I bravely clicked on your link, which showed only a small patch of lawn with some bare spots. If your issue is lawn, I think there's a separate forum for that. You've posted your question in the wrong forums. You'll need to take more photos, post them in the correct forum in order to get practical/expert advice. You should provide information about your zone (you can google how to figure out what climate zone you are in), perhaps how much sun/shade your lawn gets, and more information about how much you water and what you've tried in order to fix the problem.

Don't bother with a link to your pictures. Many people won't click on it.
