I was wondering if any of you have ever used cedar ashes in your garden or compost. I had heard that there are some oils in the cedar that either prevent vegetation from composting and/or interfere with plants growing. I'd appreciate any info. Thanks.

If burned as hot/cleanly as I hear RMHs can, I do not see how an oil especially ones found in cedar would still be present in the ash. Oil loves to burn, in my experience. Even so, depending the size, you would add only a small amount of ash to the pile.

I agree. Another consideration - soil pH. Better to use ash to raise the pH of acidic soil, not necessarily a great idea if your soil is already medium pH, and probably a bad idea if your soil is high pH. The trace nutrients in ash are good for any situation, but you just may need to use the ash very sparingly if you don't have acidic soil. I understand that ash actually reduces the amount of nitrogen produced by composting, however it still might make sense to put it in compost, for example if you have very poor acidic sandy soil like we have, because of the benefits of getting those trace nutrients and increasing the pH.
