I have about 15 - 30 year old oaks in my yard. I'm far from an expert, but I'm told they are live oaks. Recently I've done some construction nearby and "shocked" one of the trees. All of the leaves have browned, but not fallen. There are 2 of them side by side, no more than 6 feet apart. I think it's safe to say their root systems share the same space. One of the trees leaves browned, but it dropped all of the leaves. The other hasn't dropped them, and it's starting to lose some bark. I've contacted an arborist, but the treatment for the tree is going to be over 700 dollars, which I just can't afford right now. I also contacted my local fertilizer dealer, and they made reccomendation on several products to use. I just don't know if the tree is too far gone. It's been about 2 months since the leaves started browning. I've attached some pictures. Need some help, I don't want to lose the trees
