As with other products, natural or otherwise, a little coal ash can be a good thing but too much isn't,

It changes the ph level of the soil probably. You need to do a ph test to see if your soil needs amendments. It may either be too alkaline or too acidic. A ph of 7 I believe is what your looking for but it depends on what you are growing. For instance tomatoes and blueberries love acidic soil.
