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

I live in NW Arkansas. I planted bohemian horseradish late this spring in large feed bucket containers. When do I harvest? Can I leave some in the ground or will it freeze since it us above ground in a container?

Can I grow horseradish on the South Coast of KZN

Horseradish is a cool weather plant so plant it in Autumn. Just ensure good drainage and air flow around the plants as the humidity factor in KZN could cause powdery mildew. Please send me some! 063 409 3911.
