off season soil acidification for blueberries?
just wondering if there is any value to adding soil acidifier now (winter here in MN) it would be dispersed into the soil very slowly with each partial melt until the full spring thaw.
I have blueberries in soil amended with 50% peat two years ago and treated with sulfate. some plants have done OK, some others still appear to need more acid soil. lowest Ph I got was 6.0
I have aluminium sulfate or ammonium sulfate for treatment, no sulfer although I'm wondering if I should buy some.
suggestions or advice welcome.
