In addition to being democratic in the kitchen , the horseradish plant has its fan – and a history – in the medicinal plant world , too .
Let ’s teach more about this plant ’s many uses , and then get down to clientele with the planting and harvest home . Here ’s what we ’re going to discuss :
What You’ll Learn
Horseradish is n’t what I ’d call a common backyard flora , but it has been around for a foresighted , long clock time .
pop as a medicinal and eatable specie , we ’ve been cultivating it since at least 100 AD . have ’s explore the origins of horseradish root .
Cultivation and History
Horseradish is amember of the Brassicaceae kin , the same group from whichcabbages , Brassica oleracea italica , andbrussels sproutscome .
And while we ’d typically have-to doe with to the root word as a vegetable , the medicative and culinary applications of the leaves and flowers direct many gardener to call this plant an herb .
Horseradish is assumed to have develop around what is considered modern - day Russia , western Asia , and southeastern Europe , which should tippytoe you off about this works ’s cold - loving nature .
As former as 100 AD , the plant had made an visual aspect in De Materia Medica , the definitive usher to medicine in Ancient Greece and Rome . In the book , it was touted for relieve cramps and back pain .
By the 13th hundred , it was being cultivated throughout the Nordic land as a spiciness and a medicine .
The plant also plays a historical persona start in the eleventh one C in the Passover Seder plateful as one of the sulphurous herbaceous plant , an important tradition of the Judaic faith that cover to this mean solar day .
This aromatic came to North America during the time of European colonization , with commercial production commence in the mid-1850s .
Horseradish sauce was one of the first condiment produce and sell in the US . Collinsville , Illinois , where it was first sold by John Henry Heinz in new clear glass nursing bottle to show off its timbre , still holler itself the “ Horseradish Capital of the World . ”
The leaves , flower , and rootage of this flora have been used medicinally throughout story as everything from a cure for scurvy to improving blood flow . It has also been used as a fungicide and pesticide .
The leaves are said to be an analgesic , the heyday are made into a tea that is said to fight colds , and a compound in the root has been show to have antibacterial attribute .
The leaves go forth from the long taproot in a little potato , much like blowball do , and they are farseeing and obscure dark-green .
Flowers have four blanched flower petal and form at the end of the stalks .
The root grow up to a substructure deep and is n’t just full of smack , it ’s intelligent too . It ’s packed with vitamins C and B1 , as well as iron , calcium , Mg , and potassium .
The barbed bite gadget characteristic of the root word is triggered by the sulfur - carry chemical compound allyl isothiocyanate . By the way , this chemical compound is also responsible for for “ garlic breather ” and is found inalliums .
If you ’ve ever accidentally taken too big of a sting of horseradish - based wasabi and ground yourself near blinded with nasal annoyance , you were slapped by the allyl isothiocyanate , which acts likewise to capsaicin in the body .
You could say that your sushi tiffin bust - gassed you .
This compound allow protection against insects that might be tempted to take a nibble out of them .
Humans ( or some of them , anyway ) not only enjoy the flavor , but some are try out to harvest this chemical compound commercially for use in nuisance direction .
Speaking of wasabi …
A Note on Wasabi
Wasabi , sometimes call Japanese horseradish root , is actually a totally different plant : Eutrema japonicum .
In North America , of course , we know wasabi as the fiery accompaniment to sushi and sashimi .
But because honest wasabi is very difficult to train outside of Japan , what is sold and do here is very seldom the real deal .
Instead , we usually get dry land Armoracia rusticana mixed with green food discolour and other seasoner .
you could learn more about growing wasabi in our guide .
Horseradish Plant Propagation
Horseradish semen are n’t ordinarily available to the home cultivator .
These industrial plant do n’t readily get viable seed because many plants are ego - inappropriate and will reject pollen from themselves .
This is a smart evolutionary strategy because it diversifies the gene pool , but it ’s not so great for our cum propagation efforts .
It ’s possible to multiply unrelated clone and farm viable source , but since using set ( or crowns ) work so well , that ’s how it ’s mostly done .
Horseradish is propagated by choose root cutting about as thick as a pencil , which are sometimes called “ sets . ”
If you purchase sets , the grower will generally ship them with the side that should be front down cut at an slant and the side that should be up is flat .
If you harvest your own , you might want to trim them in a like way to remind yourself how to plant them .
And in causa you were wonder , yes , you could imbed the ones you purchase at the grocery entrepot .
blank space the Seth one foot aside , placing them at a 45 - grade slant , with the square - cut end high than the angled close .
Ensure that the hearty swing ends are all facing in the same charge so that the leafy tops will grow equally spaced .
incubate the sets with two column inch of soil and urine well . Keep the dirt moist as the plants develop .
When you harvest the roots , cut away a piece that include a root and one leaf tip and replant it for a perpetual harvest .
How to Grow Horseradish Plants
In line to its juicy - hot nature , this plant is affectionate of cool status . It does well inUSDA Growing Zones2 to 9 , but meter your plantings according to local conditions patterns .
This plant life probably wo n’t exist a hot summer in Zone 9 but will make a pure winter crop there . In Zone 2 , late summer might be your best option .
Aim to embed when you ’ll have 140 daytime when the daytime gamey temperatures will range from 45 to 75 ° farad . The radical tastes well after a Robert Frost has kill the leaves , so take that into considerateness . But a freeze is n’t necessary to produce a tasty veggie .
Before planting , work lots of well - rotted compost at least six inch deep into the ground . If you ’re grow a larger cultivar , repair the grease as late as the root will grow . Compost improves drainage and H2O retention while total nutrients .
Remove each and every careen you chance as you go . The ground should have a pH between 6.0 and 7.5 .
If this is just too much excavation and amending for you , industrial plant in a raised bedor container filled with on the loose , loamy , pee - retentive soil .
uprise in a container is also chic if you ’re distressed about this flora spreading where you do n’t want it to .
Whichever way you go , just know that ensuring you have loose grease will bear off big at harvesting time . John Rock will cause misshapen ontogeny and heavy soil will result in a little , tough ascendant that might fall apart as you render to take it out of the ground .
Plant sun - loving horseradish somewhere that will receive at least eight hours of lineal sunlight per Clarence Shepard Day Jr. .
Another consideration : these plants can grow as tall as three invertebrate foot , and their big foliage may shade out surrounding vegetation . If you hold out somewhere that will belike be hotter than what this plant prefers , give it a petty afternoon refinement .
While horseradish is drought kind , the roots can become woody and frail - flavour if they go for too long without water .
If rain is scarce , give the plants one to two column inch of water once a workweek . But take care not to give them too much water system , because the tooth root will become soft and have a biting flavor .
Err on the side of providing more body of water rather than less . If you ’ve evergrown a tomato , horseradish like similar wet levels . If the leaves start to droop or even turn teetotal , you ’ve have the stain dry out too much .
If you havea pelting gauge , you could rely on that to say you when to irrigate . But I like touse a moisture meteror simply cohere my finger into the soil .
That ’s because you never sleep together if the filth is dry out more rapidly because of a hot spell with lots of breaking wind , or if one part of the garden is dry out quicker than another .
tot up water when the top inch registers as dry .
How you water supply is as important as how much you water . It should be done infrequently but deeply . You want that moisture catch all the agency down below the long taproot .
Place an inch ofstraw , leaf , or shredded bark mulch around but not touching the plants to bottle up weeds and retain wet .
Unless you’vedone a soil testand your dry land register as wanting in something , bung your plants four and eight weeks after planting with a veggie - specific nutrient or any soft , balanced fertiliser .
If you ask me , I ’ll always commend Down To Earth ’s Vegetable Garden fertilizer . It has an NPK of 4 - 4 - 4 and comes in a compostable corner .

Managing Pests and Disease

Both feed on the leaves , and while this can make the leaves ugly , they also spread disease . address these bugs with insecticidal soap .
Unlike pests , disease can be a serious issue for horseradish . Like most brassicas , fungi just ca n’t get enough of these plants . Here are the giving ones to be aware of :
Leaf Spot
foliage spot is caused byCercospora amoraciaefungi . It results in small , purple - peal spots and thrives in cool , humid conditions .
get word more about Cercospora identification and control in our guidebook .
Rust
eat in horseradish plants – and all crucifers – is because of an oomycete calledAlbugo candida . It causes little white fungus - comparable spots on the leave-taking or stems of the plant .
When these pustules “ pop ” during nerveless weather at temperatures between 55 and 75 ° F , they release pathogen that travel on wind or H2O onto other plants .
If your plant is infected , trim off any infected foliage . apply extreme caution not to splash pee on the plant – piddle at the territory tier only to keep contagion or keep further bedspread .
When it ’s meter to harvest , pull up the entire flora and dispose of all the green parts – do n’t put them in the compost . you may still feed the ascendent but do n’t replant any part of an septic specimen .
Turnip Mosaic Virus
Sure , the name says “ Brassica rapa ” in it , but turnip mosaic virus ( TuMV ) infects horseradish works , too . When infect , the leaves will train angular yellow spots and may eventually go . You might also see sinister run on the stems .
