A couple pine needle pH questions
I'm using pine needles along with other methods to make my soil more acidic for blueberries.
Does anyone know if it makes a big difference whether the pine needles are fresh or dry?
Do some types of pine acidify the soil more than others? White Pine and Shortleaf Pine are fairly common in my area.
I would like to know if anyone has seen any detailed studies on using pine needles to lower pH and would really appreciate a link if you have one.
