  • Harvest in 16-24 weeks. Some improvement in flavour if left till after frost..
  • 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

Strong, spicy flavour traditionally used with roast beef.

I’ve just acquired some in Southland. I’ll grow it up this season and can pass some root on to you in autumn/winter if you’d like? If you send me your email address, I can let you know when I harvest it.

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?

New Zealand has strict quarantine laws when it comes to importing fruit, herbs and vegetables.I am sure they would not let it come in.

Hi, I would love to plant horseradish in my Waihi garden. Is there anyone in the area who can spare a piece of root? Cheers, Vera
