Basic Composting Principles
Understanding the fundamental principles of composting is crucial for turning your kitchen scraps and yard waste into nutrient-rich compost.
Here's what you need to know:
Balance of Greens and Browns:
Greens: These are nitrogen-rich materials like kitchen scraps (vegetable peels, fruit waste, coffee grounds), fresh grass clippings, and green leaves.
They provide the necessary proteins and amino acids for the microbes that break down the compost.
Browns: These are carbon-rich materials such as dry leaves, straw, wood chips, shredded newspaper, and cardboard.
Browns provide the energy source for microbes and help to balance the moisture in your compost.
Ideal Ratio: A general guideline is to maintain a ratio of about 2-3 parts browns to 1 part greens.
This balance is key to a healthy, odor-free, and efficient composting process.
Size of Materials:
Chopping or Shredding: Smaller pieces decompose faster.
Chopping kitchen waste and shredding yard waste can significantly speed up the composting process.
Surface Area: The more surface area exposed, the easier it is for microbes to do their work.
This principle is especially important in a compost tumbler where space is confined.
Moisture and Aeration:
Moisture Level: The compost should be moist, but not wet.
The consistency should be like a wrung-out sponge.
Too much moisture can lead to a smelly, anaerobic process, while too little can slow down decomposition.
Aeration: Oxygen is crucial for composting.
In a tumbler, this is achieved by turning the bin, which introduces air into the mix.
Regular turning (about once every 2-3 days) is recommended to maintain oxygen levels and distribute moisture evenly.
Temperature:
Heat Generation: As the materials break down, they generate heat, which is a sign of active composting.
The ideal temperature range for effective composting is between 90-140°F (32-60°C).
Monitoring: If you're serious about composting, you might use a compost thermometer to monitor the temperature.
A significant drop in temperature can indicate that it's time to turn the compost or adjust the green-brown ratio.
Here is the composting thermometer I recommend:
Microorganisms:
Natural Process: The decomposition in your compost tumbler is carried out by naturally occurring microorganisms such as bacteria and fungi.
Activators: While not necessary, compost activators can be added to introduce a higher concentration of these microorganisms, potentially speeding up the process.
Here is the compost activator I recommend:
Time and Patience:
Composting Duration: Depending on the balance of materials, moisture, and temperature, composting can take anywhere from a few weeks to a few months.
Observation and Adjustment: Regular observation and adjustment are key.
If your compost is too wet, add more browns; if it's too dry, add greens or a bit of water.
Adding Materials to Your Tumbler
Start adding your kitchen scraps, yard waste, and other compost materials.
Remember not to add meat, dairy, or oily foods to prevent odors and pests.

Maintaining Your Compost Tumbler
Effective maintenance of your compost tumbler is key to ensuring a successful composting process.
Here are some detailed steps and tips to keep your tumbler in top shape:
Regular Turning:
Frequency: Turn your compost tumbler every few days, ideally every 2-3 days.
Consistent turning mixes the compost, distributes moisture and air, and speeds up the decomposition process.
Technique: Give the tumbler several good turns to adequately mix the contents.
If your tumbler has a crank handle, use it; otherwise, rotate it manually.
Monitoring Moisture:
Moisture Level: Your compost should be moist but not soggy.
The ideal moisture level is similar to a wrung-out sponge.
Adjustments: If the compost is too wet, add more brown materials (like shredded newspaper or dry leaves) to absorb excess moisture.
If it's too dry, add water sparingly or include more green materials.
Checking for Odor:
Odor Identification: A healthy compost should have an earthy smell.
If you notice foul odors, it might be a sign of imbalance.
Addressing Odor Issues: Bad smells often indicate too much moisture or an excess of green materials.
Adjust by adding browns and ensuring proper aeration through turning.
Managing Temperature:
Warmth is Good: A warm compost tumbler indicates active decomposition.
It's normal for the tumbler to feel warm to the touch.
Too Hot or Too Cold: If the compost gets excessively hot, it might need more frequent turning or more browns.
If it's too cold, check if it's too dry or needs more greens.
Observing Decomposition:
Progress Check: Regularly observe the changing texture and color of the compost.
It should gradually become darker and finer over time.
Complete Decomposition: Finished compost is dark, crumbly, and has an earthy smell.
It shouldn't have any recognizable food or yard waste pieces.
Harvesting Compost:
Timing: Depending on conditions, compost can be ready in 2-6 months.
When the compost appears dark and rich, it's likely ready to use.
Harvesting Process: Many tumblers have a hatch or door for removing compost.
Use a shovel or bucket to collect the finished compost.
Continuous Composting:
Adding New Materials: If you have a dual-chamber tumbler, you can continuously add new materials to one chamber while the other finishes composting.
Management: Keep track of which chamber is in which stage of composting for a steady supply of compost.
Cleaning and Maintenance:
Regular Cleaning: Clean the tumbler occasionally to prevent buildup and ensure smooth operation.
A hose-down with water is usually sufficient.
Checking for Wear: Periodically inspect your tumbler for any signs of wear and tear, especially the moving parts like hinges or the axle.
