John, just looked up the net for growing turmeric and noted your comment on horseradish. Absolutely love the stuff but was unaware I could grow it. I would love to be able to get some from you and am willing to pay for it and its postage too if you have any left. Thank You Val

tasting store bought horseradish and reflecting how mild it is, how is it that (imitation) wasabi which is also made up of horseradish is so pungent.

Store bought horseradish cream contains less than 10% horseradish (this may vary) and contains vegetable oil, milk, etc which would tone down the bite. As real wasabi is expensive a lot of wasabi paste is boosted with mustard seed flour. This may also help explain the variation.

I live in Darwin and would like to try and grow horseradish here. Hearing it likes frosts is it worth a try?

Horseradish would normally be harvested in the winter when it is dormant but there is no reason why you couldn't dig down beside the plant and raid a few root pieces. the plant is almost indestructable and any small pieces of root left in the ground will grow. keep the manure, water and mulch up for good quality roots. trust this helps.
