Hi Sandy,

I'm not at all sure what is causing the browning on the leaf margins.  My first guess would be transplant shock. It's going to take the tree some time to replace all the fine roots and get itself established.  You might contact Bert Cregg (<personal data hidden>).  He is a woody plant physiologist and may have some other ideas. I know I planted a chestnut tree on my property in Clinton County.  That Clinton County clay was not good - chestnuts like sandy soil.  My tree declined for a couple of years, then died.  Hopefully you have a better site!
