Composting: Step by Step Beginners Guide
Compost is nature's recycling system. It transforms kitchen scraps and garden waste into nutrient-rich soil that plants love. You'll reduce your waste while getting free, quality fertilizer for your garden.
Info
Composting is one of the easiest steps toward sustainable living. It's good for both nature and your wallet!
What is Compost?
Compost is a humus-rich soil amendment created by microorganisms breaking down organic waste.
Benefits of Composting
- Improves soil structure: Aerates and increases water retention
- Provides nutrients: Nitrogen, phosphorus, potassium, and trace elements
- Reduces waste: 30-40% of household waste is compostable
- Saves money: No need to buy fertilizer and soil amendments
- Carbon footprint: Organic waste in landfills produces methane gas
Before Starting: Basic Concepts
Green and Brown Materials
For successful compost, "green" (nitrogen-rich) and "brown" (carbon-rich) materials must be balanced.
| Green Materials (Nitrogen) | Brown Materials (Carbon) |
|---|---|
| Vegetable/fruit scraps | Dry leaves |
| Fresh grass clippings | Cardboard, paper |
| Coffee grounds | Wood shavings |
| Eggshells | Straw, stalks |
| Fresh weeds | Small branches |
| Tea bags | Newspaper (uncolored) |
Garden Tip
Golden ratio: 3 parts brown to 1 part green material. This balance ensures fast and odorless composting.
Materials NOT Suitable for Compost
Warning
Do not add these materials to your compost bin:
- Meat, fish, dairy products (odor, pests)
- Oily foods (won't decompose)
- Diseased plants (spreads disease)
- Pet waste (pathogens)
- Weed seeds (may spread)
- Hard fruit pits (takes too long to decompose)
Choosing a Compost Bin
1. Open Pile
The simplest method - make a pile in a garden corner.
Pros
- No cost
- Unlimited capacity
- Easy material addition
Cons
- Visual clutter
- May attract pests
- Slow process
2. Compost Bin

$449
Pros
- Very fast compost (4-6 weeks)
- Pest-proof
- Easy mixing
- Clean and tidy
Cons

Composting: Step by Step
- 1
Choose Location
Select a spot with partial shade, good drainage, and near a water source. Full sun dries out too quickly. - 2
Prepare the Base
Lay thin branches and coarse material at the bottom of the bin or pile. This ensures air circulation. - 3
Create First Layer
Start with 10-15 cm of brown material (dry leaves, cardboard). - 4
Add Green Material
Add 5-10 cm of green material (kitchen scraps, grass). - 5
Repeat Layers
Alternate brown-green layers. Sprinkle a bit of soil on each green layer. - 6
Moisten
Lightly water after each layer. Moisture level should be like a squeezed sponge - damp but not dripping. - 7
Cover
Cover with dry leaves or cardboard. This prevents moisture loss.
Maintenance and Monitoring
Turning
| Method | Turning Frequency | Result |
|---|---|---|
| Open pile | Every 2-4 weeks | 6-12 months |
| Bin compost | Every 4-6 weeks | 4-6 months |
| Tumbler | 2-3 times weekly | 4-6 weeks |
| Vermicompost | No turning needed | 2-3 months |
Moisture Control
Garden Tip
Ideal moisture: Like a squeezed sponge. When you squeeze a handful of compost, a few drops should drip out and it should crumble.
- Too wet: Add brown material, turn
- Too dry: Add water, cover top
Temperature
Active compost heats up! Temperature:
- 40-60°C: Ideal, fast decomposition
- 20-40°C: Normal, slow process
- 60°C+: Too hot, add air and water
Common Problems and Solutions
Bad Odor
Cause: Too much green material, insufficient air
Solution:
- Add brown material
- Turn thoroughly
- Leave top open (temporarily)
Compost Not Heating/Cold
Cause: Insufficient nitrogen or moisture
Solution:
- Add green material (grass, kitchen scraps)
- Check moisture
- Make pile smaller (if too large)
Pest Problem
Cause: Meat, oily food, or open pile
Solution:
- Remove prohibited materials
- Use lidded bin
- Bury kitchen scraps
Mold/Fungus
Cause: Excessive moisture
Solution: Normal! Small amounts of mold are part of the compost process. If excessive, add brown material and turn.
When is Compost Ready?
Mature compost characteristics:
- Color: Dark brown to black
- Smell: Earthy smell (no rotting odor)
- Texture: Crumbly, loose
- Temperature: Ambient temperature (not heating)
- Appearance: Original materials unrecognizable
Info
Duration: 2 months to 1 year depending on method and conditions. Tumblers give fastest results.
Using Compost
Application Rates
| Use | Rate | Notes |
|---|---|---|
| Soil amendment | Mix 20-30% | New bed preparation |
| Top dressing | 2-5 cm layer | Annual maintenance |
| Potting soil | Mix 25-30% | With fresh soil |
| Lawn topdressing | 1 cm layer | After aeration |
| Mulch | 5-8 cm | Around roots |
When to Apply?
Spring Tip
Mix into soil before spring planting. Ideal preparation for summer vegetables.
Fall Tip
Add compost to beds after removing end-of-season plants. Matures over winter.
Accelerating Tips
For Faster Compost
- Shred materials: Smaller pieces decompose faster
- Turn frequently: Weekly turning speeds up process
- Maintain moisture: Prevent drying out
- Use activator: Add compost activator or mature compost
- Maintain green-brown balance: 3:1 ratio
