Hi Clare, I'm a huge fan of horse radish, but a newbie to vegetable gardening. I would love to give growing horse radish a try if you have another piece of root spare. Happy to pay costs.

Try googling about how to grow horseradish. Look up seed selling companies to buy it.

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.
