Be very careful when planting horseradish as it is invasive, confine it to a container.

I have some Horseradish growing but cant get it to grow in to any thing of consequence, it spreads like wild fire but roots are too small to grate. Does anyone have a suggestion please

Sounds like you are using a fertiliser with a high N %. N produces grow of leaves etc, P is good for root development. K for flowers/fruit. Try and plant them after another crop has used up most of the N.

Hi Keith, Like you, I am also keen to get some horse radish plants as the stuff you can buy here is only the creamed sort and a bit bland. Did you have any luck finding a source?

Search for some seed selling companies on the internet in NZ.
