Ready to create a compost pile? There are as many ways to create a compost pile as there are gardeners. You can create a free-standing compost heap, which is literally a mound or pile (preferably out of sight). If you’d prefer a ready-made one, you can buy a compost bin — there are many styles to choose from. Another option is to build your own bin out of lumber (recycled wooden pallets work great) and wire-mesh fencing.
The Ingredient Layers
Any material that was once a plant, from asparagus trimmings to autumn leaves, can be composted. Most households generate a steady stream of compost materials from the kitchen, garden, and landscape. Begin layering organic materials such as leaves, straw, old corn stalks, weed-free and pesticide-free grass clippings, eggshells, coffee grounds, tea, fruit peels, and other organic matter from the kitchen; just avoid meats, greasy ingredients, and pet droppings. If most of the compost materials at your house come from your kitchen, consider using an enclosed, or stationary, composter. In addition to keeping the compost hidden from view, stationary composters discourage unwanted visits from animals.
The bigger your garden, the more you will need a good place to compost its waste. An open pile that can be chopped and turned quickly works well for composting garden waste. Leaves need to weather for a while before they decompose, so it is often best to stockpile them in a bin through the winter. In spring, the weathered leaves can be used as mulch, or you can combine them with kitchen and garden waste to help them decompose a little faster. Some gardeners chop leaves with a mulching mower or leaf shredder to speed decomposition.
If you’re starting a new pile, sprinkle it with a couple of shovelfuls of topsoil or previously composted materials to add the needed microorganisms for decomposition. A sprinkle of organic fertilizer (such as blood meal or feather meal) adds nitrogen that will help increase the rate of decomposition as well.
If you are creating an open-air pile, continue layering these items (according to the guidelines below) until your mix is 3 to 4 feet tall. Water between layers, but don’t make the pile soggy. If you put your materials in a purchased compost tumbler, just add and tumble.
Balancing Browns and Greens
There is no precise recipe or formula to create a compost pile beyond the simple ratio of 3 parts “browns” to 1 part “greens.” As shown in the list below, most “browns” come from trees, and they are rich in carbon (often abbreviated as C in composting lingo). “Greens” come from fresher, juicier materials, like garden and kitchen waste, but any ingredient that is rich in nitrogen (N) qualifies as a green.
Every gardener has plenty of greens in summer, followed by an abundant supply of browns in the fall. To make it fast and convenient to balance your compost, save up shredded leaves and pine needles in the fall, and store them in trash bags, an old garbage can, or a large wire pen. In summer, should watermelon rinds and spent plants overload your compost with greens, layering on some leaves will set things to right. Composters who live in areas where leaves are scarce often use shredded newspaper to keep summer compost from going gloppy with too many greens.
If your garden is small yet your yard has many trees, your compost may need additional greens to balance all the browns from collected leaves. Grass clippings from lawns that have not been treated with herbicides will give fast results when mixed into a stalled leaf-based compost, or you can energize it with high-nitrogen plant meals like alfalfa, canola, or cottonseed meal. When sprinkled in among layers or mixed in well, organic fertilizers made from poultry manure provide nitrogen for compost, too.
When made of 3 parts “browns” and 1 part “greens,” any compost will make good progress.
Serious composters often have multiple bins in various stages of composting so that one is always ready.
If you turn the pile, it will decompose more evenly and quickly. Invest in a good-quality turning fork to make easy work of reaching into the pile to mix the ingredients. Here, garden writer Barbara Pleasant turns her compost pile.
- Leaves are often the easiest, cleanest, and most readily available ingredient for compost. These are whole, but you may also chop them with a mulching mower first; they will make compost faster.
A tumbler composter makes fast work of turning compost and keeps it away from critters.
Set up conveniently located pens to collect leaves for composting in the fall. These compost bins are made from hardware cloth.
Some gardeners sift their compost before adding it to the garden soil. This is a laborious task, but it creates very fine, completely decomposed compost that won’t tie up nutrients in the soil.
