Lawn troubleshooting

Honestly, looks like pretty much everyone else’s lawn after last summer!

You can try applying a thin layer of peat moss and applying a fert with a higher rate of phosphorus and potassium. Something like a 20-20-10 would be my choice. It could have been take all patch or drought related. Difficult to tell from the pictures. I'd also consider getting a bottle of Celsius based on the fact that you have dicondra in your lawn
