How Do I Make Compost From Kitchen Scraps?

“Hey, I recently moved to a house with a sizable backyard in the suburbs of Vancouver, Canada. I’ve always been passionate about gardening and sustainable living, and I’m looking to get into composting to help enhance my soil quality and reduce kitchen waste. Could you guide me on how to make compost from kitchen scraps and what I need to consider throughout the process?” Sincerely, Hannah, Vancouver, Canada.

How Do I Make Compost From Kitchen Scraps?

Absolutely, Hannah! Turning kitchen scraps into compost is a fantastic way to enrich your garden soil and minimize waste. Let’s break down the process into simple steps to get you started.

Understanding Composting

Composting is a natural process where organic materials, like kitchen scraps, decompose into a nutrient-rich soil amendment. It’s vital for recycling nutrients back into the earth, enhancing soil structure, and promoting healthy plant growth.

Why Compost Kitchen Scraps?

There are a few compelling reasons to start composting your kitchen scraps:

• Reduces Landfill Waste: Composting helps divert organic waste from landfills, reducing methane emissions and contributing to a healthier planet.
• Enriches Soil: Compost improves soil structure, increases moisture retention, and introduces beneficial microorganisms.
• Cost-Effective: Homemade compost can reduce the need for store-bought fertilizers and soil conditioners.

Materials Needed for Composting

To start composting, gather the following materials:

• Compost Bin: You can purchase a compost bin or build one using wood pallets or chicken wire. Ensure it has good ventilation and drainage.
• Kitchen Scraps: Collect vegetable peels, fruit scraps, coffee grounds, tea bags, eggshells, and other organic kitchen waste.
• Browns: These are carbon-rich materials like dry leaves, cardboard, paper, and straw.
• Greens: Nitrogen-rich materials such as grass clippings, green leaves, and kitchen scraps.
• Water: Moisture is crucial for the composting process. Keep your compost pile damp but not waterlogged.
• Compost Turner: A garden fork or compost turner helps mix and aerate the compost.

Balancing Greens and Browns

The success of your compost largely depends on the right balance between greens and browns:

• Greens: These are materials that add nitrogen to your pile. Ideal green materials include kitchen scraps, coffee grounds, tea bags, and fresh garden clippings.
• Browns: These materials add carbon. Common browns include dry leaves, cardboard, straw, and newspaper.

Maintain a balance of roughly 3:1 browns to greens. Too much nitrogen (greens) can make your compost pile smell, while too much carbon (browns) can slow down the decomposition process.

Steps to Create Compost from Kitchen Scraps

1. Choosing a Location: Find a spot in your backyard that is well-drained and receives partial sunlight. Avoid areas that are completely shaded or exposed to extreme weather conditions.
2. Setting Up the Bin: If using a compost bin, place it directly on the soil to allow worms and other beneficial organisms easy access. Ensure the bin has adequate ventilation and drainage holes.
3. Layering Materials: Start by adding a layer of coarse materials like straw or garden clippings. Alternate between layers of greens (kitchen scraps, fresh garden waste) and browns (dry leaves, cardboard).
4. Maintaining Moisture: Aim to keep your compost pile as damp as a wrung-out sponge. Add water if the compost is dry, and turn it more frequently if it’s too wet.
5. Aerating the Pile: Turn your compost pile regularly, ideally once a week, to introduce oxygen. This helps speed up the decomposition process and prevents foul odors.
6. Monitoring the Temperature: A healthy compost pile will heat up as microorganisms break down the materials. The ideal temperature range is 135-160°F (57-71°C). If it drops below this range, add more greens and turn the pile.
7. Harvesting the Compost: In a few months, the compost should turn into dark, crumbly soil with a pleasant earthy smell. Sift through the compost to remove any undecomposed materials and add the finished product to your garden beds.

Avoiding Common Mistakes

Here are some pitfalls to avoid, Hannah:

• Adding Meat or Dairy: Avoid putting meat, dairy, or oily foods in your compost pile. These can attract pests and create unpleasant odors.
• Too Many Citrus Peels: While citrus peels are compostable, too many can make your compost pile too acidic. Add them sparingly.
• Neglecting the Pile: Regular attention is key. Turn the pile frequently and monitor moisture levels to keep the decomposition process active.

Benefits of Using Compost in Your Garden

Using compost not only improves soil health but also provides an array of benefits for your garden:

• Increases Soil Fertility: Compost is rich in nutrients that are slowly released into the soil, providing a steady supply for your plants.
• Enhances Soil Structure: Compost helps soil particles bind together, creating a structure that holds moisture and nutrients while allowing excess water to drain away.
• Encourages Beneficial Microorganisms: Healthy compost adds microorganisms that help break down organic matter and suppress plant diseases.
• Reduces Need for Chemical Fertilizers: With high-quality compost, you can reduce or even eliminate your reliance on chemical fertilizers, making your garden more eco-friendly.

Advanced Composting Tips

To take your composting to the next level, consider these advanced tips:

• Composting with Worms (Vermicomposting): Worms, especially red wigglers, can break down kitchen waste even faster and produce nutrient-rich worm castings. This method is excellent for those with limited space.
• Maintaining a Compost Thermometer: Using a compost thermometer helps monitor the temperature accurately, ensuring your compost pile stays in the optimal range for decomposition.
• Curing Compost: After the active composting phase, allow the compost to “cure” for a month or two. This resting period helps stabilize the compost, making it safer for plants.
• Composting In Winter: In colder climates, insulate your compost pile with straw or move it to a sunnier spot to keep it active during winter months.

Sustainability and Environmental Impact

Composting is an integral part of sustainable living. Here’s how it contributes to environmental health:

• Reduces Carbon Footprint: Composting reduces methane emissions from landfills, lowering the overall greenhouse gas emissions.
• Promotes Soil Health: Healthy soil rich in organic matter is better at retaining water, reducing the need for irrigation and decreasing soil erosion.
• Saves Waste Disposal Costs: By composting, you reduce the volume of household waste, which can lower municipal waste disposal costs.

Frequently Asked Questions

Here are some common questions you might have, Hannah, as you embark on your composting journey:

How long does it take to make compost?

Depending on factors like material types, pile size, and how frequently it’s turned, compost can take anywhere from 3 months to a year to become finished.

Can I compost all my kitchen scraps?

You can compost most kitchen scraps, but avoid meat, dairy, oily foods, and large volumes of citrus peels. These materials can create odor issues and attract pests.

Why does my compost smell bad?

A foul smell usually indicates a lack of oxygen or an imbalance of greens and browns. Turn the pile to aerate it and add more browns to balance excess nitrogen.

Can I compost in a small garden or apartment?

Yes! Vermicomposting with worms or using a small indoor compost bin can work well in limited spaces.

Happy composting, Hannah! You’ll find that creating your nutrient-rich compost is both rewarding and beneficial for your garden.

Final Thoughts…

Hannah, thank you for your question about making compost from kitchen scraps. Remember, the key components are balancing greens and browns, maintaining moisture, and regularly turning your pile. You’ll not only enhance your garden soil but also contribute to a healthier planet.

Enjoy the process and soon enough, your garden will thank you!
