Most fruiting things (besides Honeyberry and Haskap) like their soil a bit on
the acid side and I don't see a sawdust mulch changing your pH enough to make
that an issue. The mulch itself didn't hurt my orchard: the trees with the
mulch always grew better than the unmulched trees.

My concern with what you are doing involves the mouse habitat you are
creating. I am quickly becoming a self-made expert in what brings mice into
an orchard and my personal experience shows that your plan makes the nicest
homes for mice who will then repay you by eating all the bark off your trees
the very next winter even when you have 18" tall hardware cloth cages around
each tree.

I also used to mulch with sawdust from our local mills and I also used to
make a doughnut of animal bedding out from the bases of all my trees. I
discovered the hard way that that trees aren't the only living things that
loved what I was doing. Won't do either of those things ever again.
