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

Does anyone have a recipe to make horseradish cream or sauce. I had a very easy recipe made with mayonnaise and have lost it.

Hello Roy, I live between Ballina & Lismore (NSW). Just dug up my horseradish (it's been in our subtropical garden for at least 18 months) and there's almost nothing but slender hairy roots! (But the leafy tops are magnificent!). Google indicates that we should be able to grow it well, but we haven't yet. Any tips, please? Same thing with celeriac. Have you ever tried that in Logan City. (Sometimes we get lost near you - whenever we come up to Ikea. Gonna try and get the correct exit no. showing prominantly). Thanks for your help. Bella

Hello Bella, mine too with slender roots but what I'll be doing shortly is to cut the leaves almost to soil level so that the plant has less above and encourages the root growth instead of all the goodness above. By the way the leaves are also usable. Is yours in a pot or in the ground? I've been growing in both, the potted ones are for anyone who would like to grow their own. Celeriac I haven't grown but celery yes. If you miss the Browns Plains exit no worries if you find your way your way to Logan Central from Ikea , Wembley Road it's just a matter of going all the way to the end and that is crossing over Browns Plains Road then it's just a matter of a left and a left again.

Hi Rob I live in Crestmead and I am wanting to buy fresh horseradish . Would you know of anywhere in Brisbane or surrounding areas I could buy it? Warmest Regards Andrea

Bella I had the same issue with our horseradish which was disappointing. I believe it required a low nitrogen soil, and our home made compost was likely rich in nitrogen as we had great growth with the tomato plants in the same plot... but not fruit. Beetroot was the same. Perhaps next season look for a low-nitrogen fertiliser for better root growth

https://www.diggers.com.au/ have a variegated type. grow horseradish from cuttings or root tops.. buy a plant from farmers market or even supermarket if you can find it. Cut the top off and plant the top. It spreads quite easily if left alone. some nurseries and seed supply places have it but as its not very popular they don't list it on product pages. Suggest you contact them and ask.
