I bought the Horseradish cuttings from eBay. They were sent from Springvale in Melbourne. Fast and easy and they all took off

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.

You just need ordinary soil. Keep it watered, a wooden box will dry out quickly. You cannot grow horseradish without leaves.
