Back again to the all knowing group mind to suck some more knowledge from
the experts. I have read in many places not to burn plywood scraps in the

I have been spreading my sawdust in the garden area between the raised
beds (NOT in the raised beds!) and the grass is just as green as
anywhere else for 2 years now. If it will hurt flowers or shrubs, I
don't know but I would doubt it. Unless it changed the PH dramatically.
You might want to spread some nitrogen first but I doubt that sawdust
used as mulch sucks it up out of the ground.
This is a combination of oak, oak ply, 5 different kinds of regular ply,
birch, birch ply, maple, popular and pine. there is some folklore (that
should raise a stink) about walnut or black walnut but I don't use any
of that, yet.

Believe you'd get more glue than wanted as both rely on adhesives in
manufacture.

Yeah but you can eat the greens from the dandelions...see...you have a
veggie garden and didn't even know it.

An unkind remark is like a killing frost. No matter how much it warms
up later, the damage remains.
Can actually be an advantage. Remember nitrogen=foliage, not fruit. Does
wonders for the potatoes.

Help on the nitrogen issue mayhap, but think of all the weed seeds you'd be
introducing into the mulch that's supposed to suppress weeds...
Well, unless you have one of those artificial, chemically sustained
monoculture lawns with nothing but grass growing in it.
Me, I have a crop of dandelions with a few tufts of grass mixed in. :)

From what I have read, done and heard from the Saturday gardening specialist
on Saturday radio, sawdust can be very good mulch. It does take nitrogen
from the soil as it decays. It was suggested to mix some high nitrogen
fertilizer with the sawdust if used directly as a mulch. How much, I don't
know. It is much better to compost the sawdust first. Sawdust by itself
doesn't decompose very fast. There are some liquid additives that can be
obtained from the local gardening center for composting dry leaves that aid
in enhancing the decay process. Also, you can mix it with other compost
material such as kitchen scraps. Sawdust from Walnut and treated lumber
should not be used. I don't know about ply and mdf, but personally, I
wouldn't use it unless it is small amounts mixed in with regular sawdust in
the dust collector.
At home, I apply straight sawdust over the whole garden after the plants are
up. I don't mix anything with it or compost it first (too lazy), and garden
produces well every year.

Sawdust as a mulch is fine, just don't dig/rototill in. When dug in, that's
when you have trouble with the nitrogen.

Don't know but doubt it would work. Might check rec.gardens.

Plywood contains a lot of glue, and some formaldehyde, I think, so I'd
call a plywood manufacturer.
: there is some folklore (that
: should raise a stink) about walnut or black walnut but I don't use any
: of that, yet.
Walnut shavings and dust are seriously toxic to horses:

http://www.vet.purdue.edu/depts/addl/toxic/plant45.htm
In addition, walnut trees produce a natural herbicide called juglone,
which I imagine would mean walnut is a very poor choice for
mulch.

True enough, as wood decays it removes nitrogen. Mixing the sawdust with a
goodly amount of grass clippings will help out a fair amount.

I've read in multiple different places that you
- can use sawdust as it is a good organic mulch
- should not, as it attracts termites
So I think the jury is still out on this one.
As for the dark brown mulch you buy in the store - it is cedar shards,
and is naturally termite-resistant because of cedar's natural thujone
content.

I avoid using any composites, such as MDF, plywood, etc... and their
shavings and dust, in fireplaces, gardens, pet cages, etc...
I may be overly cautious, but it's worked for me.

Tried it. Bleah. Too bitter to eat.

Sawdust in general is bad mulch because it takes nitrogen out of the soil as
it decays. I am guessing that hardwood mulch is okay because it takes so
much longer to decay, but don't really know that.
Nor do I have any idea if plywood dust is worse than wood dust.
