My mom moved into a new house and the HOA has planted a number of oak trees along the street. The one in front of her house is definitely struggling. We've started watering it nightly and I put in these deep drip stakes connected to the drip irrigation to help as well.

But the base looks to be in real bad shape and there's these spots on the tree that I'm not sure what's going on. Is this all insect issues that can be treated?

EDIT: This is in DFW, so I'm sure part of it is heat stress. There's a tree two houses down that is 100% brown and dead. Just hoping we can save this one.

Submit this via email ASAP to Neil Sperry's radio/other shows

or to your county extension service office.

Also get advice how to save the rest of them,
what to replant in its stead if a goner. (Chinese Pistache even I can grow EZ)

Only the base of your tree's problems look familiar to me as
The Freeze then
Then Drought in Aggieland
stressed our huge 3-+yo Live Oak so that it got
Hypoxylon canker death sentance

The upper portion malaise & white bubbles are a mystery to this Black Thumb

So sorry, start a search ASAP for someone to gently fell this tree, perhaps divide up the firewood

Not 100% positive, but appears to be sun scald damage to me...
