Composting works by mixing organic material with water, oxygen and time until you get a rich fertilizer. But, the process only works with the right proportions of “greens” and “browns.” Greens, like veggie scraps, contain nitrogen; Browns, like dried leaves, contain carbon. (To nerd out more, start here.)
In your kitchen, you’ll mostly collect greens. With that in mind, here’s a handy set of do’s and don’t’s to reference when you put stuff into your compost basket. Feel free to call 720-695-2343 if you’re ever unsure. Every Soil Cycler will get one of these cards to stick on their fridge, but if you lose yours or just want another for posterity, here’s a spare you can print out.
