Something dead in dormant bermuda
My wife and I recently bought a home and the yard is going to be quite a project since it has been severely neglected. We're in the DFW area, so the Bermuda is still dormant. However, there are dark/black areas throughout the front yard, that I believe may be dead Bermuda, but I'm not 100% sure. Hoping it's nothing disease-related.
I've attached a few pictures of the yard. The first includes the neighbor's yard to help show the contrast (not that it is necessary). Then there is a closer up picture of a black area, and then a picture of some of the pieces I pulled out.
What can I do about this? I'm familiar with the general rules of thumb for maintaining a Bermuda yard, but I'm not sure fertilizing, aerating, and deep watering once a week when the Bermuda starts to green up is going to be a solution for this large of a problem. Or perhaps it is. Any guidance/advise/tips/comments are appreciated!
