Bradford Pear Tree Won't Bloom

I live in the southeast part of North Carolina. I have a Bradford pear tree in my front yard. It's about 12-14 ft tall. Its shape is beautiful, but it never blooms when the rest of the Bradford pear trees bloom in our area. If it blooms at all, it doesn't until all the others are done blooming and sprouting green leaves. I've tried adding fertilizer and Miracle Gro soil, but nothing helps. Can anyone tell me what I might be doing wrong?
