This information was most helpful. There was an article in the local paper that contradicted the ash information and happy that you could clarify this!!  
someday hope to enroll in classes!

Glad that you found the wood ash informative and useful.  
There is often conflicting garden information at times in newspaper articles that are often written for national syndication, especially on wood ash. As written in the blog, this is primarily because the soil east of the Mississippi River tends to be acidic (pH<7) and wood ash can be useful in the garden, whereas in the Far West, and specifically in Contra Costa County, the soil and water is alkaline (pH>7+) and addition of wood ash makes the soil too alkaline for the health of most garden plants.  
Here's to a bountiful spring garden for you and all Contra Costa County gardeners!!!
