Composting offers Hillsboro residents an effective way to reduce waste and contribute to sustainability efforts. This eco-friendly practice transforms organic materials into nutrient-rich soil, benefiting gardens and the environment.

Hillsboro community members with yard debris collection service can add food scraps to their yard debris roll cart, making composting even more convenient. This curbside compost collection allows for a wide range of materials, including yard waste, fruits, vegetables, meat, bones, and dairy products.

Successful composting in Hillsboro involves a balance of “brown” materials high in carbon, such as fall leaves, and “green” materials high in nitrogen, like grass clippings and food scraps. By following proper composting techniques, residents can create valuable soil amendments while diverting organic waste from landfills.

Benefits of Composting

Composting offers numerous advantages for gardeners and environmentally-conscious individuals in Hillsboro, OR. This natural process transforms organic waste into a valuable resource, benefiting both plants and the ecosystem.

Nutrient-Rich Soil Enhancement

Compost acts as a natural fertilizer, enriching soil with essential nutrients. It releases these nutrients slowly, providing a steady supply for plant growth over time. This organic material improves soil fertility, reducing the need for chemical fertilizers.

Compost contains a diverse array of micronutrients often lacking in synthetic fertilizers. These elements support robust plant development and increase resistance to pests and diseases. Gardeners in Hillsboro can use compost as a top dressing for lawns or mix it into garden soil to boost plant health.

The nutrient-rich nature of compost also enhances water retention in soil. This property helps plants better withstand dry spells, reducing the frequency of watering needed in Hillsboro gardens.

Waste Reduction and Sustainability

Composting significantly reduces household waste sent to landfills. By diverting organic materials from the waste stream, Hillsboro residents can decrease their environmental impact. This practice aligns with the city’s sustainability goals and helps conserve landfill space.

Food scraps and yard debris compose a large portion of typical household waste. Composting these materials at home reduces garbage collection needs and associated costs. It also lowers methane emissions from landfills, as organic matter decomposes differently in compost piles.

Hillsboro’s residential food composting program further supports this effort. It allows residents to place clean food scraps in yard debris bins, expanding composting beyond individual households.

Improvement of Soil Structure

Compost enhances soil structure, creating a more favorable environment for plant roots. It increases soil porosity, allowing better air and water circulation. This improved structure supports healthier root systems and more vigorous plant growth.

Sandy soils benefit from compost’s ability to retain moisture and nutrients. In clay soils, compost improves drainage and prevents compaction. These improvements make garden soil in Hillsboro more resilient and productive across various plant types.

Compost also boosts soil’s capacity to hold water. This reduces runoff and erosion, particularly beneficial in Hillsboro’s rainy seasons. Enhanced water retention means less frequent watering for gardens and lawns, conserving water resources.

What Can Be Composted

Composting allows you to recycle a wide variety of organic materials. The key is balancing “green” nitrogen-rich materials with “brown” carbon-rich materials. Food scraps, yard debris, and other organics can all contribute to a healthy compost pile.

Greens as Nitrogen Sources

Grass clippings provide an excellent nitrogen source for compost. Add them in thin layers to prevent matting. Vegetable and fruit scraps from the kitchen are also nitrogen-rich. Coffee grounds contribute nitrogen and improve soil structure. Other green materials include:

• Fresh plant trimmings
• Weeds (without seeds)
• Tea bags
• Eggshells

Avoid adding too many greens at once, as this can lead to odors. Aim for a mix of 1 part greens to 3 parts browns.

Browns as Carbon Sources

Brown materials provide carbon and help aerate the compost pile. Dry leaves are an abundant carbon source in fall. Shredded newspaper and cardboard work well too. Other brown materials include:

• Straw or hay
• Wood chips
• Sawdust
• Pine needles
• Corn stalks

These materials break down slowly, providing structure to the compost. Alternate layers of browns and greens for best results.

Acceptable Food Waste

Many food scraps can be composted, reducing household waste. Fruit and vegetable scraps are ideal. Eggshells add calcium to the finished compost. Coffee grounds and tea bags are also compostable. Other acceptable food waste includes:

• Bread and grains
• Nutshells
• Used paper napkins
• Pizza boxes (torn into small pieces)

Avoid meat, dairy, and oily foods, as these can attract pests and create odors. In Hillsboro, residents with yard debris service can add food scraps to their yard debris roll carts.

Yard Debris and Other Organics

Yard waste makes up a significant portion of compostable materials. Leaves, grass clippings, and small twigs are all excellent additions. Prunings from trees and shrubs can be composted if chopped into small pieces. Other compostable yard debris includes:

• Pine cones and needles
• Soil from potted plants
• Moss and lichen
• Straw or hay

Avoid adding diseased plants or weeds with seeds. Large branches should be chipped before composting. Hillsboro residents can place yard debris and food scraps in their yard debris roll carts for curbside collection.

Composting Methods

Hillsboro residents have several effective composting options to choose from. Each method offers unique benefits and can be tailored to different living situations and composting goals.

Traditional Composting

Traditional composting involves creating a compost pile outdoors. This method works well for those with yard space. Start by layering “green” materials like food scraps and grass clippings with “brown” materials such as dry leaves and twigs.

Aim for a balance of about 3 parts brown to 1 part green. Turn the pile regularly to aerate it and maintain moisture. This method can handle large volumes of organic waste.

Properly managed piles generate heat, speeding up decomposition. Traditional composting is ideal for producing compost for gardens and landscaping.

Vermicomposting

Vermicomposting uses worms to break down organic matter. It’s perfect for apartment dwellers or those with limited outdoor space. Use a specialized bin with red wiggler worms.

Feed the worms a mix of fruit and vegetable scraps, coffee grounds, and shredded paper. Avoid meat, dairy, and oily foods. The worms produce nutrient-rich castings, excellent for houseplants and container gardens.

This method is odorless when done correctly, making it suitable for indoor use. Vermicomposting works year-round and produces compost faster than traditional methods.

Hot Composting

Hot composting accelerates the decomposition process. It requires careful management of carbon-to-nitrogen ratios, moisture, and aeration. Build a pile at least 3 feet cubed to generate sufficient heat.

Layer green and brown materials, maintaining a 30:1 carbon-to-nitrogen ratio. Monitor the temperature, aiming for 130-150°F. Turn the pile frequently to distribute heat and oxygen.

Hot composting can produce finished compost in as little as 4-6 weeks. It’s effective at killing weed seeds and pathogens due to high temperatures.

Compost Tumblers and Bins

Compost tumblers and bins offer convenient, contained composting options. Tumblers are elevated, rotating containers that make turning compost easy. They’re ideal for small to medium amounts of waste.

Stationary bins come in various sizes and designs. Some have multiple compartments for different composting stages. These systems help control moisture and deter pests.

Both tumblers and bins can be used year-round and are suitable for urban settings. They typically produce compost faster than open piles due to better heat retention and moisture control.

Building and Managing a Compost Pile

Creating a successful compost pile requires careful planning and ongoing maintenance. Proper location, material balance, moisture control, and temperature monitoring are key factors in producing high-quality compost.

Selecting the Right Location

Choose a level, well-drained area for your compost pile. A partially sunny spot is ideal, as it provides warmth without excessive drying. Place the pile away from buildings to prevent pest issues.

Consider using a bin or enclosure to keep the pile neat and contained. Options include commercial bins, DIY wooden structures, or wire mesh enclosures.

Ensure easy access for adding materials and turning the pile. A location near your garden allows for convenient use of finished compost.

Balancing Green and Brown Materials

Maintain a proper ratio of carbon-rich “brown” materials to nitrogen-rich “green” materials. Aim for a 2:1 or 3:1 ratio of browns to greens by volume.

Brown materials include:

• Dry leaves
• Straw
• Shredded paper
• Cardboard

Green materials include:

• Fresh grass clippings
• Fruit and vegetable scraps
• Coffee grounds
• Plant trimmings

Layer browns and greens as you build the pile. This balance promotes efficient decomposition and prevents odors.

Maintaining Moisture and Aeration

Keep the compost pile as moist as a wrung-out sponge. Too much moisture can lead to anaerobic conditions and foul odors. Too little moisture slows decomposition.

Water the pile during dry periods. In rainy weather, cover it to prevent excessive moisture.

Turn the pile regularly to incorporate oxygen. This promotes aerobic decomposition and speeds up the process. Use a pitchfork or compost aerator tool to mix materials thoroughly.

Consider adding bulky materials like small twigs to improve air circulation within the pile.

Monitoring Temperature and Decomposition

A properly functioning compost pile will heat up as microbes break down organic matter. Use a compost thermometer to track internal temperatures.

The pile should reach 130-150°F (54-66°C) during active decomposition. This heat kills weed seeds and pathogens.

If the temperature drops, turn the pile to reactivate the process. Add more greens if needed to boost microbial activity.

Monitor the decomposition progress. Finished compost should be dark, crumbly, and smell earthy. This process typically takes 3-6 months, depending on conditions and management.

Troubleshooting Common Composting Issues

Successful composting requires attentiveness and occasional adjustments. Addressing issues promptly keeps the decomposition process on track and ensures a healthy, productive compost pile.

Dealing with Pests and Odors

Pests and unpleasant odors can disrupt composting efforts. To deter flies, cover fresh kitchen scraps with a layer of dry materials or soil. For persistent fly problems, use a mesh screen to contain the pile.

Ants often indicate a dry compost pile. Add water to moisten the materials and turn the pile to distribute moisture evenly.

Foul odors may signal imbalances in the compost. A rotten egg smell suggests anaerobic conditions from compaction. Turn the pile to improve aeration. An ammonia odor points to excess nitrogen-rich materials. Add carbon-rich materials like dry leaves or shredded paper to restore balance.

Managing Overly Wet or Dry Piles

Proper moisture levels are crucial for effective composting. A soggy pile can become anaerobic and slimy. To fix this:

• Add dry, carbon-rich materials like leaves or straw
• Turn the pile to improve air circulation
• Ensure proper drainage by elevating the pile or adding holes

A dry pile slows decomposition. To address:

• Water the pile, aiming for the moisture level of a wrung-out sponge
• Add fresh green materials high in nitrogen
• Cover the pile to retain moisture

Ensuring Proper Decomposition

Slow decomposition can result from various factors. To speed up the process:

• Chop materials into smaller pieces to increase surface area
• Balance green (nitrogen-rich) and brown (carbon-rich) materials
• Turn the pile regularly to distribute moisture and oxygen
• Maintain proper pile size – at least 3 feet cubed for optimal heat generation

If the pile lacks diversity, add a variety of organic matter. Include both yard waste and kitchen scraps. A mix of materials provides balanced nutrients for decomposing bacteria.

In cold weather, insulate the pile with straw or leaves to maintain heat. Consider using a compost activator to introduce beneficial bacteria and jump-start decomposition.

Using Your Finished Compost

Finished compost offers numerous benefits for gardens and landscaping. This nutrient-rich material improves soil structure, provides essential nutrients, and promotes healthy plant growth.

Incorporating into Garden Soil

Mix finished compost into garden soil to enhance its fertility and structure. Add a 2-4 cm layer of compost over garden beds and work it into the top 15-20 cm of soil. For new plantings, blend compost with existing soil at a 1:3 ratio.

In vegetable gardens, apply compost annually before planting. For perennial beds, top-dress with compost in spring or fall. Compost improves soil’s water retention and drainage while slowly releasing nutrients.

When preparing containers, mix 25-30% compost into potting soil. This provides a nutrient boost and helps retain moisture for potted plants.

Mulch for Landscaping and Plants

Use finished compost as an organic mulch around trees, shrubs, and flowerbeds. Apply a 5-7 cm layer, keeping it away from plant stems and tree trunks. Compost mulch suppresses weeds, conserves soil moisture, and regulates soil temperature.

For landscaping, spread compost over lawn areas to improve soil health. Apply a thin layer (1-2 cm) and rake it in. This technique, known as topdressing, enhances grass growth and reduces the need for chemical fertilizers.

Compost also works well in erosion control. Apply it to slopes and areas prone to soil loss. The organic matter helps bind soil particles and improve water infiltration.

Making and Using Compost Tea

Compost tea is a liquid fertilizer made by steeping finished compost in water. To make it, fill a bucket 1/3 full with compost and add water. Let it steep for 24-48 hours, stirring occasionally.

Strain the mixture and dilute the resulting liquid at a 1:10 ratio with water. Use this nutrient-rich solution to water plants or as a foliar spray. Apply compost tea every 2-4 weeks during the growing season.

For indoor plants, use compost tea monthly to provide a gentle nutrient boost. It’s particularly beneficial for leafy plants and helps promote lush, green growth.
