I have maybe 5 or 6 cups of the grains. I was thinking of doing some spot composting with them in the garden bed. I just dug up a clump of irises and noticed the soil needs some work. I don't think I'll put all of it in one spot although I could do some smaller spot composting sites. Plan is to dig a hole, dump some in and cover back up with soil. My compost pile is currently covered with weeds (my pile doesn't get hot) - lots of work just to mix in the grains at the moment.
