Everyone Has One and Uses It. How to Compost Properly?

Composting is one of the most natural and efficient ways to recycle organic waste from your garden and household. A properly maintained compost bin not only reduces the amount of waste you need to dispose of, but also provides you with high-quality compost that's perfect for improving soil and nourishing your plants. Let's take a look at how to compost properly so you can achieve the best results.

What is Composting and Why is it Important?

Composting is the natural decomposition process of organic materials by microorganisms, fungi, and other creatures. The result is nutrient-rich compost that you can use as a natural fertilizer for your garden. Composting helps reduce landfill waste, decreases methane emissions, and returns valuable nutrients back to the soil.

Benefits of Composting:

  • Waste reduction – up to 40% of household waste can be composted
  • Soil improvement – compost enriches soil with nutrients and improves its structure
  • Money savings – you don't need to buy expensive fertilizers
  • Environmental support – reduces carbon footprint and supports biodiversity

How to Start Composting?

Starting composting is easier than you might think. All you need is a suitable location, a compost bin or pile, and basic knowledge about what belongs in the compost and what doesn't.

Choosing the Right Location

The ideal place for a compost bin is a shaded or semi-shaded spot with good drainage. Direct sunlight can dry out the compost too quickly, while complete shade might slow down the decomposition process. The compost should be easily accessible so you can regularly add new materials and turn it.

Types of Compost Bins

You can choose from several types of compost bins:

  • Wooden or plastic bins – suitable for smaller gardens
  • Compost heaps – ideal for larger quantities of organic waste
  • Composters with lids – protect the contents from pests and speed up decomposition
  • Worm composters – perfect for indoor composting in apartments

What Can Be Composted?

The key to successful composting is the right mix of materials. You should combine "green" materials rich in nitrogen with "brown" materials rich in carbon.

Green Materials (Nitrogen):

  • Fresh grass clippings
  • Vegetable and fruit scraps
  • Coffee grounds and tea bags
  • Fresh plant clippings
  • Weeds (without seeds)

Brown Materials (Carbon):

  • Dry leaves
  • Shredded branches and twigs
  • Straw and hay
  • Cardboard and paper (unprinted)
  • Sawdust and wood shavings

What Doesn't Belong in Compost:

  • Meat, bones, and fish
  • Dairy products
  • Fats and oils
  • Diseased plants
  • Pet waste
  • Chemically treated materials

How to Maintain Compost Properly?

Composting isn't just about throwing waste into a pile. Regular maintenance is the key to quick and quality decomposition.

The Right Ratio of Materials

The ideal ratio is approximately 2:1 or 3:1 of brown to green materials. Too much green material can cause the compost to smell unpleasantly, while too much brown material slows down the decomposition process.

Moisture

The compost should be moist but not waterlogged. The ideal moisture level is similar to a wrung-out sponge. If the compost is too dry, add water or fresh green materials. If it's too wet, add more brown materials and turn the pile.

Aeration

Regular turning of the compost is essential for proper aeration and speeding up decomposition. Turn the compost at least once every two weeks using a pitchfork or special aerator. This brings oxygen to microorganisms that need it for efficient work.

Temperature

A properly functioning compost reaches temperatures between 50-70°C in its center. This temperature kills weed seeds and pathogens. If the compost isn't heating up, it may lack nitrogen (add green materials) or be too dry.

When is Compost Ready?

Quality compost is ready after 3-6 months in summer or 6-12 months during cooler months. Finished compost has a dark brown color, crumbly structure, and pleasant earthy smell. Original materials should be unrecognizable.

How to Use Finished Compost:

  • Soil improver – work compost into the soil before planting
  • Mulch – spread a layer of compost around plants
  • Potting mix component – mix with soil for container plants
  • Lawn fertilizer – spread a thin layer over the lawn in spring or autumn

Common Composting Problems and Their Solutions

Unpleasant Smell

If the compost smells of ammonia or rot, there's too much green material or insufficient aeration. Add brown materials and turn the pile more frequently.

Pests

Flies, rodents, and other pests can be attracted to improperly managed compost. Don't add meat, fats, or dairy products, and cover fresh waste with a layer of brown materials.

Slow Decomposition

If the compost isn't decomposing quickly enough, it may lack nitrogen, moisture, or oxygen. Add green materials, check moisture levels, and turn regularly.

Tips for Successful Composting

  • Chop materials – smaller pieces decompose faster
  • Layer materials – alternate green and brown layers
  • Add compost activator – special products speed up decomposition
  • Monitor pH – optimal pH is between 6-8
  • Compost year-round – even in winter, decomposition continues, just more slowly

Conclusion

Composting is a simple, economical, and environmentally friendly way to handle organic waste while gaining quality fertilizer for your garden. With the right approach and regular maintenance, you can enjoy rich, nutritious compost that will help your plants thrive. Start composting today and contribute to a healthier environment for future generations.

Compost is a very high-quality fertiliser that anyone can create at home in their garden. Through composting, bio-waste becomes a material containing humus, which includes organic and mineral substances and water. These substances are then available to plants.

What can be composted?

- fruit and vegetable scraps

- coffee and tea grounds

- bread leftovers

- egg and nut shells

- pet bedding

- grass clippings, leaves and twigs

- sawdust, wood shavings, bark

- wood ash

- pet and livestock manure

- feathers, fur, hair

What not to compost?

- weeds

- bones

- cooking oils and fats

- twigs and plants affected by diseases

- chemically treated materials and plants

What to mix with what?

Follow these basic rules and your compost will always be top-notch.

Mix: wet with dry / porous materials with dense ones / brown with green.

How to do it?

A composter will come in handy for composting, or you can simply layer it in a heap somewhere, just like our grandmothers did. Coarse and airy material should go at the bottom to ensure aeration. Broken branches or woody stems are ideal for this. To get the compost started right from the beginning, you can also add a bit of farmyard manure. Don't forget to add a little soil as well. A properly established compost will start to heat up within a week. That's correct! It means the microorganisms are working. After 1-2 months, the compost needs to be turned over – mixed.

What to check?

Moisture – take a bit of compost in your hand and squeeze it as hard as you can. If no water appears between your fingers – that's correct. When you open your fist, the mass should stick together and hold its shape. If the compost is wet and doesn't hold, turn it over and add dry material. Conversely, if it's dry, moisten it with grey water.

Air – for sufficient air supply, turn the compost over 4-8 weeks after establishing it.

Temperature – higher temperature in the initial weeks after establishing the compost is proof of good composting progress. If the compost doesn't heat up, it's probably too dry or doesn't have the right composition. Another possibility is that there isn't enough of it.

Bonus

You can plant your compost with plants such as pumpkins, courgettes, and cucumbers. The leaves will provide protection from the summer sun, and if it's planted, you definitely won't forget to check whether it needs watering.
