Wood she’s in my garden
I’m in Tucson AZ. I burn mesquite firewood in the winter which has a lot of ash. My soil is just about pure sand,a bit on the alkaline side. I want to get some benefit from the ash, do I dare put it on my garden or mix it in my big cow manure composting piles?

Thank you for your question. Wood ash is also alkaline, and used as a soil amendment to reduce acidity. So, if your soil is already alkakine, adding it may make some nutrients unavailable to your plants. Adding it to a compost pile, whose other organic materials are acidic, won’t hurt. Here is an Extension article about biochar, which your woodash is a variety of, which explains its creation and use: https://extension.arizona.edu/sites/extension.arizona.edu/files/pubs/az1752-2017.pdf Hope this is helpfil!
