MN Tree blossoming dates

N.Carlson - April 15, 2012

Over the past 10 years or so I have been taking a photo of the first blossoming of the crab tree in our front yard.  The blossoming appears to be more temperature related than to the amount of available sunlight.  So far no pattern yet.  2012 was a very warm spring 2013 and 2014 were very cold springs.
