Why Bother? The Amazing Benefits of Things to Compost
Before we dive into the nitty-gritty lists, let’s talk about the “why.” Trust me, once you see the magic it works, you’ll be hooked. Composting isn’t just about reducing landfill waste (though that’s a fantastic bonus!); it’s one of the single best things you can do for your garden’s health.
Here are just a few of the incredible benefits of things to compost:
- Enriches Your Soil: Compost is packed with essential nutrients and beneficial microorganisms. Adding it to your garden beds is like giving your plants a supercharged multivitamin, helping them grow stronger and more resilient.
- Improves Soil Structure: Have heavy clay soil? Compost lightens it up, improving drainage. Have sandy soil that water runs right through? Compost helps it retain moisture. It’s a miracle worker for any soil type!
- Reduces Your Carbon Footprint: When organic matter rots in a landfill, it releases methane, a potent greenhouse gas. Composting at home is a powerful, eco-friendly things to compost practice that significantly cuts down on this waste.
- Saves You Money: Why buy bags of fertilizer and soil conditioners when you can create your own superior version for free? You’ll reduce your need for chemical fertilizers, which is better for your wallet and the planet.
The Heart of Your Compost: Understanding Greens and Browns
Okay, friend, here’s the most important secret to successful composting. It’s all about balance. Think of it like making a cake—you need the right ingredients in the right proportions. In composting, our ingredients are simply “Greens” and “Browns.”
This is the foundation of any good things to compost guide. Getting this balance right prevents most common problems before they even start.
“Greens” – The Nitrogen-Rich Activators
“Greens” are the fresh, moist materials that are rich in nitrogen. They are the fuel for your compost pile, providing the protein that the hardworking microorganisms need to multiply and break everything down. They are the “heat” generators.
Common Green Materials Include:
- Fruit and vegetable scraps
- Coffee grounds and used tea bags
- Fresh grass clippings
- Plant trimmings and annual weeds (that haven’t gone to seed!)
- Eggshells (crushed for faster breakdown)
- Livestock manure (from herbivores like chickens, rabbits, or cows—never from cats or dogs)
“Browns” – The Carbon-Rich Bulk
“Browns” are the dry, woody materials that are rich in carbon. They provide the structure and bulk for your compost pile, creating air pockets that are essential for the aerobic bacteria to breathe. They prevent the pile from becoming a slimy, smelly mess.
Common Brown Materials Include:
- Dried leaves and straw
- Wood chips, sawdust, and small twigs
- Shredded newspaper and cardboard (non-glossy)
- Paper towel and toilet paper rolls
- Dried-out corn stalks
- Pine needles (in moderation)
The Golden Ratio: Getting the Balance Right
Here’s the simple rule of thumb: Aim for roughly two to three parts Browns to one part Greens by volume. Don’t worry about being perfectly precise! This isn’t a science experiment.
If you add a bucket of kitchen scraps (Greens), try to add two or three buckets of shredded leaves or cardboard (Browns). This ratio provides the ideal environment for decomposition without bad odors. It’s one of the most crucial things to compost tips I can share.
The Ultimate “Yes” List: Fantastic Things to Compost
Now for the fun part! Here is a comprehensive list of all the wonderful materials you can add to your pile. This is your go-to reference for how to turn everyday waste into garden gold. Embracing these sustainable things to compost will make a huge difference.
From the Kitchen
Your kitchen is a treasure trove of compostable materials. Keep a small pail with a lid on your counter to collect these goodies.
- All Fruit & Vegetable Scraps: Peels, cores, stems, rinds, and old produce. Chop up larger items like watermelon rinds to speed up decomposition.
- Eggshells: An excellent source of calcium. Rinse them and crush them into small pieces.
- Coffee Grounds & Paper Filters: Coffee grounds are nitrogen-rich (a “Green”) and worms love them.
- Tea Bags & Loose-Leaf Tea: Just be sure to remove any plastic-based mesh bags or staples first.
- Stale Bread, Pasta & Grains: Add these in moderation and be sure to bury them in the center of the pile to avoid attracting pests.
- Corn Cobs & Husks: Cobs take a while to break down, so consider breaking them in half.
- Nut Shells: (Except for walnut shells, which can inhibit plant growth). Crush them first.
From the Garden & Yard
Your yard provides the “Browns” that are essential for balancing your pile.
- Leaves: The absolute best “Brown” material. Shred them with a mower first if you can for lightning-fast results.
- Grass Clippings: A fantastic “Green,” but add them in thin layers and mix well with Browns to prevent them from becoming a slimy, matted mess.
- Yard Trimmings: Deadheaded flowers, pruned stems, and green leaves are all great additions.
- Weeds: Yes, you can! But only if they haven’t developed seed heads. You don’t want to be planting weed seeds back into your garden.
- Wood Ash: Use sparingly from untreated wood fires. It adds potassium but can raise the pH.
- Small Twigs & Wood Chips: These add excellent structure and air pockets, though they take longer to break down.
Surprising (But Safe!) Household Items
Think beyond the kitchen and garden! Many everyday items can join the compost party.
- Shredded Paper & Cardboard: Newspaper, non-glossy mail, and cardboard boxes (with tape removed) are excellent “Browns.”
- Cardboard Tubes: From paper towels and toilet paper. Rip them up first.
- Dryer Lint & Vacuum Cleaner Dust: As long as you’re cleaning up natural fibers (cotton, wool, pet hair, dirt).
- Pet Fur & Human Hair: Full of nitrogen!
- Cotton & Wool Fabric: Cut up old 100% cotton or wool clothing into small scraps.
- Used Paper Napkins & Paper Towels: As long as they weren’t used with harsh chemical cleaners.
The “Hold On!” List: Things to Avoid in Your Compost Pile
Knowing what not to compost is just as important as knowing what to add. Adding the wrong items is the source of most common problems with things to compost, leading to foul odors, pests, and a pile that just won’t break down.
The Absolute “No-Gos”
These items should never go into a typical home compost pile. They attract rodents and other pests, create horrible smells, and can harbor harmful pathogens.
- Meat, Fish, and Bones: The number one rule. They rot, smell terrible, and are a magnet for pests.
- Dairy Products: Milk, cheese, yogurt, etc. Same reasons as meat.
- Oils, Fats, and Grease: These coat other materials, creating an anaerobic (oxygen-free) environment that smells rancid.
- Pet Waste (from cats or dogs): Can contain parasites and pathogens harmful to humans.
- Treated or Painted Wood: The chemicals can leach into your finished compost and harm your plants.
- Coal or Charcoal Ash: Contains sulfur and other chemicals that are bad for soil.
Items to Use with Caution
These aren’t a hard “no,” but you need to be mindful when adding them.
- Diseased or Insect-Infested Plants: A hot compost pile (one that reaches 140-160°F) can kill most pathogens and pests. If you’re not sure your pile gets hot enough, it’s safer to discard these plants.
- Pernicious Weeds: Weeds like bindweed or quackgrass can regrow from small root fragments. Avoid adding their roots unless you are a very confident hot composter.
- Citrus Peels & Onions: These can be very acidic and some compost worms dislike them. Use them in moderation and they’ll be fine.
- Glossy or Coated Paper: The coatings often contain plastics or clays that don’t break down.
How to Things to Compost: Best Practices for Success
You’ve got your lists of “yes” and “no.” Now, let’s put it all together! Following this simple things to compost care guide will ensure your pile is happy, healthy, and productive.
Choosing Your Composter
You don’t need anything fancy. You can start with a simple open pile in a corner of your yard. Or, you can use a contained system like a wooden bin, a plastic compost bin, or a tumbler, which makes turning easier.
Building Your Pile, Layer by Layer
- Start with a Base: Begin with a 4-6 inch layer of coarse “Browns” like small twigs or wood chips at the bottom. This helps with aeration and drainage.
- Add a Layer of Greens: Add a 2-3 inch layer of your “Greens” (kitchen scraps, grass clippings).
- Add a Layer of Browns: Top the Greens with a 4-6 inch layer of “Browns” (shredded leaves, cardboard). This is your “odor-eater” layer.
- Add a Sprinkle of Soil: A shovel-full of garden soil or finished compost can help introduce beneficial microorganisms to kickstart the process.
- Moisten Lightly: Sprinkle with a little water. Your pile should be as damp as a wrung-out sponge, not soggy.
- Repeat: Continue layering Greens and Browns until your pile is at least 3 feet by 3 feet by 3 feet, which is the ideal size to generate heat.
Maintaining Your Compost
Your compost pile is a living thing! It just needs a little attention. Turn the pile with a pitchfork every week or two to mix everything together and introduce oxygen. Check the moisture level when you turn it; add water if it’s dry or more Browns if it’s too wet.
Solving Common Problems with Things to Compost
Don’t worry if you run into a little trouble—it happens to every gardener! Here’s how to troubleshoot the most common issues.
“My Compost Smells Awful!”
A foul, ammonia-like smell usually means your pile has too many “Greens” or is too wet. It’s gone anaerobic. The fix: Fluff it up with a pitchfork to get air in and add a generous layer of “Browns” like shredded leaves or cardboard. Mix it in well.
“My Compost Isn’t Heating Up.”
A cold pile is a slow pile. This usually means it’s either too dry, too small, or doesn’t have enough “Greens.” The fix: Check the moisture and add water if needed. If it’s moist enough, add a fresh layer of “Greens” like grass clippings or kitchen scraps and mix it into the center.
“I Have Pests in My Pile!”
A few bugs are normal, but if you’re seeing rodents, it’s a sign you’ve added the wrong things (like meat or dairy). The fix: Stop adding prohibited items immediately. Always bury your fresh kitchen scraps in the center of the pile, and make sure you have a good cap of “Browns” on top.
Frequently Asked Questions About Things to Compost
How long does it take to make compost?
It depends on your method! A “hot,” well-managed pile can produce finished compost in as little as 4-6 weeks. A more passive, “cold” pile might take six months to a year. Either way, you’ll get there!
Can I compost paper with ink on it, like newspaper?
Yes! Most modern inks, especially for newspapers, are soy-based and perfectly safe to compost. Avoid glossy, colored magazine pages as they can contain heavy metals or plastics.
Are coffee grounds and filters okay to compost?
Absolutely! Coffee grounds are a fantastic source of nitrogen (a “Green”), and paper filters are a “Brown.” You can toss the whole thing in. Worms especially love coffee grounds.
What about composting weeds?
It’s best to compost weeds before they go to seed. If they have seed heads, only add them to a pile you know gets very hot, otherwise you risk spreading weed seeds all over your garden when you use the compost.
Your Garden’s Future is in Your Hands
See? You’ve got this! Composting isn’t a complicated science; it’s a simple, rewarding process of partnership with nature. You’re taking what would be waste and transforming it into life-giving food for your soil.
Start small. Don’t feel pressured to be perfect. Just begin collecting those kitchen scraps and fall leaves, and you’ll be on your way to creating the most incredible, nutrient-rich amendment for your garden.
So grab a bucket and start today. Your thriving, happy plants will thank you for it!
