Old cardboard boxes have
found a place in our forest gardening plans as a cheap source of mulch.
We save all our household
cardboard and then get a decent amount from our chicken waterer business,
but it wasn't enough for Anna, and back in the winter she started
wondering where we could get more.
I went around to several
local retail stores and found out there is a new policy where stores
pack up their discarded boxes and ship it all back to the original
warehouse. That put a crimp in our cardboard mulching plans until
Kenneth, the super nice maintenance man at the local school where we
tried our worm experiment asked if we could use any "pasteboard",
which is what some folks call cardboard around this area.
They had a truckload and I
started getting more each time I went to pick up the food scraps for
the worm bin. I'm not sure what other places do with their waste
cardboard, but it might be a good source of mulch if you have a school
in your neighborhood.
