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

To get the hottest flavor when preparing horseradish root: DO NOT add vinegar while grinding the root! If you're using a food processor, add water, just enough to get it to grind well. Once it is fully ground, let it sit for about 5 minutes. THEN add vinegar. During the 5 minutes, the horseradish (once ground) undergoes a chemical reaction that makes it much stronger. The reaction is (I believe) with water, triggered by breaking up the cells. Vinegar stops this reaction; if you do it too early, the heat never develops. But after a few minutes, without vinegar, the heat will start to fade, so you add vinegar

Judy,, so here was I looking for a recipe (another dish) when I came across this one for horseradish sauce but alas no mayonnaise. Horseradish sauce - Traditional Ingredients. 4tb Grated Horseradish 1tb Caster Sugar 1ts Salt 2 ts Mustard, English 1/2sp Pepper 4tb Single cream A little malt vinegar can be added though this is not recommended. Mix all in a bowl and stir anti-clockwise, and just my suggestion is to substitute the cream for mayonnaise,and I suppose that with most recipes certain ingredients can be left out and others added such as my beetroot and horseradish sauce I add some red wine vinegar. Hope this helps.

best thing you can use horseradish for is horseradish mustard I have a excellent recipe that we have been making in the restaurant for years... But I can not seem to get any at the moment.

Hello Roy, I live between Ballina & Lismore (NSW). Just dug up my horseradish (it's been in our subtropical garden for at least 18 months) and there's almost nothing but slender hairy roots! (But the leafy tops are magnificent!). Google indicates that we should be able to grow it well, but we haven't yet. Any tips, please? Same thing with celeriac. Have you ever tried that in Logan City. (Sometimes we get lost near you - whenever we come up to Ikea. Gonna try and get the correct exit no. showing prominantly). Thanks for your help. Bella

If the soil has too much nitrogen, it will not grow roots well (it doesn't really need thick roots in that case). Horseradish, while delicious, is basically a weed, and does best when treated as such. You want to basically keep it nitrogen-starved. Best soil for horseradish is nitrogen-poor, which causes much better root growth. (Also make sure the soil is loose). Pick the worst piece of dirt you have. Cultivate to about 2 feet deep. Mix in sand, perlite, or coconut coir if necessary, to keep the soil loose. The only nutrients you should add are phosphorus and sulfur (I use epsom salts in water for the sulfur). Only water as necessary. You need to make it struggle a bit for it to put its energy into the roots. I doubt you get frost where you are, but cold weather (and frost) helps the roots develop better flavor. Good luck!
