Lot of good points here. I think the problem most people have is that they scalp their lawn too low. I’m mowing at the second highest setting every 3 days or so. In spring it was every other. Times are kind of tough now because we aren’t getting a ton of rain and it’s been so hot. When things cool down in late summer and early fall would be the time to get your lawn rejuvenated. I have some problem areas and plan on dethatching, aerating and Overseeding this September. Just hung up on what I want to use for my shady part of the lawn because I don’t like the fine rescue that typically thrives in shade. They have some shade tolerant Kentucky blue grasses but even their survival rates are only 82% and the seed is expensive.
If you want to do it yourself I’d check out this YouTube channel. Videos are informative without going to deep and he typically uses product you can buy locally.
His lawn when he uses the reel mower in the front is INSANE. I wish I had his dedication to have my lawn look like that.
