Please help identify what is wrong with my tree's
 
Hi Everyone,

I am new to this forum so please be patient if i do anything wrong.

I have a quite a few trees which are in the process of training, all of them have either been gained in the wild (yamadori) but some of my oaks i have grown from seed.

They are Willow, Oak, Sycamore, Norwegian Maple, Poplar and ash trees.

The problem is that they are all close together and have now all been infected with something... I am unsure of what it could be... after a lot of research i think i have found the problem but cannot be 100% certain. Last summer they had a light case of mildew but this summer they are really poorly.

I think they have some black or grey spot but i can't be certain, the tree's that are mostly effected are my ash which is my biggest concern, they have very small spots on quite a few leaves and some are dying back, the leaves are turning brown and curling up, then falling off. I was uncertain if this was "Ash Die Back", if so would this have transferred to the other trees i have.

I am not sure how to add a photo to show you, maybe someone could please help?

In desperation.... Any advice would be fantastic.

Kindest Regards

Ranni

I have found out how to uploads images, as you can see the spots on the willow tree are many, the leaves get covered, then turn yellow and fall off. The Leaves on the sycamore are big deep black blotches, some of them have black blotches and others have like dark brown blotches.

My main concern is that of the ash tree (presumably it is an mountain ash), i am very concerned of this one as she is my pride and joy (roots and form) i was wandering if this was suffering from some kind of black spot or was it Ash Die Back (praying to god it is not and it can be sorted.) I have attached a picture of a mark on the trunk, there a few of these on it popping up i have noticed??

The tree's that seam the least infected are the oak's but are showing some signs of problem now.

I have now separated them.

Any help would be great
Thanks for reading

I have more pics if required - anything to get this problem sorted

It doesn't look like ash die back to me.

From your pictures it looks more like the fungus Rhytisma, which causes tar spots i.e. the black spots you can see.

An appropriate fungicidal spray may help, but before you start any treatment I'd space you trees out more as this fungus is transmitted in the leaves that fall off.
