Peter,

If your blossoms are at pink, they cna withstand temperatures of  -3C. 
At -3C you will get about 10% loss and at -6 you will get 90% loss.  I have 
a chart posted at 
http://www.theorchardkeeper.com/pdf/Critical_Temperatures_for_Frost_Damage_of_Fruit_Trees.pdf 
that gives you the Critical Temperatures for various types of fruit.  Hope 
this helps!
