Fir bark mulch for blueberries

yawineyApril 8, 2013

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?

Thank you for reporting this comment. Undo

Neither pine, fir or redwood mulch does much to lower the pH. Actually any compost or organic matter will have a slight pH lowering effect as it decomposes, but we are talking slight here perhaps a tenth. If your corn is four feet from the edge of the bed you shouldn't have any problems. The horizontal migration of the lower pH are minimal.
