Does what work?
Sure! "It" works on everything... what are you talking about?
should but be careful about amounts.
Aha! Okay, it's very good for acid loving plants like azaleas, gardenias, etc. Don't work it into the soil because it's too strong. Just sprinkle used grounds around the base of the plant and it will leach into the soil when you water or when it rains.
