Hi all, I can tell you that Northey Street City Farm in Brisbane has mature horseradish seedlings on sale. I picked up an great plant yesterday for $9...sounds expensive but seeing as it's rare as rocking horse poo to find it's well worth the price for an excellent, healthy plant.

Go hunting for it. First time I found was in an empty lot with sparse but green grass in Christchurch. Second time was by the Taylor river under a willow tree. On the bank. If you familiarise yourself with the leaves and keep a spade handy, its not difficult to find. It grows all over the place.

Bonjour Francine, I had been looking for horseradish or "raifort" (the French name) myself for a while and just found a healthy horseradish seedling today at the Masters Hardware Store in our Melbourne suburb, quite cheap. They may have some also at a store near your place.

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
