I have 1.4 acres. It appears I have maybe 20 different breeds of grass, crab grass having a substantial minority hold on it. Other weeds I don't care about because they are mainly green. Some weeds have little white or yellow flowers in the late spring and early summer. They are pretty. Green is good, too. Crab grass gets sort of reddish about now. I ride around on a Husky 22hp rider and I wear headphones and listen to music. I don't pay much attention to how I mow it. I don't really care if I leave tracks. I don't think the grass cares either. Neither do the weeds. It rained a lot this year so I didn't have to turn on my irrigation system more than 4 or 5 times. When it doesn't rain, I turn it on for 20 minutes a zone over 6 zones every 2 or 3 days...when I happen to remember to turn it on. Sometimes I forget to to turn it off. It comes on at 5AM. I don't get up till 8. I know when I forgot if the day I am going to mow, the grass is still wet from the irrigation system. I have a couple more coffees and mow it later. I also turn the system off.
