Dropping leaves

[Philipk]

Hi all
looking for some advice, my Chinese elm seems to be losing some leaves, some have a brown mark on. The tree is kept outside all year round and I live in the south of the Uk, weather is in the 22 degrees C .
I feed ever two weeks and water when dry, I have had the tree for around 5 years and never had a problem. First off I thought red spider mites so shook over white paper but can’t see any. Any help would be much appreciated.

Hmm... I see that folks have looked in, but it seems you're stuck waiting on someone with the right experience. So let's bump you to the top again!

I have some similar situations (dark or brown leaf tips), so I'm also waiting!...

I can't verify any of this, but from my recent research, dark or black ends of leaves like you show in picture 2 can be caused by too much water, not enough water, build-up of chemicals/salt in the soil, or an abrupt change to higher heat. So basically, it could be a lot of things. I'm certain that there are several people here that can guide you in the right direction, Philipk.

I would guess it's a fungal issue. It looks like a case of black spot to me. Chinese elms are very susceptible to it and I've had it on my elm this year.

Like Goldilocks and the THREE LEAVES !!!

Papa leaf said.....TOO MUCH WATER

Mama leaf said.... NOT ENOUGH WATER

Baby leaf just made water.

I don't acknowledge "fungal issues", it's not worth the worry.

I just had, or am having an episode, it's almost impossible for them not to be healthy enough to remove all the leaves and start over, so that's what I do.

Some people go out and buy fungicide, I'd recommend spending that money on another tree to enjoy while that one is slightly ugly.

I do a combination of spraying and defoliating. The fungus can live in the branches so even if you defoliate it’ll just come back. I went from having almost every leaf on my Chinese elm infected earlier this spring to now only having like 2 or 3 leaves with spots. I use bonide infuse systemic granular and daconil and liquid copper and it helps tremendously

I'm sure you'll need to dial in the watering better and water as needed, but I don't really know. I'd suggest using the search function in the upper-right corner and found it to be quite useful. There's a ton of information including similar issues to what you're having.
