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

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.

I have only made a smooth, semi creamy sauce so can't help you with a recipes. Try Googling 'horseradish sauce recipes', you will find plenty. Trust this helps.

Is it best grown in full sun or shade
08 Feb 17, John (Australia - temperate climate)
Horseradish will grow in full sun or part shade. It is a very hrdy plant and will spread rapidly in good conditions. To contain it you can plant it in a large planter pot and sink the pot into the ground. Horseradish loves damp conditions and in this situation will produce the best roots but will still do well with less water. Trust this helps

Horse radish would normally be harvested when it is dormant but there's no reason why you couldn't dig down beside the plant an bandicoot a few roots for your favourite source! Horseradish is very hardy and any piece left in the ground will grow. Trust this helps.

When should I harvest my horseradish ? Very leafy i its own raised bed and looking real healthy

Horseradish would normally be harvested in the winter when it is dormant but there is no reason why you couldn't dig down beside the plant and raid a few root pieces. the plant is almost indestructable and any small pieces of root left in the ground will grow. keep the manure, water and mulch up for good quality roots. trust this helps.
