New shredding as mulch?

In the archives there's quite a bit of info on this. But basically new
bark
chippings take nutrients from the soil as they rot down and this can
cause
shrubs to become chlorotic. When we do that sort of shredding here, we
pile
the chippings up in a corner for a year and then use them.

if it is twiggy material and green leaves, that will carry with it enough
nitrogen to avoid that however most likely eh.

Sorry, no idea. Twiggy material is still wood, bark etc. so I can't see
that will make a difference. But I don't know if the greenery left will be
sufficient to overcome the effects of the rotting bark. Possibly not, as
there's almost certain to be more wood than leaf.

If I put down anything too woody I apply either some manure or blood and
bone. I am assuming this will be green leaf and cuttings/twigs off shrubs
and nothing big or fire wood quality cuttings. If you are worried about the
mulch, use some blood and bone under it. If shredded branches, best weather
it for a few months.
