I consider composting a sacred act. A person who composts thoughtfully is a shepherd over the transformation from death into life. Without the holy cycle of decay and rebirth that the composter harnesses for her garden, life on this planet could not exist.
For your soil, there is no better ingredient than compost, whether you till it into your garden beds or use it as mulch around shrubs and trees, it is considered essential to organic and sustainable food production. Once it’s in the soil, finished compost—or humus—increases fertility, adds both micro- and macronutrients, buffers pH, prevents diseases, and improves soil structure.
Without compost, soil is just dead, inert mineral dust. Composting is not only essential for healthy plants and soil, but it can also remove 20-50% from your household waste stream, reducing the burden on landfills while replenishing your lawn, trees, houseplants, or garden for free. And if you pay for trash pick-up, composting can save you a lot of money, too.
A compost pile can be as easy as starting a heap of veggie scraps, dead leaves, and grass clippings in the far corner of your yard, but most people like to contain their compost in a compost bin.
There are many different kinds of compost bins to fit every living situation: simple pallet bins, tumblers that make turning the compost easy, towers for urban yards and small spaces, and even worm composters that will make fast, odorless work of all your table scraps in the space under your kitchen sink. Select the bin style that works for you, and install it near the garden, away from your house.
Once you have reached a critical mass of scraps in your bin (usually about a cubic yard of material or a 3’x3’x3′ pile), it will begin to noticeably break down. After everything has decomposed and transformed into dark, rich-smelling, crumbly humus (see picture above), you can sprinkle it around your trees, lawn, garden or houseplants to help them grow.
Considered “black gold” by most gardeners, even if you don’t garden yourself, you could easily give your compost away to your neighborhood green thumb! She’d be so grateful. Avid gardeners never seem to have enough compost.
100 Things You Can Compost
The basics of composting are simple. Almost anything natural or plant-based can be composted; just don’t add meat or a lot of fat, because as they decompose, they will create a smell that will bring every critter for miles to your yard!
Always remember that an effective compost pile is a careful balance of dry or brown things that contain carbon (like leaves or paper) and wet or green things that contain nitrogen (like food scraps or rabbit droppings). So, for example, if you add a lot of shredded paper or cardboard to the pile, you will need to balance it with a nice heap of fresh grass clippings or horse manure, and probably some water from the hose so things don’t get too dry.
And, don’t forget that the smaller you can shred or chop your compostable items before you put them into the pile, the faster and more evenly they will decompose. It’s really worth the extra effort to chop and shred if you plan to use your compost for vegetable gardening, or, simply compost tough, slow things like tree branches and old rope in a separate pile.
The following list is meant to get you thinking about your compost possibilities. Imagine how much trash we could prevent from going into the landfills if each of us just decided to compost a few more things!
