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

Work out your climate from the BLUE TAB Climate Zones at the top of the page. Go to the Horse Radish page, set the climate zone to your climate - TROPICAL. The recommended planting time is in the planting calendar.

I have plenty of horse radish, but I live in United States and I don’t know if I can send the roots over seas. If I can mail the roots I will. Does anyone know?
