Try the Digger's Club online - I bought my plant from them.

Can I just plant a piece of horseradish root that I've bought at the market?

Hi Lori. from my experience with horseradish you certainly can grow H. from a root cutting. Beware horseradish can become invasive so plant in a large pot and bury in the garden. this should contain the roots. I am having trouble removing horseradish from a large garden bed. every time the bed is dug a piece breaks off and away goes the h.radish again!!! good luck.

I am also interested also in how to grow it and how to obtain it.

Gail I purchased a plant at flowerpower a few years ago and planted it in the ground and left it alone until about may- I then pulled it out and cut the root into small pieces about 5cm each and put it back into the ground. It grew and the plant has large green leaves - you can begin to use it in the second year. I pull one out - grate what I need and put it back into the ground. I am sure you will be able to buy it on eBay as well.

I have horseradish growing in a large pot, all I get are long thin roots... I still use them all the time though as there's nothing like fresh horseradish. What do I need to do to get a fatter root from the plant? Many thanks. Gill :)

Hi Jackie, I know it was a long time ago, but do you still have any horseradish in Launceston ? I am in Beaconsfield and would love to grow some so I can make Fire Water with it. Donna.
