At the end of the season I made the mistake of not dividing the plant. The tubers had grown into several plants and should have been divided. It grew itself to death (sounds silly, I know) the following year. Unless dahlias are divided, regardless of the growing zone, the ball of tubers can't get sufficient nutrients to survive. People will notice fewer and fewer blooms and attribute it to something other than the true cause - they do need to divide dahlias.
