Mastering Composting: From Kitchen Waste to Garden Gold
Did you know that nearly 60% of your daily household dustbin is just food scraps? Instead of throwing it away, you can turn it into Black Gold—the best food for your plants. It costs nothing and reduces garbage that goes to Indian landfills.
Here is how you can start composting at home today.
The Basic Formula: Greens + Browns
Composting is like cooking; you need the right recipe. You only need two ingredients:
The Greens Nitrogen
This is your wet kitchen waste.
The Browns Carbon
This is dry waste that absorbs moisture and prevents bad smells.
Step-by-Step Guide
Choose Your Container
You do not need expensive equipment.
DIY Method:
Take an old plastic bucket or a paint bucket. Drill 4-5 small holes around sides near top for air circulation.
Terracotta Pot:
You can use three stacked earthen pots (often called a Khamba), which looks nice on balconies.
The Spot: Place the bin in a corner of your balcony or garden where rain would not enter it directly.
Start Layering (The Sandwich Method)
Think of your compost bin as a sandwich.
Bottom Layer:
Start with a 2-inch layer of Browns (dry leaves or crushed cardboard) at the bottom. This helps airflow.
Add Greens:
Dump your daily kitchen peels and scraps on top.
Cover with Browns:
This is the most important step. Always cover your fresh wet waste with a layer of dry waste (Browns). This stops flies and prevents bad smells.
Add Magic Potion
To speed up the process, you need microbes. You do not need to buy expensive powders.
Sprinkle a little sour buttermilk (chaas) or a mix of jaggery and water over the pile once a week. This acts as an accelerator.
Aerate (Let it Breathe)
Once a week, give the pile a mix with a trowel or a stick. The microbes need oxygen to work. If you do not mix it, the pile might start to smell.
The Harvest
In Indian heat, your compost will be ready in 45 to 60 days.
It is ready when it looks like dark, crumbly earth and smells earthy (like first rain). Sieve it if you want fine powder, or use it as is!
The Safe List vs. The No List
For a beginner, stick to this list to ensure your compost never smells bad.
Cooked Food:
No curries, dal, or rice (they attract rats and cockroaches).
Dairy:
Milk, ghee, cheese, or curd (causes bad smell).
Meat & Bones:
Takes too long to break down and attracts pests.
Pet Poop:
Never put dog or cat waste in compost used for food plants.
Troubleshooting Common Issues
Problem: It smells like rotten eggs.
Reason:
Too wet and not enough air.
Fix:
Add a lot of dry leaves/cardboard (Browns) and mix it well.
Problem: It is too dry and nothing is happening.
Reason:
Not enough moisture.
Fix:
Sprinkle some water or add more vegetable peels.
Problem: Too many fruit flies.
Reason:
Exposed fresh food.
Fix:
Cover the top layer with a thick layer of dry leaves or a newspaper.
How to Use Your Black Gold
Once ready, mix this compost with your regular garden soil. A good ratio is 1 part compost to 3 parts soil. Your plants will grow faster, greener, and healthier without any chemical fertilizers!
