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. You can buy little seedlings at Buleen art and garden centre. I just planted my first ones and they were eaten by slugs so Be careful.

Hi, just dug up my horseradish and it is really spindall. What have I done wrong?

My guess would be you have picked it too early or your soil is a bit poor. Read the notes here about growing it. Or google how to grow it.
