What's wrong with my conifer?
We moved into our place just over a year ago and inherited a very well established garden with a number of conifers at the bottom of the garden. Over the summer one of the smaller conifers, in fact, the smaller part of one much larger conifer started to go brown and now its gone completely brown with smaller brown patches spreading to the one behind it and two of the others.
I have done a lot of research on this and I am none the wider.
According to various sources it could be aphids, but then it could be root fungus or having checked with our local garden centre they think its not getting enough water. So I am none the wiser and I don't know what to do about it. If it could spread then I need to sort it out sooner rather than later as I don't want it to affect the others.
I wonder if anyone on the forum might know what this is as I a little confused and a little stuck.
I include a few pictures that may help.
Thank you, I appreciate your help.
