Is it safe to add ammonium sulfate (Epsoma quick solutions) to soil when the ph reading is above 8? If so how should I go about adding the stuff. I have a bag of it bought from a home and garden shop and it looks like road salt that has been swept up off the streets of Buffalo NY after a long shitty winter. Anyway, on the back the directions read to mix something like 5 pounds per 1000 sq/ft, thus makeing it far more difficult for me to add it into a small pot with about 4 cups of soil/vermaculite, and perlite. Is using about 1 tsp per plant going to help the soil become more acidic?;)
