Q: I scattered lime around my hydrangeas and got some on my azaleas nearby. The pH of the soil around my azaleas is now 7.0, but azaleas like a more acid soil.

How can I correct this in short order instead of over years?

A: Changing pH is not a “short order” process…but you can drop the pH one point per year by applying 5 lb of 35% ferrous sulfate per 100 square feet now and once again in six months, followed by a soil test, to see what’s happening.

If I am not mistaken, Lilly Moss Out Granules contains ferrous sulfate.
