Hertfordshire, United Kingdom

I seem to have a number of problems with various items in my garden this year, maybe due to the harsh winter we experienced. Most can be dealt with but the latest thing to occur, or I have just spotted, is with a youngish Eucalyptus Tree. We inherited this but I'd hazard a guess at it being 4/5 years old. A few weeks ago I noticed that some of the lower leaves (can't see the top anyway!) had black marks on them and little raised "pimples"
It is sighted next to another shrub which has a few black leaves but is growing away nicely and producing new leaves. Now both are near a Photina which has definitely got Blackspot and is dropping leaves everywhere but again it is putting on new growth. However, yesterday I noticed that the Gum tree,s leaves at eye level have turned Brown and looks to be travelling upwards. I don't like to destroy any plant/shrub,tree but, in my opinion, this tree was planted in a very silly spot by the previous owners being sited right on a corner, practically on the drive and it gets full blast of any high winds. However, I suspect it would be no easy task to dismantle it even though it is relatively young.
Suggestions please.
