Are Wood Ashes Good For The Garden?


Ashes in the Garden  ??

You may have heard that using wood ashes on your garden can help make the soil more fertile.  Though ashes do contain significant amounts of potash, they contain little phosphate and no nitrogen. Most Kansas soils are naturally high in potash and do not need more.  Also, wood ashes will raise the pH of our soils, often a drawback in Kansas where soils tend toward high pH anyway.  Therefore, wood ashes add little benefit, and may harm, many Kansas soils.   In most cases it is best to dispose of cold ashes in the trash.
