I have several maple trees dying, we have already had one taken out. I had the remaining 2 treated with iron supplements last August, they seemed to get worse after that. While walking around our neighborhood I have seen several other trees of the same type in the same state. EDIT ( this is Colorado )

Looks like textbook chlorosis to me. What type of treatment did you receive? Do you know what product and process? Sometimes iron treatments just don’t work because of the tree is too far gone before it’s treated. I’m saying that that is the case here bevause I would be curious to know more
The maple trees appear to have a manganese deficiency. One sign is when the veins of the leaves are darker. I haven’t seen this deficiency kill a maple tree. The maple trees may be planted too deep or have girdling roots.
Chlorosis isn’t automatically an iron deficiency. Could be iron, manganese, zinc, copper, nickel, boron, etc.
Treating without confirming what the deficiency is through tissue analysis is braindead business practice.
Your trees look like that because they are not adapted to the soil or climate. You will never have them fully green and red fall color-y. They are not recommended for the [Front Range](https://planttalk.colostate.edu/wp-content/uploads/2024/04/2024-Front-Range-Tree-List.pdf).
Typical question for the tree subs.
This seems to be quite natural in my opinion. I’m in California, mind I’m no expert. I’ve taken a notice to a shift in seasonal climate changes throughout the last few years, and there has been a shift in the start and end of the different seasons throughout the year. I’ve deduced that this may be from the massive tsunamis that occurred some years ago I’m other continents, that have shifted the rotation of the earth by about .2 degrees every year, but it’s happened like twice. Those events seem to have shifted the seasons we experience by about a month later in the year, as well as shifted the climate we experience, so we get weather patterns more consistent with slightly southern regions.
Sorry if this isn’t really an answer for you, but saying as my maples are experiencing the same, as well as additional seeding, this may be an accurate explanation for you and help ease your mind on it. I say your trees are quite healthy, I just wouldn’t do any pruning. Again this seems natural, i figure its because the winter months are weirdly coming early, despite what I said about months being late. Im trying to figure out what coorelations I can make, but thats all of what I know for now. Keep it up! They look good by the way 🙂
