For the last 2 years they only flower at the ends of the branches. I have had them for at least 10 years and this never happened before. What can I do?

It's possible some of your buds could have been damaged by cold. Also excess nitrogen can inhibit flowering. If you fertilize your lawn around the plant, this can lead to excess salts and high nitrogen levels. Avoid fertilizing the lawn around your tree.
You can do a soil test to determine if nitrogen is the issue.
If it is an application of phosphorous, like Bone Meal can help boost flowering.
