re: Msm Turf questions

Yes to all, temp and your grasses, and I seem to recall there is a Site One Landscape in the Suburbs of Savannah that should carry it. In Baton Rouge some, but not all, independent retail garden centers carry it as do at least some sod suppliers, and feed & seed type stores often carry it. Maybe a Tractor Supply store? You’d need to check.

I should note if you read the label on MSM Turf it says don’t use at temps above 85 F but I’ve used it a higher temps safely and this was on the advice of horticultural professionals. If you find it, all the application rates will be in oz per acre. So you don’t have to do the math, 1/8 teaspoon or 0.5 grams per gallon + 2 tsp of surfactant for spot spraying will work. Be prepared for a follow up application in 3 weeks. Expect some temporary yellowing of St Aug and centipede but it will recover.
