Anyone know where I can buy a horseradish plant, either from a nursery or online. I live in the Sutherland Shire, in Sydney. Cheers.

Ferndale Nursery in Constantia, Cape Town has plenty horseradish plants for sale. Owner Errol has been growing it for many moons. Around R32 for a nice size plant.

If you are after the plant, it is usually available in spring. I bought one from Bunnings (Hoppers Crossing), which died. What I have growing now is from a friend.

I bought some horseradish through the post from living-mudflower.blogspot They also had a bunch of other perennial vegetables and herbs and seeds for sale. I think they are in NSW somewhere.

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
