Will container growing horseradish survive winter outside?
I live in Muskoka, Ontario, Canada. If I put my horseradish in containers this fall will it survive our winter?

Your average lowest temperature is -10.5 degrees Celsius (13.1 degrees Fahrenheit). Horseradish is hardy to zone 3 or about -40 degrees F. So it looks like you could grow it in a container. I would still cover it with hay or mulch during January at least.
