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!
