Quoted from that article:
"there are 3 stages in the acclimation process. The first actually 
started when shoot growth stopped in early summer, and the tree began to 
store carbohydrates in branches, roots and fruit buds. So even, at this 
point, trees can tolerate about -21°C"

So are they saying the temperatures in July or August could suddenly 
fall to about -5 F and the trees could survive that? That's pretty 
unbelievable.

I'm also curious, but not really worried, about how my trees will do 
considering that November was warm and actually sunny but then last week 
we went down to -25F one night.
