How can I prevent pine needles from turning brown?
Place mulch or barriers around pines if runoff is an issue. If runoff cannot be eliminated, then reducing its impact might be possible. More likely than not, this will need to be a lifelong prevention method. As the pine and soil recover, the browning and needle cast will slow over time. Close up of dry pine needles.
