Sustainable Gardening: Composting Made Easy

Article Posted By: Home Depot Staff

Getting started with composting is much easier than many people think. Making your own compost is one of the best things you can do for your garden. Barring the purchase of your composter or the materials to make one, the resulting fertilizer and soil amendment is 100% free.

Composting is a natural biological process that converts organic material into humus-like matter that gardeners refer to as “black gold.”

You can make your own backyard compost container from welded wire mesh, concrete blocks or wooden shipping pallets—anything in which you can form a pile of compost material that’s roughly 3–5 feet across and no higher than 5 feet.

If you prefer to buy a bin, consider one with features that make turning the contents easier, thus speeding up the decomposing process. The Home Depot carries compost bins of all different sorts and sizes.  Be sure to think about getting a kitchen compost collector to help you keep the kitchen scraps from making a mess.

Here are the five easy to follow steps to getting started with composting:

1. Mix it

Place the bin near your garden and back door. A small indoor bin is handy to use along with the larger one outdoors. Throw scraps into the indoor bin and, as it fills up, empty it periodically into the outdoor one. Compostable items such as kitchen scraps, tea bags, coffee grinds and grass clippings can be added to the bin; so can brown materials such as dried leaves, sawdust, straw, wood ash and the woody stalks of plants.


2. Layer it

Layer materials high in carbon, including lawn clippings, chopped leaves, green plants and agricultural crop residues with materials high in nitrogen, such as manure, alfalfa meal, hay, paper products, sewage sludge and wood. Just about any organic material can be added to the bin, including food scraps, eggshells, tea leaves and coffee grounds. Never add chemically treated wood, diseased plants, human or pet waste, meat, bones, fatty foods or weeds. Add water regularly during the compost-building process to help get rid of air pockets.


3. Turn it

You can begin to make compost in as little as a few weeks if you speed up the process by turning the pile with a pitchfork once a week and adding fresh manure. Mixing it allows oxygen into the center of the pile, encouraging the growth of bacteria and fungi, which break down organic material into simpler substances. Regularly turned organic matter will become finished compost in 4–8 months.


4. Break it down

Compost is ready to be used when it is dark and crumbly and has an earthy smell. You can sift it to separate material that hasn’t finished composting, but those pieces will continue to decompose in your garden. The smaller the pieces, the faster they will break down.


5. Spread it

Once it’s ready, work the compost into the soil to give it an organic boost before planting. Spread it on the soil’s surface as mulch on flower beds and around the base of landscape plants. Compost may also be used as a top dressing for lawns or as an ingredient in potting mixes.


Your plants, lawn and trees will love you for this…happy composting!
