No problem! Please let us all know how they turn out!Just a word of caution - protect your eyes when grating old horseradish - it will burn your eyes. Use swimming goggles. I know people who didn't realize this until it was too late - they got a chemical burn, took a week to recover. Cheers!

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.

is the horseradiah plant frost hardy?
23 Jan 12, Jen (Australia - cool/mountain climate)
Hello Brian, I would say yes, as I have mine planted in a big 42 cm wide pot but did not move it into "winter quarters" as I do with my Kaffir Lime potted tree, it showed no damage over the years, Happy gardening Jen

Yes, ours certainly seems to be stronger after a second year but the roots are very spindly and they are not easy to peel. Any tips on growing a thicker root? However, to make the sauce and not being too keen on hand grating, I first grated the root with the food processor. This gave thin matchsticks but also lots of lumps, then I added some vinegar and used the chopper to cut it finer and it worked well. I also added some hot mustard to give it a bit more zing.

Can anyone please tell me where I can buy fresh horseradish. I'd like to grow some in my garden and I live in Perth.

Just thought I'd mention I found horsradish plants at Mitre 10 today in Westport. I've been looking for it for a very long time so was very happy. Other Mitre 10 store may have it now.
