Composting: Why All the Fuss?
Composting is nature's way of recycling. It's the process of decomposing organic matter – like food scraps and yard waste – into a nutrient-rich soil amendment commonly called 'black gold'. This 'black gold' is a fantastic addition to your garden, offering a multitude of benefits for your plants and the environment. But what exactly makes composting so valuable?
Benefits of Composting for Your Garden
- Enriched Soil: Compost adds essential nutrients back into the soil, improving its structure, water retention, and aeration. This creates an ideal environment for healthy plant growth.
- Reduced Need for Chemical Fertilizers: By using compost, you can significantly reduce or even eliminate the need for synthetic fertilizers, which can be harmful to the environment.
- Water Conservation: Compost's improved water retention means you'll need to water your plants less frequently.
- Waste Reduction: Composting reduces the amount of waste sent to landfills, which helps conserve valuable resources and reduces methane emissions. According to the EPA, food scraps and yard waste together make up 24% of municipal solid waste in landfills (EPA Website).
- Disease Suppression: Some studies suggest that compost can help suppress certain plant diseases and pests.
Composting Methods: Choosing the Right System for You
There are several different composting methods, each with its own advantages and disadvantages. The best method for you will depend on your available space, time commitment, and desired outcome.
1. Traditional Composting (Hot Composting)
Traditional composting involves creating a compost pile or bin outdoors and layering 'green' (nitrogen-rich) materials with 'brown' (carbon-rich) materials. The key to hot composting is maintaining the right balance of ingredients, moisture, and aeration to encourage rapid decomposition.
What to Compost: The Green and Brown Rule
- Greens (Nitrogen-Rich): These materials provide nitrogen, which is essential for the growth of microorganisms that break down organic matter. Examples include: grass clippings, fruit and vegetable scraps, coffee grounds, tea bags, and fresh manure.
- Browns (Carbon-Rich): These materials provide carbon, which serves as an energy source for the microorganisms. Examples include: dried leaves, straw, shredded paper, cardboard, wood chips, and sawdust.
A good rule of thumb is to aim for a 2:1 or 3:1 ratio of browns to greens. This provides the ideal balance for efficient decomposition.
Building Your Traditional Compost Pile
- Choose a Location: Select a well-drained location in your yard that receives partial shade.
- Start with a Layer of Browns: Begin with a layer of coarse brown materials, such as twigs or branches, to improve drainage.
- Layer Greens and Browns: Alternate layers of green and brown materials, ensuring that each layer is no more than a few inches thick.
- Moisten the Pile: Keep the compost pile moist, but not soggy, like a wrung-out sponge. Add water as needed, especially during dry periods.
- Turn the Pile Regularly: Turn the compost pile every few days with a pitchfork or compost turner to aerate it and speed up decomposition. This helps maintain the optimal temperature of 130-160°F for killing weed seeds and pathogens.
Troubleshooting Traditional Composting
- Smelly Compost: A foul odor usually indicates that the compost pile is too wet or lacks aeration. Turn the pile regularly and add more brown materials to absorb excess moisture.
- Slow Decomposition: Slow decomposition can be caused by several factors, including a lack of nitrogen, insufficient moisture, or inadequate aeration. Add more green materials, moisten the pile, and turn it more frequently.
2. Tumbler Composting
Tumbler composters are enclosed containers that rotate, making it easier to aerate the compost pile. They are a convenient option for those who want to compost more quickly and with less manual labor.
Benefits of Tumbler Composting
- Faster Decomposition: Tumbling the compost pile regularly ensures adequate aeration, which speeds up decomposition.
- Less Manual Labor: Tumblers eliminate the need for manual turning with a pitchfork.
- Pest Control: Enclosed tumblers can help keep pests, such as rodents and insects, out of the compost pile.
- Aesthetically Pleasing: Tumblers are more visually appealing than traditional compost piles.
Using a Tumbler Composter
- Choose a Tumbler: Select a tumbler that is the right size for your needs and has good ventilation.
- Add Greens and Browns: Add green and brown materials to the tumbler, maintaining a 2:1 or 3:1 ratio.
- Tumble Regularly: Rotate the tumbler every few days to aerate the compost pile.
- Monitor Moisture: Keep the compost pile moist, but not soggy. Add water as needed.
3. Vermicomposting (Worm Composting)
Vermicomposting uses worms, specifically red wigglers (Eisenia fetida), to break down organic matter. Worms consume food scraps and excrete worm castings, which are a highly valuable soil amendment.
Benefits of Vermicomposting
- Nutrient-Rich Compost: Worm castings are incredibly rich in nutrients and beneficial microbes.
- Odorless: When properly maintained, vermicomposting is virtually odorless.
- Indoor Composting: Vermicomposting can be done indoors, making it a great option for apartment dwellers.
Setting Up a Vermicomposting Bin
- Choose a Bin: Select a plastic bin with a lid and drainage holes.
- Add Bedding: Create a bedding material using shredded newspaper, cardboard, or coconut coir.
- Add Worms: Purchase red wiggler worms from a reputable source.
- Add Food Scraps: Bury food scraps in the bedding, avoiding meat, dairy, and oily foods.
- Maintain Moisture: Keep the bedding moist, but not soggy.
Feeding Your Worms
Worms can eat a wide variety of food scraps, including:
- Fruit and vegetable scraps
- Coffee grounds and tea bags
- Bread and grains
- Crushed eggshells
Avoid feeding worms meat, dairy, oily foods, or citrus peels in large quantities.
4. Bokashi Composting
Bokashi composting is an anaerobic (oxygen-free) fermentation process that uses a special bran inoculated with beneficial microorganisms to break down food waste. It's particularly effective for composting meat, dairy, and oily foods, which are typically avoided in other composting methods.
Benefits of Bokashi Composting
- Composts All Food Waste: Bokashi composting can handle all types of food waste, including meat, dairy, and oily foods.
- Anaerobic Process: No turning is required.
- Reduced Odor: The fermentation process minimizes odors.
Using a Bokashi Composting Bucket
- Collect Food Waste: Place food waste in the Bokashi bucket.
- Add Bokashi Bran: Sprinkle Bokashi bran over each layer of food waste.
- Press Down: Press down on the food waste to remove air pockets.
- Drain Liquid: Drain the liquid (leachate) from the bucket every few days. The leachate can be diluted and used as a fertilizer.
- Ferment: Once the bucket is full, seal it tightly and allow it to ferment for two weeks.
- Bury or Add to Compost Pile: After fermentation, bury the fermented material in the garden or add it to a traditional compost pile.
What NOT to Compost
While composting is a great way to recycle organic matter, there are some materials that should be avoided, as they can attract pests, spread diseases, or contaminate the compost.
- Meat and Dairy: These materials can attract pests and create unpleasant odors.
- Oily Foods: Oily foods can slow down decomposition and create a greasy compost.
- Diseased Plants: Diseased plants can spread pathogens to other plants through the compost.
- Weed Seeds: Weed seeds can survive the composting process and germinate in the garden. Hot composting is necessary to kill weed seeds.
- Pet Waste: Pet waste can contain harmful bacteria and parasites.
- Black Walnut Tree Debris: Juglone, a chemical produced by black walnut trees, is toxic to many plants.
Putting Compost to Use in Your Garden
Once your compost is ready, you can use it in a variety of ways to improve your garden soil and plant health.
1. Soil Amendment
Mix compost into your garden soil before planting to improve its structure, water retention, and fertility. A good rule of thumb is to amend the soil with 2-4 inches of compost.
2. Topdressing
Apply a layer of compost around the base of existing plants to provide them with essential nutrients. This is especially beneficial for heavy feeders like tomatoes and peppers.
3. Potting Mix
Mix compost with other ingredients like peat moss or coconut coir to create a nutrient-rich potting mix for container plants. Limit the amount of compost to 1/3 of the total volume.
4. Compost Tea
Compost tea is a liquid fertilizer made by steeping compost in water. It is a great way to provide plants with a quick boost of nutrients and beneficial microbes.
