Understanding your growing zone is very important because it is a measure of the lowest temperature that a plant can survive, helping you to decide what plants would grow best in your particular climate. Since St. Joseph is in growing zone 5a this means that plants there can survive temperatures as low as 10 to 15 degrees Fahrenheit. Plants chosen for St. Joseph's climate should be chosen with this in mind or plants should be moved inside to keep their core temperature in the right range if necessary.
