Is there a difference. I think I have crab grass and I like it. Less maintenance. I am trying to make it spread in the yard. I used to have crab grass then I switched to fescue but that didn't work. I noticed a small patch of crab grass in the yard last winter then started watering it now its covering half of the yard. I wanted it to grow much quicker so I went to home depot and bought bermuda grass thinking it is the same as crab grass now I am wondering.
