Why Compost Yard Waste? The Big Wins
Composting isn’t just about getting rid of stuff. It’s about creating value. When you compost yard waste, you’re doing several great things:
- Enriches Your Soil: Compost adds vital nutrients and organic matter to your soil. This means healthier, happier plants that are more resistant to pests and diseases.
- Reduces Landfill Waste: Yard waste makes up a significant portion of household trash. Composting diverts this material, reducing the burden on landfills.
- Saves Money: You’ll buy less fertilizer and soil amendments. Plus, reducing trash can sometimes lower disposal costs.
- Improves Soil Structure: Compost helps sandy soils retain moisture and improves drainage in clay soils. It’s a win-win for all soil types!
- Environmentally Friendly: Composting reduces the need for chemical fertilizers and pesticides, which can harm ecosystems. It also captures carbon in the soil.
What Yard Waste CAN You Compost?
Most of what you find in your yard is compostable. Think of it as “greens” and “browns.”
“Greens” (Nitrogen-Rich Materials):
These are generally moist and break down quickly, providing nitrogen for the composting microbes.
- Grass clippings (fresh)
- Vegetable and fruit scraps (from the kitchen)
- Coffee grounds and tea bags
- Plant trimmings (from healthy plants)
- Weeds (before they go to seed!)
“Browns” (Carbon-Rich Materials):
These are drier and provide carbon, helping to balance the nitrogen and create air pockets for good decomposition.
- Dry leaves
- Twigs and small branches (chopped up)
- Straw and hay
- Shredded newspaper and cardboard (non-glossy)
- Sawdust (from untreated wood)
- Pine needles and cones
What Yard Waste Should You AVOID Composting?
While most yard waste is a composting superstar, some items are best left out to avoid problems:
- Diseased plants: You don’t want to spread plant diseases to your garden.
- Weeds gone to seed: These can germinate in your compost and spread to your garden beds.
- Pet waste (dog and cat): Can contain harmful pathogens that don’t always break down completely.
- Invasive weeds: Some persistent weeds can survive composting temperatures and spread.
- Treated wood (sawdust or chips): Chemicals can leach into your compost.
- _Oils, greases, and meat/dairy scraps:_ These can attract pests and create foul odors. (Though these aren’t typically yard waste, they’re good to know for general composting.)
Getting Started: Choosing Your Composting Method
There are a few popular ways to compost yard waste, and the best one for you depends on your space, how much yard waste you have, and how quickly you want compost. Let’s break them down:
1. The Simple Pile (Heap Composting)
This is the no-fuss, no-bin-needed approach. You just start piling your yard waste in a designated spot.
Pros:
- Easiest and cheapest to start.
- Can handle large volumes of material.
- Minimal effort.
Cons:
- Can look messy if not managed.
- Takes longer to break down.
- Harder to control temperature and moisture.
Best for: Those with plenty of space, a lot of yard waste, and who aren’t in a hurry for finished compost.
2. The Compost Bin
Compost bins are enclosed containers that help keep things tidy and can speed up the composting process. They come in many forms:
- Stationary Bins: These are often made of wood, wire mesh, or recycled plastic. You add materials to the top and usually harvest finished compost from a door at the bottom.
- Tumbler Bins: These are rotating drums that make turning your compost very easy, speeding up decomposition significantly. They also keep pests out effectively.
- DIY Bins: You can build your own from pallets, chicken wire, or old lumber.
Pros:
- Neater appearance.
- Can retain heat and moisture better, speeding up decomposition.
- Can deter pests.
- Tumblers are easy to turn.
Cons:
- Can be more expensive (unless DIY).
- May have a limited capacity.
- Turning stationary bins can be a bit more work.
Best for: Homeowners with a moderate amount of yard waste, those who want a tidier look, or faster compost production.
3. Trench Composting
This method involves digging a trench or hole in your garden and burying your yard waste directly. Over time, it decomposes in place, enriching the soil.
Pros:
- Extremely simple – no turning required.
- Keeps things out of sight.
- Directly benefits the soil where you bury it.
Cons:
- You can’t easily access finished compost for use elsewhere.
- Can take longer than other methods.
- Requires digging.
Best for: Gardeners who want to improve specific garden beds over time and don’t mind a slower process.
How to Build Your Compost Pile: The Easy Steps
Ready to get your hands dirty? Here’s how to build a compost pile that works:
Step 1: Choose Your Location
Find a convenient spot that’s:
- Accessible: Easy to get to with your yard waste and tools.
- Well-drained: You don’t want your compost sitting in a puddle.
- Partially Shaded: Full sun can dry it out too quickly, while deep shade might keep it too wet.
- Away from wooden structures: To prevent moisture damage.
Step 2: Gather Your Materials
Start collecting your “greens” and “browns” from the lists above. It’s helpful to have a mix ready before you start building your pile.
Step 3: Build Your Base Layer
Start with a layer of coarse “browns” like twigs and small branches. This helps with air circulation from the bottom. Aim for about 4-6 inches thick.
Step 4: Layer Your Greens and Browns
Alternate layers of greens and browns. A good starting ratio is about two to three parts browns to one part greens. For example, three shovelfuls of leaves for one shovelful of grass clippings.
Why the layers? This balance is key! Too many greens can make your pile wet and smelly. Too many browns will make it decompose very slowly.
Step 5: Chop or Shred Larger Items
The smaller the pieces, the faster they break down. Chop up large leaves, small branches, and cardboard before adding them. A lawnmower can often shred leaves nicely.
Step 6: Add Water
Your compost pile should be about as damp as a wrung-out sponge. If it’s too dry, the decomposition slows down. If it’s too wet, it can become anaerobic (lacking air) and smelly. Water each layer lightly as you build your pile.
The Magic Ingredient: Turning Your Compost
This is often the most talked-about part of composting, and it’s crucial for faster, more efficient decomposition. Turning (or “aerating”) your compost introduces oxygen, which the microbes need to do their work.
How Often?
Aim to turn your pile at least once every 1-2 weeks. If you’re using a tumbler, a few spins every few days will do the trick.
How to Turn
Use a garden fork or a compost aerator tool. Dig into the pile and turn it over, mixing the outer materials into the center and the center materials to the outside. This also helps break up any clumps.
What If You Can’t Turn?
If turning sounds like too much work, don’t despair! Your compost will still break down, it will just take longer. This is where larger particle sizes and coarser materials for aeration at the base become even more important. Building the pile with a good mix from the start is your best bet.
How Do You Know When Compost is Ready?
The wait can be the hardest part, but knowing when your compost is ready is rewarding! It typically takes anywhere from two months to a year, depending on your method, the materials you used, and how often you turn it.
Your compost is ready when it:
- Looks dark brown and crumbly, like rich soil.
- Smells earthy and pleasant, not sour or like ammonia.
- The original materials are no longer recognizable.
- It has cooled down. A hot pile means it’s still actively decomposing.
Troubleshooting Common Composting Problems
Even with the best intentions, you might run into a few bumps in the composting road. Here’s how to fix them:
Problem: My compost smells bad (like ammonia or rotten eggs).
Cause: Too much nitrogen (“greens”) or not enough air.
Solution: Add more “brown” materials (leaves, straw, shredded paper) to absorb excess moisture and nitrogen. Turn the pile thoroughly to introduce air. If it’s very wet, try to break up soggy clumps.
Problem: My compost isn’t heating up or breaking down.
Cause: Too many “browns,” not enough “greens,” or it’s too dry.
Solution: Add more nitrogen-rich materials like fresh grass clippings, kitchen scraps, or coffee grounds. Check the moisture level and add water if it’s too dry. Ensure the pile is large enough (at least 3’x3’x3′ is ideal for retaining heat).
Problem: My compost is attracting pests (rodents, flies).
Cause: Including forbidden items like meat, dairy, or oily foods, or the pile is too wet.
Solution: Remove any offending materials immediately. Ensure you’re only composting acceptable yard and kitchen waste. Bury kitchen scraps deep within the pile and cover them with “browns.” A sealed tumbler bin or a wire mesh bin can help deter larger pests.
Tools That Make Composting Easier
While you can compost with just your hands and a shovel, a few simple tools can make the process more efficient and enjoyable:
- Garden Fork: Essential for turning the compost pile.
- Compost Aerator Tool: Specifically designed to easily aerate compost piles without heavy turning.
- Shovel: For moving materials and a great workout!
- Wheelbarrow: To transport yard waste to your compost bin or pile.
- Gloves: To keep your hands clean and protected.
- Water Hose or Watering Can: To maintain the right moisture level.
- Shredder or Chipper (Optional): For those with a lot of branches or large leaves, this significantly speeds up decomposition.
The Science Behind the Magic: What’s Happening?
Composting is a biological process driven by a mix of microorganisms (bacteria, fungi) and larger critters (worms, insects). These organisms feed on the organic matter in your pile. As they eat and reproduce, they break down the materials and generate heat. This heat is crucial for killing weed seeds and pathogens.
The process requires:
- Organic Matter: Your “greens” and “browns.”
- Oxygen: Provided by turning or coarse materials.
- Moisture: Kept at “damp sponge” consistency.
- Right Temperature: Achieved by a good mix and volume.
When these conditions are met, decomposition happens efficiently. For more detailed information on the microbiology of composting, organizations like the MIT OpenCourseware offer deep dives into the scientific principles.
Composting Different Types of Yard Waste
Let’s look at some common yard waste items and how to best compost them:
Grass Clippings
Fresh grass clippings are pure “greens.” They decompose rapidly but can also mat down and create a slimy, anaerobic layer, leading to odors. To avoid this:
- Compost in thin layers (no more than a few inches).
- Mix them thoroughly with “browns,” especially dry leaves or straw.
- If you have a lot, let them dry out for a day or two before adding them.
- Alternatively, use them as mulching in your garden beds (thinly!).
Leaves
Leaves are your composting gold mine – perfect “browns”! They provide carbon and aeration. You can compost them fresh or after they’ve dried.
- Shredding leaves (using a mower) makes them break down much faster.
- Stockpile leaves in the fall; they are a fantastic, free resource.
- Mix them with grass clippings and other “greens” to create a balanced pile.
Twigs and Branches
Small twigs and branches add essential carbon and help create air pockets in your compost pile, preventing compaction. Larger branches take a very long time to break down on their own.
- Chop or shred them into smaller pieces (ideally less than 2 inches).
- Use them as a base layer for good drainage and aeration.
- Branches that are too large for your chipper can be stacked in a corner of your yard to decompose naturally over several years or used as garden stakes.
Pruning Waste
Healthy pruning waste (from ornamental shrubs, trees, etc.) is excellent compost material. Avoid composting material from diseased plants.
- Prune material into smaller pieces for faster decomposition.
- This includes stems, small branches, and spent flowers.
