Wood Ashes

Do any of you use wood ashes on your lawn or garden?

The reason I ask is because a Ph test last year indicated that my back yard is slightly acidic (5.8 I think). From what I've read, wood ash can be used to raise soil ph. (plus add some potassium) I'm considering apply some to my lawn and would like to get your opinions before I do. I have a large oak tree that drops lots of leafs, sticks and small branches and I have collect a large pile now.

Should I use them on the lawn? If so how much?

Any other thoughts or concerns?

RE: Wood Ashes

I use wood ash in both my vegetable garden and lawn. I got this off of a website. Hope this answers your question.

Ash is composed of many major and minor elements needed by the tree for plant growth. Since most of these elements are extracted from the soil and atmosphere during the tree's growth cycle, they are elements that are common in our environment and are also essential elements in the production of crops and forages. Calcium is the most abundant element in wood ash and gives the ash properties that are similar to agricultural lime. Ash is also a good source of potassium, phosphorus, magnesium, and aluminum. In terms of commercial fertilizer, average wood ash would probably be about 0-1-3 (N-P-K). In addition to these macronutrients, wood ash is also a good source of many micronutrients that are needed in trace amounts for adequate plant growth. Wood ash contains few elements that pose environmental problems. Heavy metal concentrations are typically low and not in a highly extractable or available form.
