Classic drought symptoms - have you had any rain?

I could be imagining it (it's not clear from the photo) but this also looks a bit like herbicide damage.

Do you have any more photos ie of the whole tree (s) and surroundings

 

Is the wilting the same all over or just on certain limbs/trees?

[TonyP]

I will get some more pictures tomorrow of the tree's for you to have a look at with camera as that was taken with my phone so not very clear.Now you mention the herbicide they have had someone in to spray all the nettles recently so you could be right and it is the whole tree that has been affected.

More pics of the tree's taken today

Have finally found out it was mptca (hope thats right) that was used to spray the nettles around.Would this cause the tree to look like this or do you think its something else??

sorry it was mcpa not what i put above

MCPA is a broad-leaved weedkiller sprayed on cereals; been around a long time. It must be surface-absorbed so perhaps it was applied in windy conditions if it's the cause....?
