The Q&A Archives: Japanese Red Maple Tree

Question: I planted a 6 ft. Japanese Red Maple tree last Dec. and it has been doing very well and looking fabulous. I have recently noticed some of the leaves look like they are turning slightly green and some of the leaves have tiny holes and are not as red as they were. I can't find any definite information on what this might be and how to treat it. I would appreciate any advice you may have.

Answer: For the type of Japanese Maple you have, it may be normal to change from red to green in the summer & then turn back to red in the fall, especially if it is in too much shade. That's the way my "Bloodgood" Japanese Maple was when I got it last year. But this year, when I moved it to an area where it got a bit more sunlight, it's now a dark red-purple! (I'm expecting it to turn a brighter red color this fall). As long as the tree looks otherwise healthy, green leaves will change back to red in the fall. Tiny holes are caused by insect feeding but generally won't affect the health of your tree. It's difficult to control insects in the canopy of the tree and a little damage shouldn't cause too much concern. Good luck with your landscape!
