Hi folks, this is my first post on your site after lurking about for
several months. I wonder is anyone could be so kind as to offer any
advice or opinion on the condition of my conifer hedge. I first noticed
the browning about the middle of February this year and it has got
steadily worse since. The hedge has been in for about 14 years and has
always appeared healthy. As you can see from the images it is healthy
above and below the browning. I stay in Central scotland.
thanks

If I'd had to guess from those photos, and the plants were here in the US,
I'd guess spruce spider mite. However, that's pretty much a SWAG.
Best thing you can do is to take some cuttings in a sealed plastic bag to
a local expert. http://woodypests.cas.psu.edu/FactSh...ider_Mite.html

You can get similar discolorations from several root rots, too.
