Good idea!

& it brings back some memories:

Years ago, an old friend was re-modelling Billy Bob's, a country western club in Arlington, building bars & tables from beautiful red cedar.

He was griping one day about all the shavings & sawdust he "needed to burn".

Eeeeek!

After he finished laughing at me & shaking his head, he brought me a bunch of lawn bags full of fragrant, beautiful cedar shavings, which provided mulch for one season before they decomposed into the earth.

Saw dust and wood shavings are not friends to anyone's garden unless it has aged very well. It has to break down and in doing so will rob nutrients fromt he soil underneath. Too close to plantings encourages rodents too. Check out Mike Mcgrath's You Bet Your Garden site. Full details there.

Actually, there have been recent studies showing that it doesn't use up your nitrogen if you use it as mulch only. It will if you dig it in though. For compost, mix with grass clippings. But for mulch it is fine. The biggest risk is it clumping or compacting if it's too fine.
