Nothing added to soil will keep the pH low enough to grow blueberries unless the
pH is already low. Horticultural sulfur may help, but not likely. Peat moss
has a low pH, but not substantial enough to develop an acid soil forever. It
also gets used up fast in warm climates and adds nothing to the soil structure.

I was considering growing some blueberries in a large container this year. I
still may. It's much easier to keep pH low in a container. They really do need
a 4.5 to 5.0 pH to thrive. There may be some new varieties which can be
relatively productive with higher pH, but they have to be sought out.

I was reading Gene Logsdons "Gardener's Guide to Better Soil" just this
morning and he recommends using peat moss as an additive or oak leaves could
be another amendment.

I'm putting a couple blueberries in, and I like to stay organic with my
garden..
What is the best organic way to lower the Ph of the soil so the
blueberries
are happy.
I've read : saw dust is one suggestion.
