Need help determining if my post oak is dying. I purchased new (spec) home Jan. 2002 in Highland Village (Lewisville/Flowermound area). So I'm not sure how much care was given to an existing 30' post oak while home was constructed. Last year it was fine, but this year several limbs with no foliage. I exposed root flare in Jan. 2004 and have always been organic. No drainage issues. Is this a sign of news to come? Will the sick tree treatment be effective or should I have arborist take a look? Any good/honest organic arborists referrals?
Thanks

You may be up the creek on this one....

Established Post Oaks by and large do not take well to any changes in their living area. Even stuff that would make other trees healthier can mess them up.

Check Howard's main site- there are a number of arborists noted there. http://www.dirtdoctor.com/businesstest.php

This UNT professor has had some luck, but I hear it isn't cheap...

Owen Yost had a column in the Denton Record-Chronicle on the do-it-yourself version of the treatment, but I can't find it online anywhere. I did find this contact info:
Owen Yost writes about landscaping for the Denton Record-Chronicle. He can be reached at 940-382-2099 or 940-383-9655.

Good luck

I am in Highland Village also and am trying to save my Post Oaks. Mine had been fine till last summer when a strange wilting would occur and pretty soon a whole limb would be taken. It appears to be killing several post oaks in my neighbors yard. This year I thought things were better, but I am again seeing some leaves shriveling and smaller, lower brances dying.

I have stopped developing turf near my post oaks. We are substituting ground covers such as vincas. I am using the Sick Tree Treatment...have no idea whether it is effective on Post Oaks. Also, in a non-organic way, my trees have been sprayed for borers 3 times this last year (Howard please don't delete my post). Several have also been "injected" by the local arborist. Some people say this is effective and some insist it is not.
However, all of the injected trees are still alive.

I realize that the native post oaks, which I love, are the most unforgiving of trees, tolerating zero root disturbance. I am placing Bur Oaks in my front yard as a substitute. But it is frustrating that so little specific information exists on our beautiful post oaks, and no two "experts" seem to agree on the best course of treatment for them.

If you have Adobe Reader, I suggest the following article on the Internet...

Hope you can copy and paste the address...
