Seeking horseradish seeds looked up EBay and sent away for Russian variety Has stronger flavour and pest resistance is higher. The seeds arrived via Air mail in sealed pack. Be ware the pack of seeds can cover 4m square Each plant can yield 4kg horseradish!! Happy growing!

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
