I am over in Bend today teaching berries crops.
Talk about a rather harsh environment
that they have over here.
Their last frosts can go into June OR LATER,
 then the first frost as early as the end of
August,  Some years 90 growing days
 and on a  good year 120 days.  So the
Willamette valley isn't the only place that there has
weird weather patterns.

I was looking at blueberry bushes that
had frost damage on the tips AND at the
base of the blueberry bushes;  a real burn affect.

We talked a lot about protecting the roots of
strawberries, raspberries and blueberries -
by putting down 4-7 inches of a good
clean hay.  Some winters have a long period
where the soil can freeze down 12 inches plus.
