I have a 40' long row of raspberries that have dragged their feet over the years. Recently I was told to check the ph of the soil. I just bought a ph meter and measured 7.5 to 8 ph across the row. I understand that raspberries like the soil ph to be 5.5 to 6.5. What's the best method to lower the ph of my soil here?
Thanks in advance - Mike
