I am sure there is a more appropriate place to post this, but ... here goes.
I know my plants, but I don't know my lawn. AT ALL.
I think this Bermuda grass, and the pictures below are of my front yard, south facing, in Texas. Hotness will be coming very soon.
The lawn care people - who we let go, for economic reasons, were re-consulted and we were told the grass was dead. There are weeds pushing up through. We don't treat with herbicides, and I have been pre-occupied with my veggie garden and my flowers to deal with it.
(1) Is this grass dead?
(2) Do we need to re-sod?
(3) If it is only mostly dead (see Princess Bride), will it come back without us trying to find the money to re-sod?
(4) Can you oversow Bermuda?
