Help with dying trees...!

We live in Katy, TX, far west Houston and have several Japanese blueberry trees and one Japanese plum that are dying and we don't know why. The earliest we can get somebody here to take a look is next week, so I thought I'd post here to get some opinions. Here are the pics:







Now it's been pretty hot here lately, and we've had probably an average amount of rain, and the sprinklers run a couple of times a week, so they should be nicely watered. Does anyone have any idea what could be wrong?
I don't know why the pics show up sideways, they don't on direct link...

Thanks, and I'll hang up and listen

1. Beyond my meager gardening skills BUT--

surely you could send pixs to an agriculture school in Texas. Looks like scale to me - but, again, I kill everything I plant.

3. I think that is lichen, not scale. I also see some moss.

Could you be over-watering? Or are they in a very shady spot?

4. They get a lot of sun

We could be over watering; I turned the sprinklers on from 3x a week to 5x because it's been so hot and the grass is dying. I'll turn them back down and see how that goes.
thanks!

6. Although this is out of the area I work in I would guess that your plum tree has borer

Look to see if you can see patches of "gummy stuff" that is coming out of the bark.

If > the 60 % of the tree's twigs snap and have no green to them (peal back the bark
and look for green) then cut the tree down and plant a native tree.

The lichens that you have shown here have NOTHING TO DO WITH THE TREE'S HEALTH.

Also @ the base of the tree you might have a problem with the tree's graft.
