Sawdust on lawn or garden?

habiem(5)June 10, 2007

I recently completed a home project that made use of a lot of 3/4" oak plywood. As a result, I have a LOT of sawdust. Before I just throw it into the trash can, is there any use for it on my lawn or garden? Is the glue used on the process of making plywood problematic? If so, can I make use of cedar or pine (obviously NOT pressure treated) sawdust, as I regularly have those laying around?

You can, and it's an organic material. Like you said, don't use pressure-treated (or any kind of treated) lumber--if I remember arights, the arsenic levels are pretty high.

I'm not sure about the glue. It's probably a plastic or rubber-like thing, so it won't decay.

Now a warning. :-) Wood is a "brown" and very high in carbon. It's going to suck up nitrogen to decay (and then release it as the decay process continues). You'll want to counterbalance that with a nitrogen source.
