I use pine needles as much as I can get from my neighbors; the needles are
also good for cutting down the weeds.

Does anyone know a good way to acidify soil for blueberries *other
than* aluminum sulfate? We're not much into eating aluminum. Is there
anything natural? Could we use pine needles, and if so, how much?
