For some plants such as Roses, the saw dust will rob nutrients from the soil
as it begins to break down. Other than that it should not hurt.
That said, IIRC you want to mix Lime into the clay/Gumbo to break it down.
Yes and no...oak is very rich in tannic acid which isn't conducive to
most veggies, etc.
At least compost it before adding it to the garden and a heavy dose of
lime to neutralize pH will help. The clay will benefit from added
humus, but you need to test the soil for needed nutrients and acidity
before just dumping stuff in if you want to really improve the soil for
growing stuff, that is. The rhod'ys and azaelas will like it,
though...they need acidic soils.
It takes about a year for the saw dust in the soil to start breaking down
enough to release nitrogen. I started composting my saw dust about 15 years
ago. I added nitrogen for a year or so and then stopped. My soil is rich and
Walnut is toxic. It is not good for the micro organisms in the soil, for the
worms, for horses, for anything. I agree, don't use walnut or redwood.
Redwood has a chemical in it that retards growth for stuff that is not
I hear that walnut is toxic all the time. Yet, my parents had 70-foot
walnut trees in the backyard and grew all sorts of flowers and
vegetables under them. However, the trees are messy and the fruit
stained the concrete patio. I heard that walnut sawdust should not be
used in horse stables.
And redwood bark is used for mulch in California all of the time as well.
I was just saying that there are some places where the plant/sawdust
characterisitcs are desireable. It breaks down over time.
And because I like to use walnut for furniture projects, it's nice to have
somewhere to use the chips & sawdust. Like paths & such.
It depends on what, in particular and also on particular soil pH, etc.
as to the extent of the effect. Foilage on bulbs, in particular, are
likely to show signs...it's not so strong and effect as to be deadly to
virtually any plant, but in general, a comparative specie outside the
influence of the walnut will typically show better development than one
within that influence. I'd not use it in veggie gardens simply as a
precaution against poor germination, etc., not that I'd be concerned w/
human toxicity, etc. I also made the recommendation in context of the
OP in this thread asking about using fresh sawdust directly...

Fresh sawdust placed in the garden will deplete the soil of
nitrogen--don't do this. Instead, create a heap of 50/50 sawdust and
grass clippings and turn it every couple months. The initial heap
should be at least 3x3x3 foot for composting to work well. After 3-6
months, it will be composted and can use used in your garden. If you
don't use grass clippings (or green clippings), the sawdust will take
much longer to compost. Adding compost to clay soil will greatly
Some of us gather our nitrogen from organic sources (horse stables), adding
to the aroma. Mulched under black plastic for a month or so, the weeds are
pretty much history.
Or the OP can wimp out, and throw it in the greens bin, and let the
municipality deal with it. Not everyone wants responibility through the
whole carbon cycle, anyway.
Does taking a leak on the compost pile preclude Christianity? It's never
been mentioned in my doctrinal studies...
I've no idea (I shall try to find out on Wednesday when I ask someone
knowledgeable about the Somerset settlements).
In modern times though, barbecues full of pagans seem amenable to the
idea of communal pissing on the compost, but I can't imagine the
vicar's tea party going for it.

Indubitably, my dear Dingles.
I take the easy way out. I burn my leaves (two piles a year) and pick
up a full truck bed (cubic yard) load of JoGrow (community compost)
from them once a year for $9. I'm going to the fully organic stuff
from the other place this year at a premium: $20 a load.
I think it's the essence of it. Every time I think of those preachy
