Sick Tree :(

stuartwright800

Hi all, 
I'm new to gardening, so sorry if this is a basic question.
I have a tree in my garden and it looks like all the leaves coming from one branch have died. Please see pictures attached.
It seems like the tree has some healthy leaves which are green and shiny, some leaves which have lots of white matt spots on giving the leaf a rough texture, and some leaves are dead.
Does anyone know what is wrong with the tree? Should I aggressively cut away the poorly branches?
Any help appreciated.

Hi @stuartwright800  and welcome 😊 

I’m not sure what the problem is but the growth on that lower branch looks dead. I would certainly remove it at the base. 

Then I would give the root area a scattering of Fish, Blood & Bone fertiliser, several buckets full of water and mulch around with something organic ... homemade compost, wood chip etc.

Keep watering at the rate of two buckets of water twice a week until late September ... more often if we get a hot dry spell. 

It may not be lack of water that has killed that branch, but being close to a wall means that it will be in a ‘rain shadow’ even in heavy rain ... so feed and a bit of tlc will give it the chance to perform at its best.

@Dovefromabove - agree with all you said, looks like a very old Eleagnus??

I think you’re right @Bijdezee 👍

Thanks for all of the advice and also identifying the plant. I've cut the unhealthy branch back so fingers crossed.
Will give some extra water and fertiliser over the summer.

Thanks again!

You haven't sprayed any weedkiller anywhere that could have drifted to the tree?
