Look on the internet under 'horseradish' plants for sale. Some of the herb nurseries will have it. Alternatively look up garden clubs or Permaculture groups. They might give or swap a piece of root to get you started. All the best.

I love horseradish with beef. The plaants can spread rapidly in good conditions so unless you want that plant them in a very large tub on top of the ground or sunken to just below the rim. Good water supply, and plenty of old manure will yield you tender flavousome roots. Mulching thickly will conserve water. TAll the best!

Do you have a good recipe for Horseradish sauce (pretty hot). I have it growing very successfully in a large deep (about 3 ft or 1 metre tall) pot next to the parsley and mint. I would like to make a sauce or cream which is spicy and with good keeping qualities. Many thanks for your interesting page.

Hi Catherine, I use to mix the horseradish with beetroot and use it as a salad next to grilled steak or sausages. It is delicious! Ingredients: 3-4 small beetroots 1 small horseradish root Salt Splash of vinegar (optional – don’t use if using horseradish from a jar as it normally already contains vinegar) Mustard seeds (optional) Cumin seeds (optional) Method: 1. Rinse any mud off the beetroots and put them in a saucepan (metal is best; it might stain enamel) and cover them with water. 2. Bring the water to the boil and leave to boil for 30-40 minutes. 3. Drain the now very purple boiled water from the pan and refill with cold water and allow the beetroots to cool enough to be handled. 4. Clean off the skin (you should now be able to rub it off with your fingers, but use the flat of a knife to scrap it off if you like) and trim off any roots or stem stubs. (You can bake the beetroot and it will be more tasty and healthy) 5. Cut up the beetroots – you can grate it, julienne it, cube it, slice it...whatever you prefer. 6. In a separate bowl finely grate the horseradish. Be a bit careful here if you’ve never grated horseradish before as it’s tremendously powerful – I recommend you don’t hold your head over the bowl whilst grating it! 7. Teaspoon by teaspoon, add the horseradish to the beetroot and taste until you reach a combination you like. Don’t just throw it all in at once because if it’s too strong it’s hard to correct. Horseradish from the jar normally isn’t as powerful as fresh horseradish so you might need a few extra teaspoons. If you have any horseradish left over, put it in a small jar with some salt and vinegar and keep it for a dressing next time you prepare some beef or lamb. 8. Check the seasoning and add some salt and a splash of vinegar if you feel it needs it. 9. You can, at this point, add some mustard seeds (about a heaped teaspoon) or a sprinkle of cumin if you like these flavours. Mustard seeds aren’t so strong but be a little careful with the cumin as it can overpower. 10. Serve! Enjoy!

I have only made a smooth, semi creamy sauce so can't help you with a recipes. Try Googling 'horseradish sauce recipes', you will find plenty. Trust this helps.

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.
