Sawdust any good for mulch

Have a large bag of sawdust and wondering if I can use it around some rose bushes.

Sawdust will pack down pretty much with the rains, ,and if it contains any PT dust, it will not be good for the plants. Shavings, on the other hand are in larger chunks and don't pack down so much. I think if you scatter it lightly, once it decomposes it will do good, just don't put it on too thickly.

I was thinking the same thing... sawdust really needs to be composted, or at least mixed with the soil so that it isn't too thick, not just scattered on the ground like snow. Sawdust will help keep moisture in the soil, but one of the drawbacks of it is that it can mold.

I throw my non PT sawdust in the compost heap and occasionally on my garden.. I've never tried it as a mulch but I think you would have to put it down pretty thick to control weeds.
