Most European/Italian greengrocers will have it just now.Bought 100gm Tues.@$39.00 p kg. Most to grow in old holey buckets, H/radish can dry out quite quickly if not mulched. Keep eyes on leaqves, some pest find them quite yummy. Keep healthy.

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.

I would also like some fresh horseradish roots. Would be willing to reimburse any costs. [email protected] Thanks Simon.

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.

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

My horseradish has been in a trough approx 60x30cm for years and never harvested, the new leaves are shooting. Can I repot or plant it in the ground now?
