Compost Bin on concrete???
So I just purchased my first compost bin and I'm looking for the perfect location to place it. I'm debating whether or not I should put it on a concrete landing just outside of the back door to my garage. The benefit to having it there is 1) it's pretty much out of site and won't be an eye sore to neighbors (or my wife) and 2) I can get to it fairly easily from the garage.
The one negative is that it would have to be put on concrete (ideally). Does this present any issues? Do compost bins need to be in contact with the actual ground/earth to work? Should I worry about protecting the concrete (i.e. lay a tarp beneath it).
Just wondering if my "ideal location" might not be so ideal. Thanks.
