    That is a bad sign, possible oak wilt. Pull on the brown leaves to see if they come off easy.

    I don't suspect it was a late frost. Did it get hit by lightening? Maybe an insect infestation. See if you can pull of a layer of bark anywhere around the trunk.

    Karl:
    You probaby know that Live Oaks drop their leaves in the spring when the new growth actually pushes the old leaves off. The old leaves form a membrane between the tree twig and the leave itself cutting off the water and nutrients so new growth can occur. Cut a twig about the size of a straw. If the cambia is green and slick, the tree may just be a little slow in pushing off the old leaves. We have similiar stuff in SC, but there are very small buds showing. If the tree is dry and not slick around the woody part between the cambia, then the tree is dying.
    How big is the tree in height.

    I just got off the phone with Karl. I have advised him to Contact Steve Brown his County Extension Agent. I have a lot of respect for Steve and I am willing to travel the extra 50 miles for his seminars, because my own County Agent is a fool. From what Karl said, I have little hope for this tree.

    Ric/Karl: Please post the findings here. I hate to see any tree die from unknow causes. Last year during the drought in TN. We saved all shower/bath water and waterd the trees with it. Everything this year is beautiful, although I've seen a lot of drought damage especially in the lawn in TN.
    Thanks and please follow up.
