How Long Does Horseradish Take to Grow?

Horseradish can be grown from crowns or root clippings that are sown 4 to 6 weeks before the usual final frost season in your location.

Horseradish is finest cultivated as just an annual because it is a resistant perennial. Plant horseradish in a pot to prevent it from expanding in the yard.

Horseradish is a tough annual planted for its bitter roots, that can expand to be 2 feet (.6m) tall and narrow.

Horseradish is best grown as a perennial since the roots might become rough and stiff in the following year. Horseradish is best cultivated in pots since it grows quickly and could become out of hand.

Horseradish can be harvested 140 to 160 days after it is planted. Horseradish is a tough, cold-hardy plant that thrives in areas in which the cold is long enough to put the vegetation into hibernation.

Horseradish comes in two varieties: regular horseradish, which has wide, crumpled leaves, versus Bohemian horseradish, which has thinner, smoother leaves.

Guide to Getting a Herb or Veggie Yard Started Growing Horseradish:

Horseradish mixes are available for purchase. Small root pieces (commonly referred to as horseradish sets) are frequently planted straight into the underlying soil while growing horseradish. Horseradish sets are widely accessible in stores, grocery stores, as well as nurseries.

Select the soil. Horseradish may be cultivated in a wide range of soil types, although it prefers mildly acidic & loamy soils with a pH of 6.0 to 7.5.

Select a growing location. To allow adequate area for the root systems to grow without affecting your existing plants, maintain your horseradish sowing location at least one and a half to two feet apart from other crops. Horseradish should be planted in full sun or light shade.

Allow space for root systems to grow. Horseradish taproots spread fast and can reach a depth of up to a foot (or more, if left unattended for too long). In clear, sandy soil, create a hole 3 to 4 inches shallow.

The trench must also be large enough for the horseradish roots to be laid at a 45 ° angle, exposed root face down, in the trench.

Plant to keep as a company. Rhubarb, sweet potatoes, as well as asparagus, are all great horseradish accomplices, and though don’t plant them excessively close around each other.

Horseradish roots require space to expand, and they may contend for supplies or dismantle the root systems of neighboring fruits and vegetables.

Selecting a Location

Horseradish grows best in the broad sun but may take some shelter. Horseradish can grow in practically any soil, except chronically wet circumstances.

Since you won’t like to relocate your horseradish after it’s established, plant this in an out-of-the-way location.

From Seeds to Fruit

Assemble the bed as directed above. Make a trench 3–5 inches deep. Top the seedlings with sandy soil or manure and plant them in the trench. Trim seedlings to one foot away after they emerge.

Narrow them out to 2–3 feet off when plants reach 4 inches high. To keep horseradish from expanding in the yard, create 2 foot-deep boundaries all around crops.

Horseradish in a container – how to plant it

To enhance root development, pick a good pot that is at least 500 mm broad & 700 mm deep. Load the container with excellent potting matter and place it in a bright but rather gently sheltered location.

In late winter/early springtime, plant 15-cm-long roots in the potting medium, making the apex of the root 2.5 cm beneath the top.

Because crops in containers wilt much more rapidly than perennials in soil, hydrate them frequently. Cut down the number of sprouts to 2 to 3 when they mature to promote root development.

Horseradish Planting Instructions

Place horseradish in kind of a 3 to 4 inches shallow dig by placing sets or segments of roots approximately 18 inches away as well as at a 45° inclination. The lower part of most sets is chopped off at the angle to demonstrate which side will lean down.

Foliage will emerge from numerous spots throughout the length of a set if completely horizontal sowing is used, which is less desirable. Following planting, fill with topsoil.

Horseradish: How to Grow It

The crops put on a lot of surface development over the summertime and then start accumulating starch in their roots in the autumn, which makes them larger.

Water and trim on a routine basis, but only when the crops are immature. Defend the plants from diseases like cabbage worms or flea beetles, which typically target cabbage relatives.

Harvest its roots regularly—ideally, every springtime or fall—and shift the bed to a different location periodically, planting pencil-sized pieces split from the primary roots to avoid the transmission of bacteria or viruses.

Horseradish Harvesting Instructions

Although farmers debate over whether spring-dug or late-fall-dug horseradish has the best flavor, many believe that summer-dug roots are unappealing.

After the greenery has been eliminated by cold and just as the soil freezes, they harvest their primary source of roots in late October or the initial November.

Horseradish harvesting is just a straightforward procedure.

Dig a hole a foot or so deep solely on a single end of the planted row. Using a fork or shovel, separate the roots from the opposite end of the row.

Take the plants’ crowns and carefully pull them out of the ground. Prune the leaves to approximately an inch from the ground. Trim the roots on the sides and at the base.

Keep any that are 8 to 10 inches or taller for sowing cuttings the next year. Knot clean root clippings securely and keep them in damp soil in a cold, dark spot around 32 and 40 ℉ if you’re overwintering seedling stock (0-4 C.).

To prepare the root to be used as a dish, clean them thoroughly and peel them. Chop into half-inch pieces and blend with 1/4 cup water and cubed ice inside a food mixer or blender.

Allow 3 minutes for the purée to sit before adding 2-3 tablespoons white wine or even rice vinegar plus 12 teaspoons salt per cup of horseradish purée. Mix the vinegar & salt right upon pureeing if you would like a milder sauce.

Use a fine strainer or cheesecloth to filter most of the fluid if that’s too sloppy for your liking. The finished product can be kept in the fridge for approximately 4-6 weeks in a closed container.

How to Keep Horseradish Fresh

Trim the leaves to around 1 inch in length and rinse the roots using running tap water, wiping away all impurities. Let the roots dry completely before storing them.

Horseradish should be stored in moist sand in a dark corner of the root cellar. It is not advisable that temperatures drop past freezing.

A little number of roots should store well in a zippered plastic sack in the fridge for up to two months for even more instant usage.

Peeling or scraping the roots is by far the most popular method of preparing horseradish for consumption. Shred the root in white wine vinegar or even distilled vinegar straight away.

Cider vinegar should not be used since it creates discolouration in the shredded horseradish in a matter of minutes. You may mix the vinegar according to your preferences.

After shredding the horseradish, jar it and seal the bottles as quickly as possible.

To keep the pungent flavour, keep it refrigerated on all occasions. Newly grated horseradish would only last a couple of weeks.

After that, make a new stock. Horseradish could also be dried, crushed into a powder, and stored in containers in a dried form. Dried horseradish lasts considerably more than newly shredded horseradish, although it’s hardly as good.

Horseradish Plant Maintenance


Horseradish plants may survive a little shadow, although their yield will suffer. On most occasions, they need to get at least 6 hours of bright sunlight.


The finest roots should grow in the soft, well-draining ground with plenty of natural matter. Horseradish likewise prefers a little acidic to balanced soil pH.


Horseradish does have a low water requirement. Woody roots with such a faint flavour can develop from a lack of water. Excessively water, on the other hand, can result in weak roots with a pungent flavour. It’s best to get 1 to 2 inches of fresh water each week.

Moisture and Temperature

Horseradish prefers chilly temperatures. It thrives in temperatures up from 45 to 75 ℉, with ideal conditions reaching 60 to 65 ° F.

Humidity is usually not an issue especially as the vegetation’ soil moisture standards are fulfilled and there is adequate air circulation around them.


Fertilize young horseradish when you first saw it and then every 4 weeks or so after that. Organic material, compost tea, or a synthetic 10-10-10 plant fertiliser could all be used (following the product instructions).


On the horseradish leaf, the horseradish flea beetle is a major pest. It lays egg groups on the petioles of the blades. The larvae dig into the petioles of the leaflets, killing a few of them.

To keep the Beatles away, gently scatter wood ashes upon that plant. Insect protection in the yard is better accomplished by proper cleanliness techniques.


Horseradish can get root rot every time to time. To serve as a planting resource, just use disease-free roots clippings. Growing locations should be alternated after 3 to 4 years to avoid growing horseradish in the identical spot.
