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, I would love to find out where in the Hawkes Bay region I can buy a plant or cutting? Having grown up in Sweden / Europe with many traditional dishes containing the wonderfully hot root (grated and mixed in sauces, potato salads etc. .. the list is long) I truly miss the unique flavour ...

Hi Kim. We can probably help depending on the type. I understand some folks call a rather large white tuber HR. We have the type that grows in the ground as a root, extremely hot, dies back in winter and comes away spring. Used for sauces etc. Is this what you want? Paul.

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.

I enjoy eating what we can grow here on our farm. I've been thinking of growing horseradish. I'm in the central MS area. 8b I think but not certain. This will only be growing for our use not looking to grow commercial. What can I do or would you recommend? Thank you
