Fir bark mulch for blueberries
I have 2 raised rows of blueberries mulched with fir bark around them and in between..
My corn rows start about 4 feet from them. Question 1: Will the acidity from the blueberry mix, Or the fir bark used to mulch them be too much for the corn? The corn is a bit lower and there is run off in that direction from the blueberry rows.
And 2; Is it better to use redwood mulch for helping lower the ph of the blues?
