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

I would try local growers markets, traditional green grocers or organic gardening groups. You will find these on the internet or markets are often listed in local papers.

Look on the internet under 'horseradish' plants for sale. Some of the herb nurseries will have it. Alternatively look up garden clubs or Permaculture groups. They might give or swap a piece of root to get you started. All the best.

Bridget Kitley Herbs in Stellenbosch list it in their range. They may post a bare rooted plant wrapped in damp newspaper and plastic. Contact them on 07 9407 2209 or email: [email protected] . Trust this helps.

I love horseradish with beef. The plaants can spread rapidly in good conditions so unless you want that plant them in a very large tub on top of the ground or sunken to just below the rim. Good water supply, and plenty of old manure will yield you tender flavousome roots. Mulching thickly will conserve water. TAll the best!

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.
