Hi all, I bought my horseradish from a fruit and vegetable shop which order it for me from Freni & Doria PTY LTD but I assume you can buy it directly from them www.melbournemarkets.com.au/trader/freni-doria-pty-ltd/ Cheers Anca

Hi. You can buy little seedlings at Buleen art and garden centre. I just planted my first ones and they were eaten by slugs so Be careful.

My guess would be you have picked it too early or your soil is a bit poor. Read the notes here about growing it. Or google how to grow it.

Does horseradish produce seeds. If, when and how to recognise them. Where to buy in Australia the horseradish seeds? Regards Chris

Hi Chris, It's easy to grow from a piece of root , you just have to plant it and it takes care of itself. It's best not to plant in the garden as it is invasive.I have it growing in a large pot and can send you a piece if you like . Cheers Clare
