    Depends on the kind of wood. If it was treated with anything I wouldn't.

    sawdust that is fresh has to go thru a heat or a season, old sawdust would b ok
    fresh would kill plants

    It depends on the type of wood that the sawdust comes from... pressure treated wood has been treated with a pesticide and other chemicals so the saw dust would not be good for food crops... rail road ties are not good for this either... to be sure.. check with your LOCAL nursery... they will have the best advice.

    Wood chip mulch from big box diy store will do just fine. Used it for years...

    It also depends on what kind of wood. Not pressure treated, for sure. Sawdust from cutting a tree or firewood might be OK. I've never seen it used as mulch, though. I'd be cautious.

    I agree with Kim. Don’t use fresh sawdust. After it has composed awhile it should be ok

    As long as it is not from treated lumber it should be okay.
