Without knowing by just looking at a lawn from experience (which I don't have), how do you determine which type of grass is growing in a lawn? I've read up some on types of grasses common to my state of NC, and seen pictures, which look very much alike in some ways. I think even if I had the pics in my hand and went randomly around trying to identify someones lawn grass, I'm not sure I could. Would getting a soil sample at your local agriculture department be the ones that could tell you when you take some of the grass in with your sample maybe? Just curious since this seems important to know if you get a customers lawn to take care of through the year with full maintenance of watering, fertilizing, seeding bare spots maybe, mowing height recommendations, etc.... Thanks for helping the dummy out here. Have a great fall season!
