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!

I have been looking after a friends plants. One of them was a horseradish plant in a pot. Just one little frail leaf. It did not last. So will I be able to get a replacement now from a nursery? I live in inner city Sydney

It says plant Feb/Mar and you planted Dec. There could be your problem. Yours could be nearly ready to harvest but you still could be having frosts or snow. Not ideal. Take the advise here and plant later. Try your mulch and see how it works.
