How know if soil is TOO acidic for blueberries?
I planted some blueberries last year. I got alot of dead wood on them this year. I put them in a large % of peat moss to soil ratio... I was curious if there's a thing as too much peat moss for blueberries? They also have pine needles on top as mulch... They get a good amount of morning and decent amount of early afternoon sun.
I'll probably test out the soil soon but thought it was 4-4.5.... but curious, can blueberries do well in a very high peat-moss medium? For a 100% peat moss medium, would that even get to an acidity lower than 4?
