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

Hi Jan, Try www.theseedvault.co.za. They sell horseradish rhizomes (pack of 3 for R60). I bought some recently and they were excellent quality.

Does horseradish need full or filtered sunlight to grow well on eyre peninsular and how often does it need watering.
15 Dec 17, Mike (Australia - sub-tropical climate)
Can grow in partial shade but most plants need sunlight. A good watering once a week will probably do, Doesn't like too wet.

It's not all that easy to get horseradish crowns or living plants. I've been trying. I love the condiment preparation of the root and also the idea of eating the foliage. Should i get some in It'd be one of the crowning glories of my garden haha!

I am about 10k north of Noosa in the hinterland. Happy to cover the cost of postage and your time. Thanks, Mate, Tony

Just thought I'd mention I found horsradish plants at Mitre 10 today in Westport. I've been looking for it for a very long time so was very happy. Other Mitre 10 store may have it now.

Sorry, that should be ESKAL Horseradish not whatever name I advised.

In most big supermarkets all around northern Europe and Scandinavia you can find all forms. A container of grated horseradish, from the fresh food section, is fine and doesn't last long enough for me to know its 'use by' date. It's good with lots of unexpected foods and it's particularly good with potato soup (makes it far more interesting) as well as beef, which was created to go with horseradish.
