The weird style of tree mulch in these parts (Connecticut) is small diameter
but very deep mulch.  Maybe that's what people refer to as "volcanoes." The
academics I know suggest wide and shallow, but it seems like all the
landscapers around here have decided to go the other way.  It looks pretty
strange.  On top of that, people seem to just be in love with that garish
red-dyed wood chip mulch.
The conventional wisdom among the academics is that deep mulch has a similar
effect to planting too deep.  The landscapers know that deep mulch really
keeps the weeds down.

Hi there,
Good info about the cypress mulch origins, Julie, I guess we have to assume
that is the case with much of what we get that isn't local. As far as the
volcano mulching - I realize that it isn't very pretty, but if you mulch up
to the base of a tree, tree girdling roots will form, ultimately killing the
tree. In the twin cities we lost thousands of trees a couple of years ago
(straight-line winds), most were found to have been planted too deep or
mulched up to the base. We are still trying to recover the urban forest lost
to Dutch Elm in the 70's.
Yours in the soil, Lisa from Mpls.
