Spring of 2015 I bought blueberries in a pot that fruited decent.  I bought these from a box store.  Fall of 2015 I transplanted them into the ground.  They are on the eastern side of a fence.  
 They didn't fruit this year.  I got some flowers but they shriveled up with no juicy treats to be had.
 Did I transplant them at the wrong time?  Do I need to use more  pine mulch?
 I'm in eastern Washington state, zone 5b.
 I want to eat blueberries!  They tasted like candy.  I miss them.
