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

  • 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

My late husband was the gardener & I was wondering when do I actually harvest horseradish
13 Jan 15, Roy (Australia - sub-tropical climate)
Margaret, I haven't found the perfect time, the size of the leaves don't tell me anything. Last week I did use some, just scraping away surrounding soil and seeing the thickness of the root helped, the root was fairly thick, about the same as two fingers plus a little more. Getting it out is the hard part, the roots go down a long way so I cut the amount I needed and replaced the soil. Be careful if you do this because the root is very strong, a serrated knife worked o.k

Viera, don't buy it I have plenty, am in Logan City. I'll have to find out if I can give out my phone number or through Gardenate's Email address ( Roy, you can give your phone or email in a comment but NB this is a public site and we have no control over who reads the comments - Liz )

Thank you Liz, I have seen someone else's Email address so I'll give mine which is [email protected] maybe someone else in this part of Queensland might also like some horseradish.
