I have a very old (possible 100 yr old) native Texas Pecan tree. Within the past 4 years it has been hit twice by lightning. Several strips of bark are begining to fall and one large open wound is decaying. I have sprayed for insects, fungus, fertilized, applied tar, concrete, ect... I still can't stop the decay? This is a great pecan and shade tree? Had a large crow this year? Please help..

I can only make a few general comments without more info., however; first, stop aggressive repair/control tactics. Trees, specificly older trees are much happier stabilizing and out-growing injury than when we try to help. Actually you cannot stop the advance of decay following wounding and certain treatments (concrete) are damaging. At this point do two things. First, pay attention to cultural maintenance, water in periods of drought, fertilize if necessary ONLY after soil test and then modestly, etc. Also, discuss the structual intergity of the tree with a professional. Second, you may wish to investigate lightening protection. Expensive, but it is effective when installed properly. There are written standards regarding these systems. Let me know how you make out at my E-mail address. Good Luck
