Introduction
Tired of tossing food scraps in the trash and feeling guilty about the waste? Learning how to make compost from kitchen scraps is one of the simplest, most rewarding ways to reduce waste and feed your garden at the same time. This step-by-step guide shows you how to turn everyday kitchen leftovers into nutrient-rich compost that your plants will love.
Why Composting Kitchen Scraps Matters in the Garden
Food waste makes up a huge portion of household trash — and when it ends up in a landfill, it releases harmful methane gas. Composting transforms kitchen scraps into a natural fertilizer that builds healthy soil, retains moisture, and adds essential nutrients. Instead of buying expensive store-bought fertilizers, you can recycle food scraps into “black gold” that keeps your garden healthy and sustainable. Plus, you’ll help reduce greenhouse gases and create a more eco-friendly home.
Step-by-Step Guide to Making Compost from Kitchen Scraps
Follow these easy steps to turn your food waste into a thriving compost pile.
1. Choose Your Compost Method
First, decide how you want to compost:
- Backyard compost pile or bin: Perfect if you have outdoor space.
- Tumbler bin: Speeds up the process and keeps pests away.
- Indoor compost bin: Small, odor-controlled bins are great for apartments.
- Worm composting (vermicomposting): Uses worms to break down food scraps indoors or outdoors.
Pick the method that fits your space and lifestyle.
2. Gather Composting Materials
Successful composting needs the right balance of “greens” (nitrogen-rich) and “browns” (carbon-rich).
Greens (kitchen scraps):
- Fruit and vegetable peels
- Coffee grounds and filters
- Tea bags (check for plastic!)
- Crushed eggshells
Browns (yard or household waste):
- Dry leaves
- Shredded newspaper or cardboard
- Sawdust (untreated wood only)
- Straw or hay
Avoid adding meat, dairy, oily foods, or pet waste — these attract pests and can create bad odors.
3. Set Up Your Compost Bin
- Place your bin or pile in a dry, shady spot with good drainage.
- Direct contact with soil helps worms and microbes get in and do their job.
- If you’re indoors, use a sealed bin with a charcoal filter or a worm bin to keep odors away.
4. Add Kitchen Scraps Properly
- Chop large scraps into smaller pieces; they’ll break down faster.
- Layer kitchen scraps with browns to prevent your pile from getting too wet or smelly.
- Cover fresh scraps with dry leaves or shredded paper each time you add them.
5. Maintain the Right Balance
The magic ratio is about 2–3 parts browns to 1 part greens. Too many greens? The pile can get soggy and smelly. Too many browns? It may break down too slowly.
Tip: If your pile stinks like rotten eggs, add more browns and turn it to aerate.
6. Keep It Moist, Not Soaked
Your compost should feel like a damp sponge — moist but not dripping. Water it lightly during dry spells. If it’s too wet, add extra browns to soak up excess moisture.
7. Turn the Pile Regularly
- Use a pitchfork or compost aerator to turn your pile every 1–2 weeks.
- Turning adds oxygen, which speeds up decomposition and prevents foul odors.
A compost tumbler makes this easy — just rotate it a few times a week.
8. Watch It Break Down
Depending on your method, compost can be ready in 2–6 months. You’ll know it’s done when:
- It looks dark, crumbly, and soil-like.
- It smells earthy, not rotten.
- You can’t recognize the original scraps anymore.
Sift out any large bits and toss them back into the pile for another round.
Common Mistakes to Avoid
✅ Mistake: Adding meat, dairy, or greasy foods.
Solution: Stick to plant-based scraps, coffee grounds, and eggshells. No meat, bones, or cheese.
✅ Mistake: Letting the pile dry out.
Solution: Check moisture regularly, especially in hot weather, and add water as needed.
✅ Mistake: Not enough airflow.
Solution: Turn your pile often, or poke air holes if using a stationary bin.
✅ Mistake: Pile smells bad.
Solution: Add more browns and turn it. Cover fresh scraps with dry material each time.
✅ Mistake: Only adding kitchen scraps, no browns.
Solution: Always balance with dry leaves, shredded paper, or cardboard.
Extra Tips & Garden Hacks
🌱 Keep a Kitchen Compost Pail: Store scraps in a sealed pail on your counter or under the sink. Empty it into your outdoor bin regularly.
🌱 Freeze Scraps: Freeze scraps to prevent smells if you don’t have time to compost them right away.
🌱 Crush Eggshells: Eggshells add calcium to your compost — crush them first so they break down faster.
