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.

As regards horseradish, I have grown this plant, but in my opinion, it would be a mistake to think you can plant it in April and harvest in 24 weeks time and have a useful root. For Horseradish to get a nice thick root, with the distinct pungent flavour, it takes a good two years per plant. And do not underestimate how much work it is to clean the dirt out before shredding the root. It is a wonderful taste and worth the hard work, but in my experience, you need to set up a dedicated bed, plant the roots and then prepare to wait a few years to get the cycle of having a constant supply of usable nice thick roots. The roots grow very deep into the soil (a good 2-3+ feet) so it is a good idea to leave some room around each group of plants, because you need to dig quite a wide hole to get the roots out. We always harvest at Easter here in Sydney. Bon apetit.
