Get a grip will ya?
It's a rainy Sunday afternoon here in Beautiful Southern Ontario.
And my large Maple outback, and the 2 dozen I can see beyond it are just fine!
I'd be more worried about the Emerald Ash Borer than dropping leaves off a maple.
Besides, most maple trees in Southern Ontario are infected with a benign spore that turns the leaves spltchy black/brown, and drop early.
It does not kill the tree, but it looks like crap.
The only way to get rid of it is to burn the leaves, mulching just spreads it.

I guess that would depend on species tolerances. Some just cannot handle heat and some just cannot handle cold. March of 2011 we got hit with a zone 4 winter and we are a zone 8, we lost a ton of stuff, even natives.

I am in the desert southwest, and in the summer I could provide water for northern based trees, like the sugar maple, it is just the heat index that keeps them from thriving. Sorry, they are here, but they do have to be pampered.

First point: You are incredibly patient.

Okay, I havent read your previous thread, so apologies if this is redundant info:

Has there been anything in the past few years that may have disturbed the trees roots? Construction in the immediate vicinity? How close to other trees, structures, or the roads? How tall/old are your maples? Any chance you have a septic system near-by? Have your neighbors done any digging or construction?

When was that well put in and what is its proximity to the trees?

All of these things could be effecting the roots in a way that is stressing the trees. The fact that you say its not happening to other trees in the area makes me think it;s not environmental (at least not primarily), but a problem with the trees.

No problem with the apology as I felt I owed you one anyways for my snarkey reply to your first post.
I have a major problem with people posting whom have not read the entire OP.
It's a hang up of mine I guess, anyways thanks very much for the link and I read it front to back and it does seem to apply here somewhat, The symptoms are correct but we have no construction nor drought here at all.

Our front maple has the yard to itself and our three others share the back yard with a pond and some pretty nice gardens if I say so myself:-).

Again I just cut the lawn yesterday and this morning it was loaded with leaves.

I appreciate your apology and I hope you get mine here too.
Thanks very much for the link and I will keep the uniformed informed here if I can.
Regards, Iwinder

Star for you sir/madam

The "Scorching" your pictures show (when the outer edges curl in and turn brown) is usually a sign the tree is not well. Not dying necessarily, but being restricted by something, likely at the roots. Maybe something underground? Or maybe their outer roots have reached something limiting their further growth (like the road, neighboring properties, etc).

here's a website that talks about it in far greater detail

I look forward to your reply.

How close is the front one to the road/driveway/house, etc? That could effect root growth. How old/tall is the tree?

And the back?


The front tree is in the pictures Des so kindly posted for me, as you can see it is dead center in the yard and has about 60 feet deep by 65 feet wide for space and no trees encroaching on it.

The front tree is about 50 feet tall and if you check the pic you will see we had it cabled to save it from splitting.

The back trees vary, one is only 4 years old and the other two are around 12 years old or so.

Thanks for your interest in this thread,
Regards, Iwinder

Again, as the roots grow, if they run into anything underground that will limit their growth, it could weaken the tree to some degree (not life threatening), and cause the signs of stress you are seeing. It could easily be the pond, nearby roads, etc.

Have you tracked the UV index for your area? The index seems to be very high, very early, this year. I have seen it max out at 11 several days, adding the incoming CME energy might be too much for some plants - and humans. There is a good thread on here by someone who has graphed the UV index, seems to be increasing and this might be the issue.

Has disease been ruled out?
Does the tree[s] seem as full-leafed as in past years?



So far, I not seen anything like that here in SE Michigan.....fingers crossed, though.
As we do have more than a few stressed tress on our block....fewer leaves, smaller leaves...but so far, no drop.

Forgive me if I missed it, but what kind of fertilizer do you use?
Organic or inorganic?

It does make a huge difference.
