Wood Ash for the Garden to Raise pH Level and Add Nutrients

We gathered brush all year and placed into a pile in the corner of the yard.  We had no way to dispose of it, so we were planning to have a nice bonfire one cool fall evening.  We have quite a few trees in our yard that need the periodic trimming, and we removed a few large bushes so this brush pile had become rather large.
