I'd suggest no more than 1/2 cup per square foot.

Cabin Fever you are correct. Wood ash increases the alkalinity of the soil (raises pH). Main use of wood ash is as a liming agent. Wood ash contains less than 10% pot ash, 1% phosphate, trace amounts of Iron, boron, copper, zinc, mag.. Also contains small amounts of heavy metals, lead, cadmium, nickel and chromium. Contains No nitrogen. You need to know the pH of your soil and what the trees/plants need.
Edit: Sorry I read the post wrong, I thought Cabin Fever was correcting herself. intead of Terri.
