Why Composting?

Before diving into the “how-to,” it’s essential to understand why composting is beneficial. Composting acts like nature’s recycling system. It helps you reduce waste, enrich your soil, and even save money.

Environmental Benefits

Composting reduces the amount of waste that ends up in landfills, cutting down on greenhouse gas emissions. When organic material decomposes anaerobically (without oxygen) in a landfill, it produces methane—a potent greenhouse gas. By composting, you help minimize this harmful gas.

Economic Benefits

With compost, you reduce the need for chemical fertilizers, saving money and avoiding potential soil and water contamination. Composting also reduces the garbage you send to the landfill, which might reduce your trash collection fees if you’re charged by volume.

Soil Health

Compost enriches soil by aiding with moisture retention, fostering beneficial bacteria and fungi, and adding essential nutrients. Healthier soil translates to healthier plants.

Choosing Your Compost Bin

Choosing the right compost bin is the first step to effective composting. The kind of bin you choose depends on the amount of compost you expect to produce and the space you have available.

Types of Compost Bins

Here’s a detailed table to help you choose the right compost bin:

Type of Bin	Ideal For	Pros	Cons
Compost Pile	Large gardens	Easy to start, inexpensive	Requires a lot of space, can be untidy
Tumbling Bin	Small-to-medium gardens	Easy to turn, pest-resistant	Can be expensive, limited capacity
Stationary Bin	Medium-to-large gardens	Large capacity, can be inexpensive, neat	Harder to turn, pests can be an issue
Worm Bin	Indoor/Apartment composting	Great for small spaces, produces rich compost	Needs more maintenance, initial investment cost

Building Your Compost Bin

Once you’ve chosen your bin type, the next step is building it. Here, you’ll find how to construct each kind.

Building a Compost Pile

If you have plenty of yard space, a compost pile might be the simplest and most cost-effective option.

Choose a Location: Pick a shady spot that’s accessible but not too close to your house. The shade helps retain moisture.
Prepare the Ground: Loosen the soil to improve aeration and drainage.
Layering: Start with a layer of coarse materials like twigs or straw. Follow this with alternating layers of greens (nitrogen-rich materials like kitchen scraps) and browns (carbon-rich materials like dried leaves).

Building a Tumbling Bin

Tumbling bins are excellent for those who prefer a tidier solution.

Purchase a Bin: Choose one that suits your garden size and budget.
Location: Place it in a spot that gets some sun but not all day.
Assembly: Follow the manufacturer’s instructions for assembly. Usually, it’s a straightforward process involving some screws and handles.
Layering: Add your green and brown materials as needed, and start tumbling every few days.

Building a Stationary Bin

Stationary bins offer a middle ground between compost piles and tumbling bins.

Choose Your Materials: You can make a bin from wood, wire mesh, or purchased plastic bins.
Location: Like other bins, choose a shady but accessible area.
Construction: Assemble the bin according to your material. If using wood, make sure it’s untreated to avoid toxic chemicals leaching into the compost.
Layering: Add your compost materials in alternating layers of greens and browns.

Building a Worm Bin

Perfect for small spaces and indoors, worm bins are unique but effective.

Purchase or Build a Bin: Plastic bins with tight-fitting lids work well.
Add Bedding: Use shredded paper, cardboard, or coconut coir. Moisten but don’t soak it.
Add Worms: Red wigglers are the most effective composting worms.
Feeding: Add small amounts of kitchen scraps. Avoid meat and dairy products.

What Goes Into the Compost Bin?

Understanding what you can and cannot compost is crucial to producing high-quality compost.

Green vs. Brown Materials

Composting is all about a balance of green and brown materials.

Greens (Nitrogen-Rich)	Browns (Carbon-Rich)
Fruit and vegetable scraps	Dead leaves
Coffee grounds and filters	Straw/Hay
Grass clippings	Cardboard
Tea bags (non-synthetic)	Shredded paper
Plant trimmings	Wood chips
Eggshells (crushed)	Sawdust

Materials to Avoid

Not everything decomposes well. Here’s what to avoid:

Meat and dairy products (attract pests)
Oils and fats (slow to decompose, attract pests)
Diseased plants (potential to spread disease)
Pet waste (potential health risks)
Treated wood (contains harmful chemicals)

Maintaining Your Compost Bin

Once your bin is set up and filled, the next step is maintenance. Proper maintenance ensures that your compost decomposes efficiently.

Aeration

Turning your compost provides necessary aeration, speeding up the decomposition process.

Compost Pile: Use a pitchfork or shovel to turn the pile every few weeks.
Tumbling Bin: Rotate the bin a few times every couple of days.
Stationary Bin and Worm Bin: Aerate gently to not disturb the worms too much if you’re using a worm bin.

Moisture Control

Your compost should be as moist as a wrung-out sponge.

Too Dry: Add water and more green materials.
Too Wet: Add brown materials like straw or leaves.

Temperature

Compost heats up as it decomposes. A temperature of 135-160°F is ideal for killing off pests and pathogens.

Monitor Temperature: Use a compost thermometer to ensure it’s hot enough but not overheating.
Adjusting: If it gets too hot, aerate more frequently. If it’s too cool, add more greens and ensure adequate aeration.

Pest Control

Cover Food Scraps: Always cover fresh food scraps with a layer of browns.
Use a Lid: Securely close tumbling or worm bins to keep pests out.
Traps: For stationary bins, surrounding the base with wire mesh can deter critters.

Harvesting Your Compost

After several months (or even weeks for hot composting), you’ll have rich, dark compost.

How to Know When It’s Ready

Finished compost is dark, crumbly, and smells earthy.

Check Consistency: You shouldn’t be able to recognize any of the original materials.
Smell: The finished compost should have a pleasant, earthy smell.

How to Harvest

From a Pile: Use a shovel to remove the bottom, most decomposed layer.
From a Tumbling Bin: Open the compartment and empty it out.
From a Stationary Bin: Often, these have doors or slots at the bottom for easy access.
From a Worm Bin: Push contents to one side, add new bedding to the empty side, and after the worms migrate, harvest the compost.

Using Your Compost

Once harvested, your compost is ready to use in various ways.

Soil Amendment

Preparation: Mix the compost with your garden soil to improve its texture and fertility.
Ratio: A good rule is to mix one part compost with three parts soil.

Mulch

Compost can also act as mulch, helping to retain soil moisture and suppress weeds.

Application: Spread a 2-3 inch layer of compost around your plants.
Timing: Apply in the spring and fall for the best results.

Compost Tea

You can even make compost tea for your garden.

Recipe: Place a shovel full of compost into a container, add water, and let it sit for a few days. Stir occasionally.
Application: Use the liquid to water your plants, providing them with a nutrient-rich boost.

Troubleshooting Common Issues

Even with the best care, you might encounter some issues. Here’s how to handle them:

Odor Problems

Bad smells usually mean too much nitrogen or that the pile is too wet.

Solution: Add more brown materials and turn the pile to introduce more air.

Slow Decomposition

If your compost isn’t breaking down, it might be too dry, lack nitrogen, or need more aeration.

Solution: Moisten if dry, add more green materials, and turn more frequently.

Pests in the Bin

If you notice pests like rats or flies, you might be composting unsuitable materials or not covering your scraps properly.

Solution: Avoid composting meat or dairy and always cover new additions with browns.

Excessive Dryness or Wetness

Monitor moisture closely. Too dry, and decomposition slows down. Too wet, and it becomes a smelly, sludgy mess.

Solution: Add water to dry compost and mix in dry, brown materials to wet compost.

Benefits of Ongoing Composting

Maintaining a compost bin might seem tedious, but the long-term benefits are well worth it.

Sustainable Living

Composting is a practical step toward a more sustainable lifestyle.

Reduce Waste: Less kitchen and yard waste heading to the landfill.
Eco-friendly Gardening: Less reliance on chemical fertilizers.

Economic and Health Benefits

Beyond environmental gains, composting saves money and fosters a healthier garden.

Save Money: Reduced need for store-bought fertilizers.
Healthier Plants: Nutrient-rich soil supports robust plant growth, providing you with healthier fruits and vegetables.

Personal Satisfaction

There’s an intangible satisfaction that comes from composting. It connects you to the natural life cycle and gives you a sense of accomplishment.

Educational: Gain a better understanding of natural processes.
Rewarding: See the fruits of your labor in the form of a thriving garden.
