red maple/beech mulch and blueberries: why not?
So I was about to dump 3-5 50 gallon barrels full of soft (red) maple shavings on the blueberries, when a nagging feeling came over me that I had read something somewhere....
Sure enough a little time on the internet and I find several references to red maple and beech, leaves and wood being identified as retarding their (Blueberry) growth if used as mulch.
No big deal I have lots of places to dump shavings, and it's rare that I run soft maple or beech through the shop.
But nowhere did I find an explanation. What is the reason? And is it species specific to blueberry or are there other things that should not get mulched with this stuff.
I have never seen reference to any plant toxins,like you can get in walnut and some of the other rot resistant species.
Anybody have any insight into this?
