I can get horseradish for you, but they will only be small plants, but now is the time to plant them out, and ready to harvest in autumn. I live in Kersbrook, so not far from you. Anyone else wanting horseradish, I can post to you if you like. Just send me your address. Cheers Cheryl (It's probably best to share email addresses on this forum -Liz)

Bought some from my local bunnings in busselton, WA. Look for them in herbs section. They come in already established. Haven't got a chance to plant them yet, its still quite cold and windy.

Margaret, I haven't found the perfect time, the size of the leaves don't tell me anything. Last week I did use some, just scraping away surrounding soil and seeing the thickness of the root helped, the root was fairly thick, about the same as two fingers plus a little more. Getting it out is the hard part, the roots go down a long way so I cut the amount I needed and replaced the soil. Be careful if you do this because the root is very strong, a serrated knife worked o.k
