I bought some horseradish through the post from living-mudflower.blogspot They also had a bunch of other perennial vegetables and herbs and seeds for sale. I think they are in NSW somewhere.

Hi Lilly, saw your post and was wondering where you bought your horseradish. I also live in the Sutherland Shire in Sydney. Would appreciate if you could advise. Cheers, Gaye

I have grown horseradish several years in a row & havent managed to harvest a decent root yet. It sprouts up year after year but is all leaf & no useable leaf. What am I doing wrong?

I haven't grown it yet and have just bought a small plant. Plant in the full moon week as it is for root growth.

Do I need to dig up all my horseradish or just what I need to make horseradish recipe. If I need to dig all how and for how long can I keep roots
