I too have been looking for horseradish. Isabel Sheppard sold me some when we lived on the Sunshine Coast but it died and anyway, you cannot bring plants to Tas.

Head to Chung Sing's vegetable wholesaler in Campbell St and you can buy some if in stock otherwise they can ring the supplier and order some in. Transplant that.

I have grown ordinary radishes, but one is very long, not round like t he ot hers. How do I know if t his is a horseradish please

Iris, horse radish is a completely different plant. It would be unusual if you had some seeds as they are usually grown from cuttings. What you might have is a daikon radish. They grow a long white root.

Ted, Would you be interested in selling some horseradish roots to me? If so, about how many could you supply and approximately at what price?Jan

Ted, with all these people wanting horseradish plants,you should consider filling this need with your 'out of control' supply. Plants will grow from apiece of root, so it shouldn't be difficult to send thru the post.Root cuttings are planted in early autumn.

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!
