See it on our perennial vegetable disease chart (opens in a new tab)At a glance: Horseradish is a perennial vegetable rated hardy to zone 2 in our ratings (winters to -50°F), needs no pollination, and it ripens about Sep 30 to Nov 9 in Missoula (our Missoula estimate).
| Hardy to | Zone 2 to 9. A bare number means the whole of zone 2, colder half included (winters to -50°F). Find your zone with our cold hardiness calculator. |
|---|---|
| Chill hours | About 200 hours (0 to 500). Our estimate. No published figure exists for this variety yet. That's low, so chill is never short here, but it can wake early in a midwinter warm spell. Check your chill hours or see our sources. |
| Pollination | No Pollination Needed. Horseradish is grown for its root and planted from root cuttings, so it needs no pollination and rarely sets seed. Bees may visit the occasional white flowers, but it is not an orchard pollenizer. Bloom group is our estimate from the variety's origin and relatives. Pollination Charts. |
| Ripens | About Sep 30 to Nov 9 in Missoula (a Missoula estimate from published sources). Real years swing about a week either way. See the date for your town. |
| Good for | Perennial vegetable (8/10), canning and freezing (6/10), winter storage (6/10). Scores are our own 1 to 10 ratings; 8 and up makes our Best Of lists. |
| Deer | Rarely bothered by deer. |
| What you get | Bare root, 3 Root Cuttings. Shipped or picked up in Missoula in spring, roots wrapped in moist sawdust. Guaranteed to bud out. |
Overview
The best performing horseradish we have grown in Montana. Not much to say on flavor because most horseradish we have tried tastes the same. But we're no horseradish connoisseurs here. In terms of hardiness, this will survive down to at least -50F.
Harvesting Horseradish
Harvest can begin the following year once enough root energy has been stored. The saying growing up for us was that you can harvest Horseradish roots in any month ending in "r". However, the colder one is, the harder it may be to harvest the roots once the frost layer is deep, so it is best to harvest the roots in September or October if you are zone 5 or colder.
Bundle Details
Comes with three healthy and good sized root cuttings. When planted, these will take off the first year and produce a good sized plant come end of the season.
Questions we get about Horseradish
How cold hardy is Horseradish?
We rate Horseradish hardy to zone 2, which means winters down to about -50°F. Our ratings come from real winters at our two Montana sites and from trusted growers across the North, not from a catalog average.
How many chill hours does Horseradish need?
About 200 hours of winter chill (we count hours at or below 45°F), likely somewhere between 0 and 500. Nobody has published a chill figure for it, so that's our estimate from its relatives and origin. Horseradish doesn't need much chill to regrow, but it does best where winters are cold enough to make it go fully dormant. Our chill hours guide has a calculator for your winters, and our research page lists the sources.
When does Horseradish ripen?
About Sep 30 to Nov 9 in Missoula, Montana (an estimate built from published sources and our climate). Warmer places run earlier and cooler places later; our ripening map converts the date to your town.
What is Horseradish good for?
Our top use scores for Horseradish are perennial vegetable (8/10), canning and freezing (6/10), winter storage (6/10). Anything scored 8 or higher makes our Best Of lists.
Is Horseradish disease resistant?
We don't know yet. Nobody has published solid disease data on Horseradish for internal root discoloration and white rust, so we list it as unknown instead of guessing. That doesn't mean it's weak. Plenty of the plants we grow have never been through formal disease trials. Our perennial vegetable disease resistance chart has every rating, the notes and the sources.
Will deer eat Horseradish?
Rarely. Deer seldom bother Horseradish, though a hungry winter deer will try almost anything.
What arrives, and when does Horseradish ship?
A dormant bare-root plant, roots wrapped in moist sawdust with a vapor barrier, shipped or picked up in Missoula in spring. Sizes offered: 3 Root Cuttings. We guarantee our plants bud out. Stone fruits can be slow, so if one still has not budded out by August 15, write to us and we credit you for the following spring.
