Ashes From Your Fireplace- Compostable or Not?
Curious Minds Want to Know
The reason wood ash is alkaline is that when it comes in contact with water it creates caustic lye. This is how you would make soap if you lived say, in a little house on the prairie.
Another reason you should use wood ash in moderation is that Cincinnati sits on a giant bedrock of limestone (also a higher pH) and shale. So we usually do not have acidic soils that you would need to neutralize. As always, we recommend testing your soils before using too much wood ash on your garden or in your bin.
