    I thought the bags would have rates on them, instead all it has is a generic "apply up to one ton per acre". When I asked one of the guys at lesco about it he said (and hes kinda new too) that to drop pH from 8.0 to 6.8 you would need a total of 21 lbs per 1,000 BUT not all at once. Max rate per app was 4.5 lbs. per 1,000 2 times per year, so that it would take 4 apps to correct a pH problem in that example.

    Is that rate correct?

    Should I avoid applying over newly seeded/overseeded areas? It seems that in the past when I have applied sulfer to my own lawn (different brand that was mixed with gypsum) The lawn really looked bad after the application, mainly new grass I planted at the time, just seemed like it wasn't rooting in. First time I thought it was a fluke, second year it hapened again, so I think it's the sulfer burning the roots???

    Thanks for help!:waving:

    thanks... never thought to look there, lol. though that still dosn't have the spreader settings I was able to get a complete label for it! I have no idea WHY none of my 8 bags I received have instructions on them, the PDF of the label on the site was pretty much complete.

    glad to hear that, I could just imagine the guess work you were trying to come up with.
