Hello. I’m wondering if anybody has some helpful ideas with my lawn. This actually started to happen last summer. I have a lawn care service that fertilize the lawn certain periods throughout the year. The line from them is that all this will get better or if not they will simply over seed. It is so patchy I’m wondering if over seeding would be the right option or am I going to have to look toward something more drastic? It’s also funny that this is only a central area in my backyard surrounded by decent grass, i’ll be at none of the grass looks entirely healthy yet. We live in the eastern foothills of the Sierra Nevada’s outside of Reno Nevada. Moved from a Nebraska where you actually had to make a concerted effort to try not to have a nice lawn Thanks!
