Put down Vigoro spring (fertilizer and crabgrass preventer) application about a week a go. Last weeks rain got it into the soil.
I cut the grass high (2.5 - 3in) tall. Keeps the root system cool and the weeds that come up down. For those that come up I make a mental note where those are and hand pull or cut out with knife from cheap leathermans tool. I alternate directions when I cut so the grass doesn’t get a pattern set in it.
I’ll fertilizer / weed in fall. I may spot spray weeds if I see something getting out of control. That’s it.
As far as the Ag coop extension office, many have good info on line.
