I know a lot us out here make our own soil or at least improve on something that we buy. And the smarter ones of us sift it to ensure good drainage. The question is, what to do with the fines that are unsuitable for bonsai potting use?

With decomposed granite, after sifting and washing I am left with about half the volume, even with the fired clay I am left with a significant amount of fines that are unusable and I was wondering what everyone here does with the leftovers. For now, I just toss them into the garden and will work them into the planting beds in the spring, but that seems like a waste to me.

I'd especially like to hear from our professionals, whom must go through bags and tons of soil components.
