I bought my horseradish root through Greenharvest.They have a list of edible spring plants that they sell from July each year - They currently have no horseradish available, but they did say that this year the crop wasn't very good. Maybe try again next year if you haven't found some by then?....

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.

As regards horseradish, I have grown this plant, but in my opinion, it would be a mistake to think you can plant it in April and harvest in 24 weeks time and have a useful root. For Horseradish to get a nice thick root, with the distinct pungent flavour, it takes a good two years per plant. And do not underestimate how much work it is to clean the dirt out before shredding the root. It is a wonderful taste and worth the hard work, but in my experience, you need to set up a dedicated bed, plant the roots and then prepare to wait a few years to get the cycle of having a constant supply of usable nice thick roots. The roots grow very deep into the soil (a good 2-3+ feet) so it is a good idea to leave some room around each group of plants, because you need to dig quite a wide hole to get the roots out. We always harvest at Easter here in Sydney. Bon apetit.
