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!
