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

Be very careful when planting horseradish as it is invasive, confine it to a container.

Hi Keith, Like you, I am also keen to get some horse radish plants as the stuff you can buy here is only the creamed sort and a bit bland. Did you have any luck finding a source?

Search for some seed selling companies on the internet in NZ.
