Got my soil test results back

I have a centipede lawn that is constantly under stress and it’s going to seed even when I’m watering every few days. Also, my 21” mower leaves stress tracks in the lawn along the wheel path. Not uncommon to see the blades turn slightly purple or yellow in these strips.

Well, it’s finally starting to make sense. My pH is at 7.3. From what I’ve read and have been told, this needs to be much lower around 5.5 to 6. So, I started my first sulfur treatment over the weekend by putting a couple of pounds down over an 800 sq ft section. When I rolled the garbage cans to the end of the driveway this morning I realized that I’d just committed earthworm genocide. They were retreating to the driveway and the street while yelling earthworm expletives at me. Some of the poor little bastards had yellow flakes stuck to their skin. Felt kinda bad.

With it being so hot, will 2 lbs kill my lawn? I’ve heard to wait until fall when it’s cooler but I decided to take the risk. Will do another treatment in a month or so if my first app doesn’t kill it.
