Question for my fellow tree experts!

[Hart8]

What would cause(starting last year) every 6 yr old Cedar elm to die?
There's an equal mix of Red oak's,Bradford Pear,Live oak,Crepe myrtle,and Cedar elm.Total of about 80..The Cedar elm's are all dead,or **** near dead.15,20 in all.
My first thought last year was lawn fertilizer...Every tree has it's own little water fountain.Gets water 3 times a week...I know you can over water one as well..Keep in mind they are 6 yrs in the ground..These are the last 2 that are alive.The second will have lost all of it's leaves in a week..Thanks in advance boys.

I'm guessing Dutch elm disease or native elm wilt.

Without seeing them and going just by the watering (bubbles from irrigation system in assuming), I'm going to say fairly confidently that you're WAY OVERWATERING! Irrigation on a in-ground tree that's not in a confined parking lot is only necessary the first growing season in the ground, unless you have pure sand for soil or you are in severe drought conditions. Cedar Elms are the most prolific tree species in Texas and grow from the gulf coast all the way to Big Bend and North to Amarillo. They like to be left alone once established. The Red-Headed Ash Borer is a common invader when the tree is stressed.

Get rid of the Bradford Pear trees. Strong winds will break them up when they get large.

Yoshino cherry trees are a nice replacement.
