a 5-gallon container, place the root at a slight angle in the soil. (A 5-gallon bucket will suffice. Horseradish spreads quickly, so unless you want it to take over your garden, you should grow it in a container. While containers larger than 5 gallons may work, you should not go any smaller than that because you want enough room for the roots to grow. After all, the main crop is the roots.)
  • Set the root outside after covering it with more dirt. (Place the container outside after making sure the root is completely covered. Even before the last frost, roots can be planted outside in early spring. Planting in the spring allows the plant to grow its roots as much as possible. Rain should be enough water to get the plant to grow in most regions.)
  • Watch it grow.

What is horseradish?

Horseradish is thought to have come from Eastern Europe. Along with mustard, wasabi, cabbage, broccoli, and kale, it’s a cruciferous vegetable. Its strong flavor and odor give any dish a spicy boost. To use as a condiment, the root is grated and preserved in vinegar, salt, and sugar. Prepared horseradish is what it’s called. Several compounds found in this root may be beneficial to health, including antibacterial and anticancer properties.

How do you get horseradish root ready to plant?

To use in the kitchen, cut off the top third to half of the root, leaving the bottom part to plant. Add a shovelful of compost to the soil that has been loosened to a depth of 12 inches. Plant the rooted cutting at a 45-degree angle, 2 inches below the soil line. A family normally only needs one plant.

How long does a horseradish root take to grow?

A horseradish plant takes about a year to mature after being planted, so if you started planting the root in the fall, it should be ready to harvest the following fall. Horseradish has a one-year growing season, from fall to fall.

How long does horseradish take to sprout?

Depending on the conditions, seeds will grow in 7-15 days. Thin or transplant to 20cm (8′′) apart in rows 40-50cm (16-20′′). The pH of 6.0-6.8 is ideal for the growth of horseradish. The finest soil is well-drained, warm, and in full sun.

Editor: Horseradish is produced mostly for the root, but the leaves are also edible. Similar to arugula and kale, the leaves have a strong, bitter, and peppery flavor. Depending on your preference, you can eat them raw or cooked.

How can you harvest horseradish?

Horseradish is best harvested in the fall, winter, and early spring because cool soil stimulates the development of chemicals that give the roots their pungency. Begin by loosening the dirt around the plant in a broad circle. After that, explore around with your fingertips to see which way the taproot has grown. 

The main horseradish root, rather than descending straight down, runs nearly horizontally in an unknown manner. With your digging fork, gradually excavate the earth around this root. This is the best approach to getting the biggest roots, which can easily break off if you pull plants instead of digging them out.

Clean the roots, dry them, and put them in a plastic bag, store them in an airtight container in the refrigerator. Horseradish, unpeeled, has a mild aroma and can be kept in the refrigerator for several weeks.

What are the nutritional benefits of horseradish?

Horseradish is high in glucosinolates and isothiocyanates, which may help to prevent cancer, combat bacterial and fungal infections, and ease respiratory problems.
