I have horseradish growing in a large pot, all I get are long thin roots... I still use them all the time though as there's nothing like fresh horseradish. What do I need to do to get a fatter root from the plant? Many thanks. Gill :)

Hi Horseradishers! I've just seen this thread. I'm also seeking some horseradish to start me off. If anyone has some left, after all this enthusiasm, please could you post some to me? I can send stamped self addressed post pack.

You can post it in a sealed lock bag wrapped in paper. The few days it is out of soil wont bother it. I would love to have a piece, if you could send me a piece I' happily pay you for it, plus postage costs. Please let me know how to pay you. Many thanks

As an ex South Australian we had a large patch of horseraddish in the back garden in the 1950's. My mother used to make it fresh when we had roast beef which in those days was quite often. I now live in Qld. Horseraddish is hard to find as a root in any supermarket although I've found a specialty providor who sells it along with the famous Newman's in the jar which is still the best if you like it strong. The root keeps quite well. You could post it in a small plastic bag. This bag can then be put in an envelope. I would like to try growing it in Queensland. We grow a wide range of vegetables both in the garden and hyponically. I'm happy to pay for some roots and would transer funds to cover pack and postage. Look forward to your response, Bill Lodge

Hi Charles I would very much like come horseradish planting material. I am located In Hackett, ACT p/c 2602. If you use a standard Aus Post satchel say 500gm it would be easy to post. Let me know the cost & your address & I will send you the money ( & a nominal amount for your trouble) first. Hoping to hear from you, yours sincerely Greg Greet

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
