What is considered a good survival rate of hosta? Is there a difference between ground bed survival and raised bed survival for hosta? I know that winter conditions can effect this outcome but what about the growing location itself? One might add to those two: survival by driveways, streets, beside buildings, and out in the open as well.
As I raise Hosta in a raised bed against a building I found that between the 2012 to 2013 seasons I had a survival rate of 56% (from 18 to 10) which by anyoneÃ¯Â¿Â½s standards for hosta is bad if not questionable. I have guesses as to what happened but they are not discussable until I see what happens between 2013 - 2014 seasons. My 2013 - 2014 prediction for survival is 86% and obviously that has yet to be seen.
One person has suggested a 90% rate is reasonable thumbnail for survival. What do others think?
