Hi Liora, We just moved to Kingscliff from Alice Springs, NT and I would like to grow my own horseradish. May I ask, where did you source your plant/root from? Alternatively, do you have a piece I could purchase? Thanks, Trish

Horseradish should grow well in SE Qld but would probably still be dormant in the winter, particularly in cooler areas such as Toowoomba.

Hi Trudy. I bought my horseradish root through ebay - a place in the Blue Mountains (NSW) - it's grown magnificently but it did take a while to establish.

For many years I bought a brand named Edal or perhaps Edel but so long since I've been able to find it where I live on the Central Coast. When available it was in the refrigerated section of the supermarket. So good you can eat it from the jar.

Eskal - the best but really hard to get in rural oz.

My mother would grate approximagely equal quantity of raw horseradish and cooked beetroot which we would have with almost any kind of meat, espacially deli kind. If kept in fridge it can last for a while but we would use it up quickly.

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
