Composting Basics

Composting transforms organic waste into valuable soil amendment. This natural process enriches gardens while reducing landfill waste.

What Is Composting?

Composting is the controlled decomposition of organic matter. It breaks down materials like food scraps and yard waste into nutrient-rich humus. Microorganisms, insects, and worms work together to create this dark, crumbly substance.

The process requires four key elements:

• Carbon-rich “browns” (dry leaves, straw)
• Nitrogen-rich “greens” (grass clippings, food scraps)
• Water
• Oxygen

Proper balance of these ingredients speeds decomposition. A ratio of about 3 parts browns to 1 part greens works well. Regular turning aerates the pile and distributes moisture.

Benefits of Composting

Composting offers numerous advantages for gardeners and the environment. It improves soil structure and water retention. Plants thrive in compost-enriched soil, reducing the need for chemical fertilizers.

Key benefits include:

• Enhances soil fertility
• Suppresses plant diseases and pests
• Reduces landfill waste
• Lowers carbon footprint

Compost also helps sandy soils retain water and loosens clay soils. It provides a slow-release source of nutrients for plants. This natural fertilizer promotes healthy root systems and vigorous plant growth.

Setting Up Your Compost System

Creating an effective composting system in Rialto, CA requires careful planning and setup. The right location, bin selection, and construction methods are key to success.

Choosing the Right Location

Select a spot in your Rialto yard that’s easily accessible and convenient. Aim for a level area with good drainage to prevent waterlogging. Partial shade is ideal, as it helps maintain moisture without overheating the compost.

Consider proximity to your kitchen for easy disposal of food scraps. Keep the bin at least 2 feet away from structures to allow air circulation.

In Rialto’s warm climate, protect your compost from excessive sun exposure to prevent rapid drying.

Selecting a Compost Bin

Rialto residents can choose from various compost bin options. Enclosed bins work well to deter pests and control moisture. Tumbling bins make turning compost easy but have limited capacity.

Stationary bins are best for larger volumes. Look for bins with good ventilation and secure lids. Many hardware stores in Rialto offer compost bins designed for the local climate.

Consider size based on your yard waste and kitchen scrap production. A typical family might need a 3x3x3 foot bin.

DIY Compost Bins

Building your own compost bin can be cost-effective and tailored to your needs. A simple wire mesh bin is easy to construct. Use 3-4 sturdy poles and wrap them with wire mesh, leaving one side open for access.

Wooden pallet bins are another popular DIY option. Stack four pallets vertically to form a square, securing them at the corners. Add a fifth pallet as a removable front panel for easy access.

For a more permanent solution, construct a three-bin system using concrete blocks or wood. This allows for different stages of composting simultaneously.

Materials for Composting

Successful composting relies on balancing green and brown materials while avoiding certain items that can harm the process. Proper selection of ingredients is key to creating nutrient-rich compost for your garden.

Greens and Browns

Greens provide nitrogen and moisture to your compost pile. These include kitchen scraps like vegetable and fruit peels, coffee grounds, and tea bags. Yard waste such as fresh grass clippings and green leaves also fall into this category.

Browns supply carbon and help aerate the pile. Examples include dry leaves, straw, newspaper, cardboard, and wood chips. Aim for a ratio of about 3 parts browns to 1 part greens by volume.

Eggshells can be added to either category. They provide calcium and help balance acidity. Crush them first to speed decomposition.

Mix greens and browns thoroughly when adding to your pile. This ensures proper distribution of nutrients and promotes faster breakdown of materials.

Items to Avoid

Certain materials can attract pests or introduce harmful substances to your compost. Avoid adding meat, bones, dairy products, and oils. These can create odors and draw unwanted animals.

Diseased plants should not be composted, as pathogens may survive the process. Cat and dog waste can contain parasites and should be kept out of compost used for food gardens.

Avoid adding chemically treated wood products, as they may introduce toxins. Glossy or colored paper should also be excluded.

Large branches or thick woody materials decompose slowly. Chop or shred these items before adding to speed up the process.

Composting Methods

Composting transforms organic waste into nutrient-rich soil. Several methods suit different needs and environments. Each technique offers unique advantages for turning kitchen scraps and yard waste into valuable compost.

Hot Composting

Hot composting is a fast, efficient method that generates high temperatures. It requires careful management of carbon-to-nitrogen ratios, moisture levels, and oxygen flow. Gardeners mix green materials (nitrogen-rich) with brown materials (carbon-rich) in a 1:3 ratio.

The pile should be at least 3 feet cubed to retain heat. Regular turning every few days maintains oxygen levels and promotes even decomposition. Temperatures can reach 130-150°F, killing weed seeds and pathogens.

This method can produce usable compost in 4-8 weeks. It’s ideal for those with large amounts of organic waste and the time to manage the process actively.

Cold Composting

Cold composting is a low-maintenance approach suitable for small-scale waste management. It involves layering organic materials and letting them decompose naturally over time.

This method doesn’t require frequent turning or precise ingredient ratios. Gardeners simply add materials as they become available. Decomposition occurs at ambient temperatures, typically taking 6-12 months to produce finished compost.

While slower, cold composting is less labor-intensive and works well for those with limited time or physical ability. It’s also a good option for continuous, small-batch composting throughout the year.

Vermicomposting

Vermicomposting uses worms to break down organic matter. Red wigglers (Eisenia fetida) are the most common species used. This method is ideal for indoor composting or areas with limited outdoor space.

A typical setup includes a bin with bedding material, food scraps, and worms. The worms consume the organic matter and produce nutrient-rich castings. Proper moisture levels and temperature control (55-77°F) are essential for worm health.

Vermicomposting produces high-quality compost in 3-6 months. It’s odorless when managed correctly, making it suitable for apartment dwellers or offices.

Bokashi

Bokashi is an anaerobic fermentation process originating from Japan. It uses beneficial microorganisms to break down organic matter, including meat and dairy, which are typically avoided in traditional composting.

The process involves layering food waste with bokashi bran in an airtight container. The bran contains effective microorganisms that ferment the waste. After 2-4 weeks, the pre-compost is buried in soil to complete decomposition.

Bokashi is fast, odorless, and space-efficient. It’s particularly useful for urban environments or where traditional composting isn’t feasible. The resulting compost is highly acidic and nutrient-rich.

Maintaining Your Compost Pile

Proper maintenance is crucial for a healthy, productive compost pile. Regular attention to key factors ensures optimal decomposition and nutrient-rich results.

Balancing Greens and Browns

A well-balanced compost pile requires a mix of nitrogen-rich “green” materials and carbon-rich “brown” materials. Greens include grass clippings, food scraps, and fresh plant matter. Browns consist of dry leaves, straw, and wood chips. Aim for a ratio of about 3 parts browns to 1 part greens by volume.

Add materials in layers, alternating between greens and browns. This promotes even distribution and prevents clumping. If the pile smells rotten, add more browns. If decomposition slows, add more greens.

Consider using a compost bin or enclosure to contain materials and maintain neat aesthetics.

Aeration and Turning

Oxygen is essential for aerobic decomposition. Turn the pile every 1-2 weeks using a pitchfork or compost aerator. This process introduces fresh air, redistributes materials, and accelerates breakdown.

Pay attention to the pile’s center, where decomposition is most active. Move outer materials inward during turning to ensure even decomposition. For larger piles, create air channels by inserting perforated pipes vertically.

If manual turning is challenging, consider using a tumbling composter for easier maintenance.

Moisture and Temperature Control

Maintain proper moisture levels in your compost pile. It should feel like a wrung-out sponge – damp but not soggy. If too dry, add water while turning. If too wet, add dry browns and turn to improve drainage.

Monitor compost temperature using a compost thermometer. Ideal temperatures range from 130-150°F (54-66°C). Higher temperatures indicate active decomposition and help kill weed seeds and pathogens.

In hot, dry climates like Rialto, CA, cover the pile to retain moisture. During cooler months, insulate with straw or leaves to maintain heat.

Using Your Finished Compost

Finished compost offers numerous benefits for garden soil and plant health. It can be applied directly to garden beds, used to make nutrient-rich compost tea, or mixed with potting soil for containers.

Identifying Finished Compost

Properly finished compost has a dark, crumbly texture similar to rich soil. It should have an earthy smell and no traces of the original materials used. The composting process typically takes 3-6 months when managed actively.

To test if compost is ready, place a handful in a sealed plastic bag for 24 hours. If it develops a sour odor upon opening, it needs more time to decompose. Finished compost should maintain its pleasant earthy scent.

Applications in the Garden

Spread a 2-4 cm layer of finished compost over garden beds and gently mix it into the top few inches of soil. This improves soil structure and provides slow-release nutrients.

For new plantings, blend compost into the soil at a ratio of about 1 part compost to 3 parts existing soil. When transplanting, add a handful of compost to each planting hole.

Top-dress established plants by applying a thin layer around the base, taking care not to pile it against stems. Use compost as a mulch to retain soil moisture and suppress weeds.

Compost Tea

Compost tea concentrates the nutrients and beneficial microorganisms found in finished compost. To make it, steep compost in water for 24-48 hours, stirring occasionally.

Use a ratio of 1 part compost to 5-10 parts water. Strain the liquid and dilute it further if needed. Apply compost tea as a foliar spray or soil drench to boost plant health.

For indoor plants, mix compost tea with regular watering once a month. Outdoor plants can receive compost tea applications every 2-4 weeks during the growing season.
