Joe !!!!! ...

you have a new babe.. what in the heck are you worrying about the trees for??????

up here in my neck of MI .... 6 weeks without a trace of water... and 2 of the weeks near 100 ....

leaves are dropping off the following: red bud, birch, chestnut, oak, poplar, lilac, mock orange .. etc ...

very simply .... WHAT CAN YOU DO ABOUT IT???? .. and forget about the neighbors... their grass is always greener ....

now get your priorities straight... go snuggle the poop machine and forget about your trees ... they have survived in nature.. in drought.. for millions of years.. they can handle it.. and if they cant .. you have better things to do .... now go bath stinkee...

have a great day .. and congrats on the important thing...

I know that Pin Oaks naturally occur along riverbanks and in flood plains. So they prefer moist soil, however, that being said, most flood plain species are very drought tolerant. Typical floodplains have wide fluctuations in moisture levels, from submerged to very dry... It could be drought.

However Pin Oaks are very susceptible to chlorosis. They need acidic soil, else they get iron deficient.

A couple links for you.

You might be on to something there, my lawn was originally a 4.2 pH and I've been trying to slowly raise the pH to improve it for the actual turf.

But once again, the "control tree" in the back field is going through the same thing and it's much too far away to be effected by the lime I put down.

Pictures to follow, wife is going to upload them for me.

Sounds to me like Chlorosis, which pin oaks are very susceptible too. A pin oak loves a very acidic soil 3.7 to 4.5 if the soil is too high in ph the tree stops picking up nutriants from the soil and after a year or two dies. See the link to one of the other forums on this site for some solutions to this problem.

Here is a link that might be useful: adding acid to lower the soil ph

Every time I hear Pin oak and the poster is east of the Appalachians I think Chlorosis. Amirite?
