under no circumstance leave pieces of root in an unconfined area as it multiplies ex potentially and becomes very hard to eradicate. i have dug up and confined any and all my 'cuttings/broken pieces' which sprouted from residues of deeply sited broken roots into plastic bags of 'growing compost'....good luck with the 'digging up'!

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.
