Create a Compost Pile

Turn your waste into something useful

Whether your garden consists of small containers on your deck or raised beds in the yard, every gardener should be knowledgeable about organic composting material. Compost soil, the “black gold” that is created from decomposing organic material, acts as nutrition for the plants. Think of it like a vitamin: Plants grown in soil with added compost perform better. Composting can benefit the environment as well. Removing table scraps, coffee grounds and other organic material from your garbage will reduce landfill material. Lucky for you, setting up a compost station in your yard is easy and inexpensive.

Best ingredients for your compost

Green Materials
Nutrient-rich green materials such as grass clippings, flowers, discarded vegetables, fruit rinds and plant-based food scraps. Never use animal proteins or bones. (See full list above.)

Brown Materials
Carbon-rich brown materials like dried leaves, branches, straw, newspaper and wood chips. (See full list above.)

You’ll water the layers to add moisture for breaking down the ingredients.

Garden Soil
Your existing garden soil is fine to use.

Animal manure
This is optional. Despite appearing brown, animal manure (from herbivores only) is very high in “green” nitrogen-rich materials and serves as an excellent natural fertilizer for plants. Many local zoos actually sell zoo poo: a mixture of elephant, zebra or other plant-eating animal manure local gardeners swear by. Never use manure from meat-eating animals.

How to create the best compost pile

Layer your ingredients in the following manner:

  1. Add several inches of the dry brown material to the bottom of the pile.
  2. Add several inches of the moist, green material on top of the brown material.
  3. Add a thin layer of soil.
  4. Water this first layer until it is wet but not soggy.
  5. Repeat the layering of dry, wet, soil, water in that order. The dry material will help drain the moisture; the wet material will activate the decomposition process.
  6. If you add animal manure, add it with your other green material.
  7. Every couple of weeks turn the pile with a pitchfork or shovel, mixing the layers and bringing material from the outer edges inward. The pile should generate heat, and eventually you should start to see earthworms in your pile.
  8. The “black gold” or dark soil that is created can be removed and mixed into your existing containers and vegetable gardens. Always add compost to existing soil.

Establishing your compost pile

There are several different ways to set up your compost pile. Ideally your compost will sit directly on soil so that organisms, like worms, can have access to your compost pile and assist with the breakdown process (and add valuable nutrients in the process). See the list below for the pros and cons of each method of composting.

Sheet composting
Sheet composting is very easy and works well in small spaces. In an unused area of your soil, dig a trench about 1 foot deep. Add your organic compost ingredients and cover with a layer of soil. Over time this material will break down and create a trench filled with compost-rich soil.
Pros: Easy, fast, inexpensive. This is also a great way to break down large amounts of one type of material, like a large pile of leaves or grass clippings.
Cons: Subject to pests and pets.

Open composting
Create a 3-foot-by-3-foot area in your yard and add your compost materials directly onto the soil. For easy mixing, some gardeners choose to create a short, walled barrier to contain the mixture, but this is not necessary. After layering your mixture, you can cover the materials with a tarp. This will keep the odors in, the rain out and add heat for the activation process.
Pros: Easy, inexpensive, allows you to create several piles in your yard
Cons: Pets and pests could easily get into the pile. If not covered, too much rain can saturate the mixture, odors may escape, and it could be unsightly.

Compost bins
There are many compost bins on the market today. Make sure that your compost bin is designed for easy mixing, good oxygen circulation, drainage and retrieval of the compost soil. Look for one that has a tumbling mechanism — this will be the easiest way to thoroughly mix the ingredients and distribute them for better activation.
Pros: The self-contained bins protect your compost from unwanted pests, odor and rain, making it a great choice for climates with seasonal changes. The enclosed bin generates more heat and will therefore create soil faster than an open method.
Cons: Cost is really the only downside to this method. Bins range in price from $100 on the low end to over $300 for a high-quality model.

Other tips:

Keep your compost balanced
The healthiest ratio for your compost pile is composed of more carbon than nitrogen. Balance your compost pile with 2/3 brown, carbon-rich materials and 1/3 green, nitrogen-rich materials. According to Earth Easy, “The bulkiness of the brown materials allows oxygen to penetrate and nourish the organisms that reside there. Too much nitrogen makes for a dense, smelly, slowly decomposing anaerobic mass.”

Keep your compost hot
Maintaining the right temperature for your compost pile does several things. First, it helps break down the organic materials in an efficient manner. Second, with the right temperature your compost will kill unwanted items such as weed seeds. The middle of the pile should be about 130-150 degrees. It takes 30 days at 140 degrees to kill weed seeds.
