This combination mixed with sour cream also makes a fantastic dip!

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

Are places unusually hot in summer, such as Phoenix, AZ area, too hot for horseradish to grow, assuming it's being watered throughout the summer months?

It's not too hot, but in place like Nul Arbor plain in Aus., better to plant in Winter, & be sure to water.

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
