How To: Plant & Grow Horseradish Root


As mentioned a few times here in the past month, Mary and I have been eager to get back outside and get our urban gardening projects going again. While it's still too cold for most projects we've been tackling a few smaller plantings we'd hoped to get to. One we have high hopes for is the horseradish root we just planted.

The picture above shows what horseradish root looks like straight from the grocery store. We've been excited to try growing horseradish root for a few reasons. First off, it's a perennial, meaning it will come back every year without us having to do much at all — you just dig up the root after each growing season and cut off what you need before putting it back under the soil. It's also supposed to be a super low maintenance plant once planted if left in a sunny area with occasional watering. In researching how to plant horseradish, we also learned of the root's many health benefits, and that it's a member of the Brassicaceae family, which also includes mustard, wasabi, broccoli, and cabbage.

But by far the best part? I'll now have an unlimited supply of fresh horseradish to grate into my Bloody Marys from here on out. Just joking. Kind of. Aside from Bloody Marys, horseradish can be used in a variety of culinary ways — which of course I'm excited about.

If you're not grating the entire root at once, it can be stored and used for months by keeping the main root in a sealed zipper bag in the refrigerator. Just cut off the pieces you'll use to grate and keep the main root sealed and stored.

We'd had this root for a while before wanting to plant it, so we kept it sealed in a zipper bag like below in the bottom fridge drawer in order to force/mimic it's natural dormancy stage until we were ready to plant — it's that simple:



We've heard it's also a plant that takes really well to container gardening since the leaves and roots can spread and take over the area of ground it's planted in otherwise. Also, the leaves can get up to 5 feet tall, which would look pretty awesome coming out of a container, right?

Since we wanted to give the root ample space to grow and multiply, we decided the size of a paint bucket would be just right for what we needed. Our neighbors are painters and always have extra buckets they pass over the fence our way, so we've got a good little supply of buckets going.

Since paint buckets can get the job done but aren't the most visually appealing planters, we decided to gussy it up by wrapping it in one of the burlap coffee sacks we had on hand from Blanchard's Coffee here in RVA:
 


I just drilled some drainage holes in the bottom of the bucket and then placed it inside the coffee sack:


Once inside, I inverted the upper portion of the coffee sack inside the bucket and wrapped the remaining bag neatly around the sides. Not only will the coffee sack disguise our little paint bucket secret, but should help provide another layer of good drainage for the soil.

 

Speaking of soil, we were finally able to use some of the compost we've been building up over the past year from our compost bin!



I told you it was still cold here in RVA — yes that is snow on the ground! 

So, I filled the bucket 3/4 of the way with a mixture of dirt and compost:


Then it was time to plant our horseradish root:


The only trick to planting it is in making sure to place the root in the dirt at a 45 degree angle with the top of the root facing up — you don't want the bottom of the root facing straight down. The wider tip is almost always the top of the root, where the leaves will sprout from.

See how it's at an angle here — this is what you want:


Then I just topped off the rest of the planter with more dirt/compost and we took it up on the top landing where we see the most sun:


Mary smoothed out the remaining coffee bag flaps and secured the whole thing with a few wraps of garden twine:




So this is where we are currently! All planted and ready for this little horseradish root to begin working its magic underneath the soil as we head into what the groundhog predicted as an early spring. 


We're loving the idea of such a low maintenance plant with so many added benefits — we'll be sure to keep you posted as we progress (or don't) with this guy. In the meantime, I'll be dreaming of future Bloody Marys, raw oyster toppings, and a side for steak with that fresh added horseradish kick.

  2. Any follow-up on your horseradish planting? I've a root we picked up at the grocery yesterday, and want to get it into the ground.

    Would love to see how yours turned out!

  3. I just stuck mine in the ground and by the end of the season, it was two feet tall and wide. The flowers smell like horseradish and the leaves have a bite.

  4. What parts of the plant is edible and do they like full sun or partial sun this will be my first attempt at planting horseradish? And my family loves it

  5. I have heard that it spreds out and can take over in the garden, so your idea of container planting is very good.
