I’ve got an apple leaf problem on my new Karmijn de Sonnaville. Leaf clusters are wilting, then drying up. There doesn’t seem to be insect damage that I can see. Instead, there are these areas of discoloration at the very edge of the leaf where it connects back to the plant. I have no idea what is going on. It doesn’t seem to be mildew, and the problem doesn’t really spread far. I don’t think it’s the soil, as I’m using a 5-1-1 mix that I made myself with some added lime (I don’t remember if it was pellet limestone or crushed limestone in that pot).
Aak! The first photo seems to have the telltale droplet of amber ooze that is indicative of fire blight. Trim the leaf bunches 6" back into healthy wood, and stay alert for further strikes.

Kevin, I’m not seeing the droplet of ooze you mention- help me find it, please?
You have to think FB when apples wilt. I don’t see ooze, the shepherds crook, or black leaves. Not yet anyway. But I’d still place my money on FB, sadly.
I’ve got CAR, but this looks nothing like that. I’ll take a look at fire blight symptoms and examine more closely tomorrow morning. I wondered if it might be fire blight, but the damage didn’t really look like the pictures I got on an internet search.
It’s a brand new tree from Raintree, so there isn’t all that much to try to prune away for control.
On the leaf stem about 1cm above the brown patch were the leaf connects to the stem.
Thanks- I think I see it now.
Hmm, does it affect blackberries? Because the symptoms on my blackberry that lost all it’s new growth leaves were pretty similar.
Well, I went back and removed every leaf with damage. Which was probably 75% of them, and cut back the bits where every leaf in a cluster was damaged. One branch, when cut back, looked kind of orangish instead of a health green. I cut that back farther until the cut showed a color more like what I would expect.
I think I see a canker, but it might have been a discoloration from a raindrop since it was about to rain. I’ll check tomorrow.
