Lawn weeds/moss or something else?
I moved into a house that was vacant for the best part of a year. This year I want to do something about the lawn and I have these weeds/moss or whatever they are on it. I am not even close to knowing what I am doing, but I would love if someone could identify what these are and tell me how to prevent them/kill them. 80% of the lawn looks ok, but there are parts which need some TLC for sure. The pics are 4 different shots from different parts of the lawn and I pasted them all together. So they would be quadrant 1,2,3 & 4 going clock-wise I suppose. Maybe they are all the same type? Any help is appreciated.
