fireplace ash components

Asked March 15, 2015, 9:18 PM EDT

I want to use my wood ash from the fireplace on my lawn and garden beds but I regularly use cardboard egg cartons to start my fires. Would this component prohibit my use of the ash? I use one regular carton per fire which usually burns 4-5 good sized logs (maple and cottonwood and pine) plus a variety of kindling from those and also honey locust and catalpa.

In general, Front Range soils can benefit from addition of organic materials from any source. One exception is fireplace ash - which is alkaline, often high in salts and high to very high in "potash" or potassium salts.
Since most Front Range soils are already alkaline and high in potassium, adding fireplace ash is rarely beneficial.
