    Wish it came with instructions...

    I need to lower the ph in my soil. I purchased aluminum sulfate because it works more quickly than ammonium sulfate. I was hoping there would be some information about rate of spreading (e.g. lbs/1000). Something like pools use for adding chemicals (eg. if you want to drop it x use y rate).

    Boy that bag was no joke 44lbs

    I can't wait to get this into the soil. Thank God there're companies like this that don't try and take you for a ride on costs. I'm just trying to get a good healthy garden going. It was a good deal for 44lbs and our soil was way way off. Not unfixable, just in dire need of amendments. Everything was either too high or too low and when I say low I mean loooow. Seriously though, thank you guys and gals. I'm putting everything in this weekend. It's like Christmas.
