I'm trying to help someone figure out whether her ornamental pear tree is going to survive. It was just planted 3 weeks to a month ago. The meristems are producing healthy leaves, however the older foliage's leaf margin is drying out and the center of the leaf has an oblong orange/red color to it. I can't say whether it's fatal to the tree or not. It looked to be effecting 30-40% of it. Thank you!
