A thick layer of sawdust--especially if it is laid over several sheets of newspaper--should serve quite nicely to keep weeds down. You could also use it as a mulch around individual plants--however, because sawdust contains lots of carbon, you may want to fertilize plants with a fertilizer containing nitrogen, to help keep soil microbes happy. You could also till the sawdust into the garden. If you do this, I would wait at least 2 weeks to plant, again, to give soil microbes a chance to begin breaking down the sawdust. If you add lots of carbon-containing material to soil, you can induce a temporary nitrogen deficiency because the microbe population rises, tying up available nitrogen temporarily. Hope this helps!
