Been in ground one year
It is good to do light pruning from an early age to insure good structural integrity for the maturing tree. But it is not good to prune excessively or without a good reason.

I live in Oakland, CA. I purchased this from a reputable nursery three years ago. It's planted in a well-drained moderate hillside facing mostly west. It's the hottest part of the house. The first year it did okay. I watered it moderately. It bloomed moderately. The second year a lot of the bark turned brown and it bloomed less. I watered it less. The same nursery told me to cut the dead off above the green part. This year it only bloomed a tiny bit (shown) and you can see how the bark has continued to deteriorate. What could be wrong?Need help with a Palo Verde tree
This seems to be an infection that has, not yet, been resolved. They are very drought tolerant, but will not tolerate wet soils. This leads to infection, somewhat quickly.
I would treat with a fungicide, and prune out any growth that is completely dead.
Be sure to only water during times of severe drought, or at the very least, make sure that the soil dries out thoroughly down to about 4 or 5 inches between waterings.
Here are some articles that will help:

The tree is very healthy, blooming width wise and full of blooms. It just won't grow taller.
This could indicate that something isn't quite right about their environment. Unfortunately, your photos did not come through, and There isn't much information on the environmental conditions surrounding the tree.
In the meantime, this article will help you to know what kind of care these trees require:

Hello. I live in Encino, CaliforniaI. I have a beautiful Palo Verda tree in the center of my front yard, that I planted when I purchased my home five and a half years ago. It was then about seven feet tall. Today it’s around 40 feet tall and 32” in diameter at the base. I love it. It gives off a unbelievable amounts of beautiful yellow flowers that the bees and hummingbirds love. (see Photo) Unfortunately, For a couple of years now It’s been bleeding sap in several locations at its base going up to about six feet. (Photos attached) I’m very concerned about its future. I’ve asked my local nursery expert. And at their advise I sprayed for worms also applied systemic Bayer Tree & Scrub Protect & feed and Bayer Complete Insect killer. Plus numerous organic products. All with little to no results. What would you advise? Thank you, Sam
I would continue the systemic, according to the instructions. This will be your best defense against borers that are already inside the tree.

If it is tree borers, it is very hard to kill them because they are inside the tree doing extensive damage. It is usually best to replace the tree.
