Disease

I'm hoping that someone can identify this laurel leaf problem which lines a drive to a park home estate where I live. I would only want an environmentally way of treating it. Thank you.

    Looks like powdery mildew.  Hopefully someone has some experience treating in on a hedge?

  • It was probably caused by lack of water. Some deep watering would improve the overall health of the plants. It's advisable to dispose any diseased leaves so the spores don't longer on the ground for a return but shouldn't affect the overall health of them as long as they're cared a bit better during dry spells.
