Hi Ulla I buy my horseradish plants from a nurserywoman at the Hawkesbury Farmers Market. I have taken her advice and always planted my horseradish in a deep pot into the soil as it can become rampant and hard to remove if it gets away. Best wishes.

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
