Hi!
My friend's JM isn't looking the best. We didn't see any evidence of pests. The damage is on the leaves. Don't see anything on the trunk. Can somebody tell me what's wrong with it and what needs to be done to help it. I tried searching online and I'm just not sure.
Thanks!
Emily

I'm hardly an expert on JM's but it looks like heat damage and/or lack of water. Has it been exceptionally hot where you are ?
I've seen a lot of them around here with the same damage recently, and it's been very hot here.
For the most part, the Philly area has had a mild summer (mostly in the mid 80s or so). This past week it's been warmer (in the 90s). We've had A LOT of rain this spring and summer.
From what I understand this JM gets a fair amount of sun. My friend just emailed me: it's an acer palmatum dissectum.
I would suggest the Japanese Maple forum for help on this. Most do not like full sun.
Thanks. I did try the JM forum. No one responded so I thought I'd try here.
We have a 'crimson queen' jm we moved from our old house down to the country with us as it was such an expensive tree and it has grown nicely here. We did have it shaded by several small deciduous trees that DH removed in order to put in a pond. I was scared it would not do well, however, it has done just fine and it is now about 13 yrs. old. I make sure it is well tended though. It will be one of the major features when he finishes the pond. As a rule, they are considered understory trees. Maybe your friend's could use a nice helping of compost/manure and kept well mulched.
It doesn't look so bad - just some sun damage I think. Towards the mid-end summer --if it is in the sun -- this is unavoidable (at least in my experience.) In the spring --it pops back nice and pretty.
Looks like mine in TX. It looks good in the spring but by July the ends are like yours...sun scorched. Mine recovers and it doesn't seem to be hurt by the edge damaged leaves. Mine is in part shade but gets a blast of morning sun which in TX apparently is more than it wants. I have had this tree for 3 years and it leafs out nicely each spring, flowers and is growing well.

looks like it may have some sort of powdery fungas on it. I would spray it with a spray bottle mixed with a little olive oil and a few drops of dish liquid. Then what won't hurt is to add ebson salt to the soil at the root, may be a deficiancy in the soil. Good luck I've been doctoring stuff in my yard that for around three years was in a drought but looking better this year due to much needed rain.
