Horseradish is grown from root cuttings. If you know someone who has it in their garden, just one piece of root will start off for you.

Dig a deep hole and refill with compost as the horseradish has a long taproot. Plant it and then leave it alone. Apart from constant wet or cold, horseradish will grow in any part of the garden.

Horseradish is an aggressive grower and will quickly take over the garden. It will also grow well in a deep container or sink an old bucket in the ground to prevent spreading. Otherwise, remove all the plant when you harvest it and save one piece to replant.

Can be planted in early Autumn or Spring

Do you have a good recipe for Horseradish sauce (pretty hot). I have it growing very successfully in a large deep (about 3 ft or 1 metre tall) pot next to the parsley and mint. I would like to make a sauce or cream which is spicy and with good keeping qualities. Many thanks for your interesting page.

Hi Catherine, I use to mix the horseradish with beetroot and use it as a salad next to grilled steak or sausages. It is delicious! Ingredients: 3-4 small beetroots 1 small horseradish root Salt Splash of vinegar (optional – don’t use if using horseradish from a jar as it normally already contains vinegar) Mustard seeds (optional) Cumin seeds (optional) Method: 1. Rinse any mud off the beetroots and put them in a saucepan (metal is best; it might stain enamel) and cover them with water. 2. Bring the water to the boil and leave to boil for 30-40 minutes. 3. Drain the now very purple boiled water from the pan and refill with cold water and allow the beetroots to cool enough to be handled. 4. Clean off the skin (you should now be able to rub it off with your fingers, but use the flat of a knife to scrap it off if you like) and trim off any roots or stem stubs. (You can bake the beetroot and it will be more tasty and healthy) 5. Cut up the beetroots – you can grate it, julienne it, cube it, slice it...whatever you prefer. 6. In a separate bowl finely grate the horseradish. Be a bit careful here if you’ve never grated horseradish before as it’s tremendously powerful – I recommend you don’t hold your head over the bowl whilst grating it! 7. Teaspoon by teaspoon, add the horseradish to the beetroot and taste until you reach a combination you like. Don’t just throw it all in at once because if it’s too strong it’s hard to correct. Horseradish from the jar normally isn’t as powerful as fresh horseradish so you might need a few extra teaspoons. If you have any horseradish left over, put it in a small jar with some salt and vinegar and keep it for a dressing next time you prepare some beef or lamb. 8. Check the seasoning and add some salt and a splash of vinegar if you feel it needs it. 9. You can, at this point, add some mustard seeds (about a heaped teaspoon) or a sprinkle of cumin if you like these flavours. Mustard seeds aren’t so strong but be a little careful with the cumin as it can overpower. 10. Serve! Enjoy!

I have only made a smooth, semi creamy sauce so can't help you with a recipes. Try Googling 'horseradish sauce recipes', you will find plenty. Trust this helps.

Is it best grown in full sun or shade
08 Feb 17, John (Australia - temperate climate)
Horseradish will grow in full sun or part shade. It is a very hrdy plant and will spread rapidly in good conditions. To contain it you can plant it in a large planter pot and sink the pot into the ground. Horseradish loves damp conditions and in this situation will produce the best roots but will still do well with less water. Trust this helps

It's 30th Dec 2016, my horse radish leaves are about a foot long, should I dig it now, if not, when thanks

Horse radish would normally be harvested when it is dormant but there's no reason why you couldn't dig down beside the plant an bandicoot a few roots for your favourite source! Horseradish is very hardy and any piece left in the ground will grow. Trust this helps.

When should I harvest my horseradish ? Very leafy i its own raised bed and looking real healthy
24 Dec 16, John (Australia - temperate climate)
Horseradish would normally be harvested in the winter when it is dormant but there is no reason why you couldn't dig down beside the plant and raid a few root pieces. the plant is almost indestructable and any small pieces of root left in the ground will grow. keep the manure, water and mulch up for good quality roots. trust this helps.
