Getting Started with Composting

Composting is an easy way to recycle organic waste and create nutrient-rich soil for your garden. By following a few simple steps, you can successfully start composting in Eugene, Oregon.

Choosing a Composting Method

Backyard composting is a popular method for Eugene residents. It allows for easy management of food scraps and yard debris. Another option is vermicomposting, which uses worms to break down organic matter.

For those with limited space, a compost tumbler can be an effective solution. This method accelerates decomposition by allowing frequent turning of the compost.

Compost Bin Options and Setup

A rodent-proof compost bin with a tight-fitting lid is recommended for backyard composting. Place the bin in a convenient outdoor location, at least 10 feet away from property lines.

Commercial bins are available, or you can build your own using wood or wire mesh. Ensure proper airflow and drainage in your chosen design.

For vermicomposting, use a shallow bin with drainage holes. Place it in a cool, dark area indoors or in a shaded outdoor spot.

Materials for Composting

Composting requires a balance of “brown” and “green” materials. Browns include:

  • Dry leaves
  • Wood chips
  • Sawdust
  • Straw

Greens consist of:

  • Food scraps (fruits, vegetables)
  • Coffee grounds
  • Grass clippings

Layer these materials, starting with browns at the bottom. Add water to keep the pile moist but not soggy. Avoid meat, dairy, and oily foods to prevent odors and pests.

Turn the compost regularly to aerate it and speed up decomposition. With proper care, your compost will be ready to use in 3-6 months.

Successful composting requires the right mix of materials and regular upkeep. Proper selection of organic matter and maintenance practices ensure a healthy, productive compost pile.

What to Compost

Composting thrives on a balance of “green” and “brown” materials. Green materials are nitrogen-rich and include:

  • Fresh grass clippings
  • Fruit and vegetable scraps
  • Coffee grounds and tea bags
  • Eggshells (crushed)
  • Plant trimmings

Brown materials provide carbon and include:

  • Dry leaves
  • Straw or hay
  • Sawdust (untreated wood)
  • Shredded paper or cardboard
  • Wood chips

Aim for a ratio of about 3 parts brown to 1 part green materials. This balance helps create ideal conditions for decomposition.

Items to Exclude from Your Compost

Some items can harm your compost or attract pests. Avoid adding:

  • Meat, fish, or dairy products
  • Oils or fatty foods
  • Diseased plants
  • Weeds with mature seeds
  • Pet waste
  • Treated lumber or sawdust
  • Plastic bags or rubber objects

These materials can introduce harmful bacteria, slow decomposition, or contaminate the compost with chemicals.

Maintaining Your Compost Pile

Regular maintenance keeps the composting process active and efficient. Key practices include:


  1. Turning the pile: Mix materials every 1-2 weeks to aerate and distribute moisture.



  2. Monitoring moisture: The pile should feel like a wrung-out sponge. Add water if too dry, or dry materials if too wet.



  3. Chopping materials: Smaller pieces decompose faster. Aim for pieces no larger than 6 inches.



  4. Balancing ingredients: Maintain the green-to-brown ratio as you add new materials.



  5. Covering the pile: Use a tarp or lid to retain heat and moisture.


With proper care, a compost pile can produce rich, nutrient-dense soil amendment in 3-6 months.

Optimizing Your Compost

Creating an effective compost pile requires balancing key elements and maintaining optimal conditions. Proper management of materials, moisture, and aeration will accelerate decomposition and produce high-quality compost.

Balancing Browns and Greens

A successful compost pile needs the right mix of carbon-rich “browns” and nitrogen-rich “greens.” Browns include dry leaves, straw, wood chips, and sawdust. Greens consist of food scraps, grass clippings, and coffee grounds.

Aim for a ratio of about 3 parts browns to 1 part greens by volume. This balance provides the ideal carbon-to-nitrogen ratio for microorganisms to thrive and break down organic matter efficiently.

Too many browns can slow decomposition, while excess greens may create odors and attract pests. Adjust the mix as needed to maintain a productive compost pile.

Aeration and Moisture Levels

Proper aeration and moisture are crucial for composting microorganisms. Oxygen fuels decomposition, while water facilitates nutrient transport and microbial activity.

To ensure adequate airflow:

  • Use coarse materials like twigs or wood chips at the bottom of the pile
  • Turn the pile regularly to incorporate oxygen
  • Consider using a compost aerator tool

Maintain moisture levels similar to a wrung-out sponge. The pile should feel damp but not soggy. Add water if the pile becomes too dry, or mix in dry browns if it’s overly wet.

Turning and Temperature

Regular turning accelerates decomposition by redistributing moisture, heat, and microorganisms throughout the pile. Turn your compost every 1-2 weeks for faster results.

Monitor the pile’s temperature:

  • Active compost should feel warm to the touch
  • Ideal temperature range: 130-150°F (54-66°C)
  • Use a compost thermometer for precise readings

If the pile isn’t heating up, add more greens or water. If it’s too hot, turn it more frequently to release excess heat. As decomposition slows, the pile will naturally cool and mature into finished compost.

Using Your Compost

Compost is a versatile and valuable resource for enhancing soil health and supporting plant growth. It can be applied in various ways to improve gardens, lawns, and landscaping.

Compost as Soil Amendment

Nutrient-rich compost acts as an excellent soil amendment, improving soil structure and fertility. Mix compost into garden beds before planting to enhance soil quality. For established plants, gently work compost into the top few inches of soil around their base.

In vegetable gardens, incorporate 2-3 inches of compost into the top 6-8 inches of soil. This practice boosts nutrient content and water retention.

For lawns, apply a thin layer (¼ to ½ inch) of screened compost and rake it in. This technique, known as topdressing, can help improve soil structure and promote healthier turf.

Mulching with Compost

Compost makes an effective mulch for landscape areas and garden beds. Apply a 2-3 inch layer around plants, trees, and shrubs. Keep the mulch a few inches away from plant stems to prevent rot.

Compost mulch helps retain soil moisture, regulate soil temperature, and suppress weed growth. As it breaks down, it slowly releases nutrients into the soil.

In vegetable gardens, use compost as a side dressing. Apply a thin layer around plants during the growing season to provide a steady supply of nutrients.

Compost in Gardening

Compost plays a crucial role in organic gardening practices. Use it to create potting mixes for container plants by blending equal parts compost, sand, and garden soil.

For seed starting, mix compost with vermiculite or perlite to create a nutrient-rich growing medium. Use a ratio of 1 part compost to 3 parts vermiculite or perlite.

Compost tea, made by steeping compost in water, serves as a natural liquid fertilizer. Apply it to plant leaves or soil to boost nutrient uptake and promote plant health.

In raised beds, mix compost with native soil at a 1:1 ratio to create an ideal growing environment for vegetables and flowers.

Challenges and Solutions

Composting in Eugene, Oregon presents unique obstacles, but effective strategies exist to overcome them. Proper techniques and knowledge can transform common issues into opportunities for successful composting.

Common Compost Mistakes

Many composters add too many “green” materials like food scraps without enough “brown” materials like leaves or wood chips. This imbalance can lead to odors and slow decomposition. To fix this, maintain a 3:1 ratio of browns to greens.

Another mistake is inadequate moisture. Compost should be as damp as a wrung-out sponge. If it’s too dry, add water. If too wet, mix in dry brown materials.

Improper aeration can also hinder the process. Turn the pile regularly to introduce oxygen, which speeds up decomposition and prevents methane production.

Troubleshooting Compost Problems

Odors often indicate an imbalance. A rotten egg smell suggests too much moisture and not enough air. Add browns and turn the pile. An ammonia smell means too much nitrogen. Add more carbon-rich materials.

Pests can be deterred by burying food scraps in the center of the pile and using a rodent-proof bin with a tight-fitting lid. Place bins at least 10 feet from property lines.

Slow decomposition may result from insufficient moisture or a lack of nitrogen. Add water or green materials as needed. In colder months, insulate the bin to maintain heat.

Composting in Urban Agriculture

Space constraints in urban settings can limit composting options. Use compact systems like tumblers or stacked bins for small yards or balconies. These also help control odors and pests.

For apartment dwellers, indoor vermicomposting with worms is an effective solution. It produces nutrient-rich compost in a small space without odors.

Community gardens often offer shared composting facilities. These provide a way for urban residents to compost food waste even without personal outdoor space. Check with local urban agriculture programs for opportunities.

Partnering with neighbors can create a collective composting system, sharing resources and labor while building community connections around sustainable practices.
