I just got a soil test back for a new construction site that I got called in to fix. pH is 7.3 Lots of acid loving plants have already been installed into this soil and mulched in with some black mulch. I was thinking some Ammonium Sulfate, but then a web site Nick sent me to suggested some Aluminum Sulfate or the straight Sulfur. My question is; would you guys suggest that I drill the stuff into the soil around the plants (which is very compacted right now) or just pull the mulch back and do a surface app?
