Bringing up the acidic level in the soil?
nope.. pine needles won't do it.



Aluminum sulfate will lower soil pH. Iron Sulfate will drop soil pH and garden Sulfur will lower soil pH. this list is in order of potency and also in also in the difficulty to find. Go to a garden center (not a wal-mart) and ask their recommendation of the right product and rate of application for soil in your area.



good luck.
