What Is Composting?
Composting is the natural process of breaking down organic material into a dark, crumbly substance called compost. This happens with the help of microorganisms, air, moisture, and time. The finished compost can be used to improve soil structure, feed plants, and increase water retention.
What You Need to Start Composting
You can compost using:
- A compost bin (plastic or wooden)
- An open compost heap
- A compost tumbler
- A wormery (for food waste)
Place your compost bin:
- Directly on soil (not concrete)
- In a well-drained area
- Somewhere easy to access all year
What Can Go in a Compost Bin
Good compost relies on a balance of green and brown materials.
Green Materials (Nitrogen-Rich)
These help compost break down quickly:
- Fruit and vegetable peelings
- Grass clippings
- Coffee grounds and tea bags
- Plant trimmings
- Annual weeds (without seeds)
Brown Materials (Carbon-Rich)
These add structure and airflow:
- Cardboard and paper (torn up)
- Dry leaves
- Straw or hay
- Egg boxes
- Wood chips or sawdust (small amounts)
Aim for roughly 50% greens and 50% browns.

What Not to Compost
Avoid adding:
- Meat or fish
- Dairy products
- Cooked food
- Oil or fat
- Diseased plants
- Pet waste
- Glossy paper or treated wood
These can cause smells, attract pests, or spread disease.
How to Build a Compost Heap
- Start with a layer of coarse material (twigs or straw) for airflow
- Add alternating layers of green and brown waste
- Keep materials moist but not wet
- Chop large items to speed up breakdown
- Add new waste little and often
Turning and Maintaining Compost
- Turn compost every 2–4 weeks if possible
- Turning adds air and speeds up decomposition
- Compost should feel like a damp sponge
If it smells bad, add more brown material and turn it.
If it’s dry and slow, add water and more green material.
How Long Does Compost Take?
- Actively managed compost: 3–6 months
- Left untouched: 9–12 months
Finished compost is:
- Dark brown or black
- Crumbly and soil-like
- Earthy smelling
- Free from recognisable food scraps
How to Use Finished Compost
Use compost to:
- Improve garden soil
- Mulch around plants
- Fill pots and containers (mixed with soil)
- Boost vegetable beds
- Improve lawn condition
Common Composting Problems
Bad smell: Too wet or too many greens
Slow breakdown: Too dry or not enough greens
Flies: Exposed food waste – cover with browns
Rats: Avoid cooked food and meat scraps
Most problems are easily fixed by adjusting the balance.
Is Composting Worth It?
Absolutely. Composting:
- Reduces household waste
- Saves money on compost
- Improves soil health
- Encourages sustainable gardening
Once started, it quickly becomes a natural part of gardening.
Final Thoughts
Composting is simple, rewarding, and incredibly beneficial for your garden. With the right balance of materials and a little patience, you’ll produce rich, free compost that your plants will thrive on — all while reducing waste and helping the environment.
