Yes, I need to remember that the mulch isn't going to
block weeds while "magically" allowing the passage of the new
shoots from plants that I want to grow. Also a few inches
down the wood chip mulch combined with fungi can harden into
a relatively solid mass, so this needs to be broken up
periodically if any new shoots need to be able to penetrate it.

Indeed. Such a solid mass that it's being used for all sorts of things.
