leaf scorch on maple

[RGus]

Unfortunatly I dont have any pics of the tree itself, but I hope I can descibe this enough for some feedback.

So here is the problem. The tree is a sugar maple, about 20ft tall, and 5"DBH. The majority of the leaves have some leaf scorch on them. One of the major causes of leaf scorch is due to high temps, wind, and low moisture. Well if any of you are in Minnesota you know that we havent had many really warm days, and it rained almost everyday in May and so far June.

The tree is in the backyard, so it is not close to any warm reflective sidewalks or drives, and therefore it also wouldnt be salt damage. There hadnt been any recent excavation of the soil, or any damage to the roots.

My question is what caused the leaf scorch, or may it be something totally different?

Any suggestions would help. If you need some more info I will try to help out as much as I can.
Thanks

Maybe too saturated, and wilting?

Not seeing the tree this is just a guess. But here in Michigan we have had about the same weather. Anthracnose is hitting the maples and sycamores. In some areas it looks like fall with all the leaves on the ground.

What about the rest of Schabel's 10 S's?

Vert wilt, Anthracnose..... Any others?


Keep up the good work Ryan!

I am pretty sure it isnt anthracnose. I looked it up and anthracnose has necrosis occuring in random spots on the leaf. Where this tree has it only occuring on the tips of the leaves, and no where else.

Zac, I acctually was thinking about the 10 S's when looking at this tree. At least the ones I could remember.

Species: Sugar maple
Size: immature, 20"
Spread within: It occurs on the whole tree
Spread between: There were other maples (silver) but not affected
Signs & Symptoms: necrosis on the tips of the leaves

Thats all I can remember of the 10 S's I will have to get out my old notes and take a look.

Thanks guys.

Site (you covered this above), sex, season, what's the other one?

Rgus,
If you weren't in Mn., I'd guess with near certainty that you have a tree planted too deeply... stem girdling roots and all. If there discernible flare at the soil line?
If the tree goes into the ground like a utility pole, and if it's a maple, diagnosis is a gimme.

Is the leaf damage down the veins or between them? Should help to solve the anthracnose versus scorch debate...
