re: Suggestions for weed control this time of year?

It might be easier for you to order the MSM Turf on Amazon, 2 oz bottle is plenty, and 1/8 teaspoon measuring spoon, and have that available for use in warm weather conditions. 85 F+. You don’t want to use this until your St Aug and Centipede are fully greened up.

You can also order Hi-Yield Atrazine and Fertilome Weed-Free-Zone and Hi Yield surfactant from Amazon and spray it if temps are less than 85 F. I know you’ll be hot in Savannah this week, but looks like you’ll have nice cooler weather next week. Use of this “cocktail” does not require the lawn grass to be greened it. Good size retail plant nurseries usually carry these products, and as well good size hardware stores, at least they do in our area of Louisiana, but who is going to be open......,

You can spray the entire lawn if covered in weeds or spot spray clumps of weeds.

Below are the “recipes” - follow the instructions and read the labels on the bottles of herbicides. Note: the MSM Tuft recipe for Virginia Buttonweed is applicable to most, not all, weeds in your lawn.
