Question From: Annville, Pennsylvania, United States
Q: My katsura tree leaves never change colors stay green! What's wrong?
That's a good question Joan and one I can't answer as I am not a certified arborist, I suggest you contact the folks at the Morris Arboretum of the University of Pennsylvania. They have lots of folks on staff that specialize in trees. Here's a link to their website. http://www.business-services.upenn.edu/arboretum/collection_katsuratree.shtml.
