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

I have horseradish it’s easy to grow. I live up in northern Minnesota. By accident I have three patches growing. Remember to get rid of weeds around the horseradish. Also you shouldn’t dig up the roots until September through April. Months with a R in them. Try going where they sell plants and ask if they have horseradish roots.
