Those temperature swings you are experiencing are pretty common in the front 
range of Colorado and high elevation New Mexico.  There isn't much I know of 
to do that is feasible for a long period of time after planting.  Before 
planting it is about location either near water or in areas that are shaded 
through March or so, and also about plant and variety choice.  Apricots and 
hardy Kiwi's sweet cherries and Japanese plums are more challenging due to a 
general tendency toward early bloom. Mulberry jujube and american persimmon 
generally don't have bloom issues, they are consistently later, as for many 
of the rest it is variety choice go for the high chill late bloomers or ones 
with frost tolerant flowers.
