Horseradish is a hardy perennial that forms a rosette of long leaves. The 30 or more strains in cultivation include Bohemian, Swiss and Sass, and almost all of them are sterile. Below ground, the plant forms a taproot that expands in diameter in the second and third year.


This plant requires a sunny position and a well dug soil enriched with rotted compost. In spring plant pencil thin sections of lateral roots horizontally, or up to an angle of 30° from the horizontal. Cover with soil and firm down. Do not let the plant dry out otherwise the roots will become bitter.

Dig up horseradish roots and use them fresh at any time in the second and third year; they are at their peak in flavour after the first frost. Store clean roots in sealed plastic bags in the fridge for up to 2 months.

Young horseradish leaves can be eaten as a vegetable, but the root is the part most often used. Peel and grate it as needed, as it loses its pungency soon after grating or when heated. To make a simple condiment mix 250mls grated horseradish, 125mls white wine vinegar and 1/4 teaspoon salt. Store in a lidded jar in the fridge. Use this with beef, fresh or smoked fish.

    1. As soon as I get some horseradish I am going to make my own, as the commercial ones have too many E numbers etc. 🙂

  1. Like Roger, I like my horseradish sauce with cream. It´s such a great plant but I´ve never seen it fresh here so my mum males me deliveries when she visits!

  2. Great post on horseradish, I love it and I grow some in a pot (watch out when planting it out in your garden, it will spread like hell). A variation would be to grate some apple into your horseradish with fresh cream, heavenly!

  3. I never thought I’d like horseradish, maybe because I didn’t care for the name lol. But once I had it in remoulade sauce, I was hooked. I love it and I really enjoyed reading about it

I would ♥ to hear from you (comments will be visible when I reply)
