I do not like horseradish, but I am a seed and plant maniac.Yesterday (Sunday 18th May 2014) I found dryish pieces -roots- at our local PnP in Lambton, Germiston. I will re-hydrate them to hopefully revive them and see if they will grow. Will keep you posted.

OK due to overwhelming demand I only have enough for about 4 more people at this stage. Who would have thought it would be so popular... not me thats for sure! To those of you who have requested roots, as soon as your postpack arrives I will dig and send them for you. Thanks Travis

Have you found your horseradish yet? I can let you have a few plants if you're still looking, I don't have many, but it should do for your own use.

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
