So, a while back, my sister deposited a home composter in our back yard. After staring at it for a long time, and plotting to get rid of it, I finally decided (last year) to start using it. I've been tossing in all our veggie scraps, my coffee grounds, the odd paper towel (with the coffee grounds), and yard debris (mostly weeds and vines). It's on grass (as the company website suggests), but for some reason, things just don't seem to be - well - composting. If I peer in the vents on the sides, I see last summer's vines apparently still intact. I was hoping that after a year, I'd have something to show for it.
