30 years ago we planted 3 Sugar Maples in the yard. They have always been vigorous and healthy. Usually /Sugar Maples grow leaves as big as your hand which turn brilliant red and orange in the fall. These did that at first but have gradually developed smaller leaves that have less color. This year they just turned yellow/brown and fell.

Sure the easy answer is climate change but these trees do well in Ohio and Virginia and many other places.

And I'm not buying 'the pandemic' either.
