  • Compatible with (can grow beside): Best kept separate
  • Horseradish leaf

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

Culinary hints - cooking and eating Horseradish

Hi, I bought my horseradish plant as a baby from Bunnings for about $3.50. Second season now and I have about 7 plants in the one spot and it's GROWING... Wish I had have read that it takes over BEFORE I planted it in the ground!
