Not sure if this is in the right section or not....

Now that I'm spending time clearing lots of brush, overgrowth, and 10+ years of neglected growth, I've been doing lots of burning. The result of which is that I am accumulating a fair amount of ash.

So the question is - what do I do with it? Should it be incorporated into my growing mulch pile, or is there something better to do with it?

I've already learned that about everything has some use, just not sure what the right one for this is....
