Composting at home is one of the best ways to utilize any kitchen scraps, newspaper, and other compostable materials you have at home to reduce overall food waste and even help the environment!
One of the loveliest aspects of nature is that everything in it has a use โ the nasty, rotting zucchini as well as the lavender sprouting scented blossoms in the backyard.
Home composting can take some of our leftovers, waste, and unwanted extras and turn them into fertile soil to boost the productivity of gardens and landscapes.
In this guide, we’ll show you how to compost at home easily step by step. Specifically designed to maximize the process with a minimal amount of effort.

What is Compost?
Compost is decomposed organic material that is produced when bacteria in soil break down garbage and biodegradable trash, resulting in a product rich in minerals that is an ideal garden or landscaping amendment.
In fact, itโs natureโs perfect amendment and can be added to the soil any time of year without the fear of burning plants or polluting water.
Benefits of Composting at Home
- For one, itโs free. You get to use kitchen waste, lawn clippings, leaves, and other vegetation that would otherwise get thrown away. In fact, you might even save money on landfill fees.
- Potting mixes and soils that are rich in compost produce vigorous plants regardless of whether youโre growing vegetables, growing herbs, or organic rose gardening.
- Improves garden soil structure, texture, and aeration.
- Adding compost improves soil fertility and stimulates healthy root development in plants. The organic matter provided in compost provides food for microorganisms, which keeps the soil in a healthy, balanced condition.
- Compost loosens clay soils and helps sandy soils retain water
- No need to add fertilizer โ just mix compost into the soil. Compost contains nutrients that plants need for optimum growth, such as nitrogen, phosphorus, and potassium. And itโs an especially good supplier of micronutrients that are needed in small quantities such as boron, cobalt, copper, iodine, iron, manganese, molybdenum, and zinc.
- It feels good. When else can you turn trash into treasure? Plus, scraps stay out of the landfill, reducing your footprint.
How Does Composting Work?
You mix yard and kitchen waste in a pile or bin and provide the right conditions to encourage decomposition.
Let bacteria and fungi go to work recycling waste material into fertilizer.
Mix compost into garden soil or use it on the surface as mulch.
Sounds simple, right? Well, it is. Microbes are hard at work chomping down your throwaways. You supply the organic materials, water, and oxygen. The bacteria that are already there decompose the plant material into compost. As the bacteria break down the materials they release heat, which is concentrated in the center of the pile. ย Keep your pile cooking with this 20-inch long, stainless steelย thermometer.

How to Compost at Home Step by Step
Everyone has a different level of commitment when it comes to composting.
For some, a rot pile in the backyard is good enough. Others want to apply the rigors of science and constant vigilance to ensure the best (and quickest) compost around.
Most of us are somewhere in between. Regardless of your level of experience, Planet Natural offers a wide selection of composting bins, tumblers, and supplies to get you started.
Use the steps below as a guideline for how to compost. The more you follow them, the better your finished product will be.
1. Select a site for your pile or bin
To keep your neighbors happy, consider a discreet location. Youโll also want to locate a spot with good airflow, access to water, and partial shade in the summer (to keep the pile from getting too hot), but good sun in the winter (to keep the pile warm).
2. Choose a bin
You can purchase a composter, or make your own. Rotating bins make turning your treasure easy and keep animals out, but it is easy to make a workable bin on your own (see How to Build a Compost Bin). One simple method is to track down shipping pallets. Use one for the bottom. Pound in metal support poles and add pallets by slipping them over the support poles to make your binโs walls.
Make your pile about 3x3x3 feet. This size is big enough to create its own heat but small enough to turn. If you are using a commercial composter you wonโt need to worry about the size. Efficient and affordable, SoilSaver features anย award-winning design.

3. Add compostable materials
Not everything can go into the compost bin; read on to find out what can and cannot be composted.
What to Compost
Composting can be done with a wide range of organic materials, such as food scraps, lawn trimmings, and many other things. Here are some things that you can compost:
- Fruit and vegetable peels and scraps
- Rotten fruit and veggies
- Houseplant trimmings
- Coffee grounds and paper filters
- Loose tea leaves and tea bags
- Eggshells
- Nutshells (excluding walnuts)
- Paper, cardboard, and shredded newspaper
- Napkins, paper towels, and unused toilet paper
- Cotton and wool rags
- Hair and fur
- Grass clippings
- Leaves
- Flowers
- Hay and straw
- Sawdust
- Wood chips
- Yard trimmings
What Not to Compost and Why
Not every thing from your kitchen or garden needs to go in the compost. In fact, certain things could draw insects, pests, and rodents while others might contain harmful toxins. Here are some things you should avoid composting:
- Bones or scraps from meat, fish, and poultry: Produces odor, attracts pests, and might also carry pathogens.
- Dairy products: Produces odor and attracts pests
- Leaves or twigs from black walnut trees: Releases a compound thatโs toxic to plants
- Walnuts: Releases a compound thatโs toxic to plants
- Coal ash or charcoal: Contains compounds that may harm plants
- Large pieces of wood: May take a long time to decompose
- Fat, cooking oil, and grease: Creates odor problems and attract pests such as rodents and flies
- Yard trimmings treated with chemical pesticides: May kill microorganisms needed for the composting process
- Coffee pods: Most contain plastic and donโt break down naturally
- Baked goods:May attract pests and increase the growth of harmful bacteria
- Plants that are diseased or infested with insects:Diseases or insects might survive and be transferred back to other plants
- Pet waste, such as feces or litter: Might contain parasites, bacteria, germs, pathogens, and viruses harmful to humans
4. Monitor four key elements of composting
It’s important to monitor temperature, aeration, moisture, and the carbon to nitrogen ratio for optimum levels. An easy and effective wayย to mix and add oxygen toย the pile without heavy lifting.

I) Temperature
The easiest way to test your compostโs temperature is to stick your hand in the center of the pile. If it is hot or warm โ good job. If it is the same temperature as the ambient air, the microbes have slowed down โ and so has the composting process.
II) Moisture
The microbes hard at work in your compost pile require just the right amount of water. Too much means organic waste wonโt decompose, too little and youโll kill the bacteria. Compost should feel moist, but not soaking wet โ like a wrung-out sponge.
Composting works best with 40-60% moisture content. More on monitoring compost moisture here.
III) Carbon to Nitrogen Ratio
For perfect compost, maintain a C:N ratio of 25 to 30 parts carbon to 1 part nitrogen, or 25-30:1. If the C:N ratio is too high (not enough nitrogen) decomposition will slow down. If the C:N ratio is too low (not enough carbon) youโll end up with a smelly pile.
Read our article Carbon-to-Nitrogen Ratios to learn more about reaching this perfect balance between brown and green compostable materials.
In general, carbon-rich materials (browns) include dried leaves, newspaper, straw, and nitrogen-rich materials (greens) include vegetable scraps, garden waste, and grass clippings.
IV) Aeration
Everyone needs to breathe, even tiny microorganisms, so make sure enough oxygen is getting into your pile by turning your compost often.
If the compost pile is warm to the touch or registers between 130 and 150 degrees Fahrenheit on a thermometer, it is time to give it a turn. Stirring the compost pile speeds up the cooking process and keeps items from becoming matted and generating an odor.
The brown and green layers have served their role at this stage, so it’s safe to completely combine the two components.
Use a compost aerator or pitchfork to mix your pile. If you are using a compost tumbler, youโve got it easy. Just crank that lever.
If you are using easily compacted materials (such as ashes or sawdust) mix in coarser materials first. People who build large piles often add tree branches or even ventilation tubes vertically into different parts of the pile to be shaken occasionally, to maximize air circulation.
5. Mix and Use
Mixrich, earthy compost into garden soil, or pile it on top of the soil as mulch.
Tips & Techniques for Composting at Home
Here are a few more tips to turn carrot tops (and anything else) into compost more quickly:
- Help start a new compost pile with blood meal, cottonseed meal, well-aged manure, or compost starter. They are rich in nitrogen and help โfire-upโ the microbes responsible for breaking down organic matter into compost.
- Chop or shred materials before putting them in the compost pile or bin. The smaller it is, the faster it will break down.
- Use a kitchen compost pail or crock for storing food scraps. It will reduce the number of trips you make to the compost pile.
- Plants that have been treated with pesticides and/or herbicides (weeds and lawn clippings) should be avoided.
- Add a lot to your pile at once, rather than in small doses to encourage the pile to heat up.
- Turn, turn, turn. Turning compost will introduce oxygen and speed up the composting process.
- Keep your pile or bin in the sun. Microbes are more active when warm.
- Activators can get a slow compost heap sped up.
- Got compost? When finished it should look, feel and smell like rich, dark soil. You should not be able to recognize any of the items you put in there.
- Finished compost is usually less than half the volume of the materials you started with, but itโs much denser.
- Apply finished compost to your garden about 2-4 weeks before you plant, giving the compost time to integrate and stabilize within the soil.
