I bought a new home a little over a year ago and the lawn is your standard common bermuda. The total square footage of front/back/side is probably 2.5-3k, but I'm only concerned with the front and back (~2k total max) because the houses are close enough that the sides just don't get enough sun. I have a manual reel (American 7-blade) that I keep sharp. I mow 2-3 times per week @ 1.25" (would love to go lower but need to level the bumpy lawn first). I installed an irrigation system last year and water deep and infrequently. I have a lawn service for fertilizer, although I'm about to stop that and go off on my own. The lawn was last aerated and fertilized (28-0-3) about 3 weeks ago. I mow low and often. You cannot find a weed. I water deep and infrequent. As a last resort I even applied some liquid iron last week (I went a little heavy) yet the color and density are both light. I'm not sure what to do. I'm doing everything, what I read, to be correct yet my grass is light green and thin while all my neighbors, who do everything "wrong" (i.e. mowing at 3-4", watering 15 mins every day...at night, 10-10-10, or 46-0-0 every couple days) have a much fuller, darker lawn. I know that longer heights typically yield dark colors but the difference is shocking. The fact that the liquid iron did absolutely nothing for the color is alarming. I have a neighbor who recently leveled his lawn and threw out a gargantuan amount of fertilizer. Lawn is the deepest color green. He went and bought a used reel and took it down from 3" down to 1.5" overnight and it's still dark and lush. I always read about how indestructible and invasive bermuda is yet I'm not seeing any of this. Any thoughts???
