It's hard to say why one is blooming and the other is not, but here are some possible reasons:

• Late frosts can damage flower buds in spring.
• Warm temperatures in late fall prevent trees from going dormant, and then freezing temperatures damage the buds.
• Sometimes trees are heavily fertilized in the nursery and forced to flower before their natural time, and so are weakened. If this is the case, you may have to wait another year for your tree to bloom.
