Growing horseradish

queenscook Apr 21, 2011 11:31 AM

Can anyone tell me if I can plant the root end of the horseradish I used for my Passover seder and get a horseradish for next Passover? I live in New York City (zone 7), with a small yard in front with northern exposure, and a sunny strip in the back with southern exposure. If it could be done in a pot, I have a back porch (easier to access than the strip in the back which is downstairs, out the basement), which is very sunny.

If this can be done, can anyone tell me how? Thanks.

    I plan to do exactly that! I saved the thick end - the one that is knobby and has a few small leaves coming out of it - and will plant it in a corner of my garden as soon as I get a minute. It should grow, but I'm experimenting so I can't be sure of anything. Horseradish is an extremely hardy plant - the leaves are long and tough and I suspect it can be grown just about anywhere.

      Never done it but sounds very easy. It can take over.

        I unfortunately planted horseradish next to my vegetable garden a few years back. The stuff spreads, you can't kill it, and the smallest piece left behind when dug (and it grows VERY deep) keeps it coming back next season. Avoid the same mistake.

          I can't find any in garden centres around the city, so I am hoping I can plant one from the produce aisle too if I find one!
          I heard it spreads like crazy. I might put it in a remote corner (acreage living is great for that!) or in a pot.

            Don't know what city you're in; I just saw it today in a Queens, NY garden center.

            I've had second thoughts about planting it, though, because of the spreading I have now been reading about. It'll be safer to just buy my horseradish for next Passover!

              I grew my own horseradish. Sort of a big mistake. Unless you have an enclosed area (think a "brick vase" type of contraption) in your yard, warn your neighbors if you plant horseradish.

                I am in Calgary, Alberta. I planned on putting it in a pot I think. I heard about the spreading. However, it is tough to get fresh horseradish here in supermarkets. It would be handy to have in the garden

                  Definitely use a pot, don't plant it anywhere in your yard. Invasive is putting it mildly.

                    So I bought one and planted it in a big pot (plugged the hole!). How long does it take to show some growth? I mean does it show something on top in a few weeks? Never really seen one growing I think...

                      Generally 4-6 months.

                      Horseradish, when grown commercially, is usually planted in the spring and harvested in the winter.

                      But for our purposes, just make sure the soil in your pot is moist, has some nutrients, the roots are planted far enough away from each so that they can spread, and you should be good to go in no time.

          Update. As promised, I planted the thick end of my horseradish root and it's coming up nicely. I put it outside my garden fence but beside it. As long as my husband doesn't mow it down, it should be ok there. Will post further updates as required.

            Big mistake. You'll mow, dig, and spray but you'll have pesky reminders a very very long time...

              Ugh. There goes the rest of your garden unless your fence extends all the way to the earth's core.

                I'll get my husband to do it. No problem.

                  I still wonder how the people who bought our first house back in the 80s are dealing with the horseradish. I had only planted it a few years earlier and it had taken up at least a quarter acre already. I guess if you keep it mowed you might not notice.

                    I'm hoping that our cold winters will slow down the monster. I guess I have to start planning my horseradish factory now...

                      It will slow them down I think. But the cold simply puts them into a sort of state of hibernation (probably not the right word). They don't die, but simply lay dormant ... waiting for the first ray of sunshine.
