My tree didn't bloom no flowers this spring and now we're in summer.

How old is the tree - is this a new planting? Did it bloom last year?
Did a cold snap occur after budding? If so, this may have killed the buds resulting in no blooms.
Did you prune when the buds were set?
Other possibilities include lack of pollination or excessive nitrogen in the soil (did you fertilize?)
