Autumn blaze maple dying???

5 years ago

last modified: 5 years ago

I planted two autumn blaze maple trees in my front lawn two summers ago. They both were doing great last summer, but this summer I noticed that the one to the south turned red very quickly and the leaves are very sparse in comparison to the other tree. I also noticed that the bark is splitting in several areas. Is this a sign of the tree dying? Is there anything I can do to help it?

The other tree looks very healthy. The new growth on many maples is very colorful. The baby leaves at the branch tips will start out shades of orange and red and then turn green as the leaves grow to full size.

Sorry but I would say the first tree shown is a complete loss at this point. It appears all the bark has been removed by something below the cracked portion, with this removal of the bark being the likely reason for the collapsing and discoloration of the foliage.

Not saying the mulching is what killed the first one but if you have the bark chunks touching the stem of the second one also you should pull those back away from it.

Maybe the area will look better with one large shade tree anyway, as we can see from the shapes of these shown here when 50 ft. tall (and not crowded) this variety is not, in fact going to be only 25 ft. wide:

And Freeman maple is a crossing of red and silver maples, both large-growing trees. There is every reason to expect any given planting of these to grow over 60 ft tall. With proportionate spreads, except for certain much planted abnormally narrow growing named selections (of which we can see at the above page 'Celzam' is not an example).

Looks like it has a health problem. Overall color is pale, may need nitrogen fertilization. Branches with brownish leaves may actually be dying. Might have to enlist help of Illinois Cooperative Extension to find out what specifically is going on.

Yes, we are Sunset 3B here.... The sunshine on most days and temps in summer is the reason so much agriculture grows successfully here. Of course, they irrigate. I am surprised Wenatchee is the same zone as us, but I guess it doesn't take into account the amount of snowfall they get (They are probably the -15f extreme.. we are more like -5f.) RE: the suitability of the trees I listed, The Thornless Honeylocust seems to thrive here, it does well in alkaline soil and is drought tolerant. As a prairie tree, it thrives in full sun. I have noticed many honeylocusts in yards that do not irrigate, growing just fine... The list of negatives of the tree is pretty short, and it seems very adaptable to our conditions. Linden -- RE: irrigating, I don't know. We will have some lawn on the property, so a tree/trees in that area would get more water. Linden tolerates alkaline soil and has small leaves... Thus, it seemed to be an *option.* ash -- I still have to go to our local extension office.. I will ask them about borers here. Ash also tolerates alkaline soil and was another option for my lawn area. If the borers are that bad here, I won't consider it.

It sounds like they are suffering in the heat and drought. They may recover and do better once established. Make sure the soil ball is staying moist from your hose watering. Stick your finger in there.

nurseryman33, thanks for reviewing and responding to my post. I have given the tree a closer inspection. The dying leaves have now spread to about four branches. The branches are not physically damaged. The buds look good, where the leaves still look good but out toward the end of each branch, where the leaves are dying, the buds are dying too. I noticed that on both dying leaves and healthy ones, there are very tiny little bugs/mites. They are black and hard to even see (smaller than bits of pepper). I now wonder if I have some type of insect infestation. I will do more internet research. Your response is appreciated, thanks. This post was edited by Redwing2 on Sun, Sep 1, 13 at 10:21

The photo was a little deceiving. The bark below was wet. But it does look like something is pushing the bark out on the bottom.

probably a goner .... all you can do is wait and see ... even if it hangs on.. it isnt going to get good enough to thrive for a long time ...

if somehow you have a 2 year warranty.. talk to your seller ...

was it ball and burlap or potted ???? ..

i suspect it was heavily damaged prior to you buying it.. but the damage under the bark didnt start to show until now.. i call that tree time ... but this is mere navel gazing.. i dont know how you will figure it out ...

if the other has thrived .. then i would presume you did everything about right with one ... so that only leaves the above theory ... regarding the other ...

the only clue we might find out.. is where is the root flare .... see if you can excavate and find out .... maybe it sunk after planting ...

Looks like a wicked case of sun scald to me. I've seen this on hundreds of young maples. The wound begins to look worse and worse once summer arrives and the injured bark dries out and recedes. Did you have the trunks wrapped or covered during this last winter? The shadow of the tree on the ground shows that side of the trunk is facing a southerly direction.

These two were potted when we got them. Unfortunately there is no warranty.

Once the injured bark dries out and recedes do the trees normally survive?

I did pull the nuggets away from the base and noticed that the bottom of the trunk is much skinnier than where the bark is splitting.

Most trees that suffer sun scald do survive it as long as the injury doesn't go more than halfway around the tree trunk. Then the biggest threat during healing is usually storm winds snapping the tree off at the wound. Unfortunately, it looks like the injury is severe enough that the tree won't likely recover. The sickly look of the leaves is what is most concerning. I suspect the tree may wilt soon from being nearly girdled if not completely. You can wait and see what it does but I'd be prepared to replace the tree in the fall or spring if you really want a tree in that spot in the yard.

you have nothing to lose.. by just a waiting.. and watching.. and seeing what happens ... thats how we learn things ....

except that it is out in front of the house.. where it might piss you off every day ... lol ... for me.. lifes too short to be p.o.'d by trees ...

next planting time for trees is fall ... maybe it will die by then.. and solve the problem ...

Should I be concerned about the reddening of the tips of the other tree?
