I have roughly 50 feet in length by 10 feet in height conifers in my garden. Quite a few of them have gone very brown, brittle and dry looking. I live in Scotland so we don't lack in rain. Can you give me a reason as to why this would happen and how I can save them please. Last year I did put down black membrane and chuckies to stop the weeds coming through. Have I starved them of water?
