conifirs going brown

[Philtaz]

Sounds like something is causing them to slowly die off. Have you got any nasty neightbours?

[Drewhound]

I've heard of this several times recently. It may be due the unseasonably hot and dry spring we had

[Kev_UK]

Is it a question or a statement huh? If a question, then could be lack of water or cat pee

You don't even say which conifers. Some do periodic needle shedding. Without more info, it would be impossible to tell. Would need to know where you are, has there been a drought, are the needles browning from the inside out or outside in, which ones are they, when were they planted, etc. Newt
