What could it be? I’ve removed a couple of cross over branches because the tree is only a year old. The area can be quite windy and some day have been very chilly. Live close to the beach tree is in back yard. It has a beautiful flower just this week hopeful more to come. Thanks
If this damage was noticed after your pruning, and the shears were not cleaned before trimming, then it is likely that the pruning has brought about an infection.
Fungicides will be necessary. This article will help:

I have 2 orchid tree both 6 yrs old but never had flowers. Why is this happening & what is the remedy.
I took a look at the other answer. It seems that the links take you to places that show the requirements of the tree. If they are met, then flower drop will not occur. I took the liberty of extracting all of the very useful information.
It boils down to pH, soil nutrients, moisture level, temperature, and nutrient content of soils.
You will need to test your soils.

We are in zone 9 and the tree is in full sun. What does this tree need to bloom?
This comes down to two things: Soil nutrient content, and watering habits.
The first thing to consider will be how much nitrogen is in your soil. Too much nitrogen will halt flowering in legumes, which this tree is. A soil test will confirm:

Next to consider will be watering habit. During the growing season, you can water often without worry. In winter, flowering will be triggered by dry periods followed by wet periods. Testing soil moisture may be necessary:

I topped it a few years ago. Since then it only blooms at bottom. Is there anything I can do to fix it? It looks healthy
It is still a little early in the year for good blooming, but I suspect there to be too much nitrogen in the soil. Technically, these are legumes, and will draw their own nitrogen from the atmosphere, fixing it into the soil.
This can be offset with phosphorus and potassium fertilizers.
Another thing is that they will prefer to flower after a dry spell, then a wet spell. It may be that it is at the mercy of the weather.
