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.

Elemental sulfur at the rate you put it down will not kill your lawn.

Thanks lawn bro!

Just remember it takes months for elemental sulfur to chemically oxidize to acidify the soil - slow process. I assume the AgCenter’s soil test results provided the you amount of elemental sulfur to be added to lower the soil pH to a target level with a a recommendation not to exceed “x” pounds per application over a period of months.
But if not, this Miss State pub does a good job of explaining acidifying soil in the home landscape with the recommendation on the amount of sulfur you should not exceed per application. LINK
Have your soil pH checked again next spring.

If you didn't give them 30 days notice you may be in some hot water legally.

I only received an email with the results along with some general guidelines for fertilizing centipede (not specific to my results). Haven’t received anything else, but I’m hoping they send me more detailed instructions in the mail.

Yes - the email results should be followed by a snail mail letter of results with recommendations.
Main thing you need to know is how much total sulfur required to lower the pH to an acceptable target, and the amount not to exceed per application, usually applied at 3 to 4 month intervals between applications. Might take a year or 2 to apply it all. You might consider aerating the lawn at some point before one of the sulfur applications.
