Hummm....until this skill is developed what would your suggestion be for the question at hand? Also, I'm very curious as to how the eye can tell if a lawn is low on P, K, or CEC's are low and if that eye can tell it's low, how does that eye measure the amount needed to make the correct adjustment..
I have given several bids for lawn care this year for weed lawns. I don't spray them because if I did it would be a dirt lawn. I tell them to wait 6 months until fall and then get the lawn done. Most will like the fact that you are honest.
