Here, vermicompost is an excellent option that allows for an indoor composting operation in less space. All you need to do is create a worm bin and throw all your food scraps/wastes for the worms to feed off and make the soil rich. 

There are numerous benefits of Vermicompost over chemical fertilizers like it contains more nutrition and is quite affordable.

Method to make vermicompost at home

Check out the step by step method to make vermicompost at home;

Vermicomposting - Stage I  - Set up Worm Bin 

Step 1 - Select a spot in your home to keep the worm bin

The best places for worm bins keep a consistent temperature & moisture level. So you must not place it near an oven, heater, air conditioner, or vent. Though worm bins generally don't produce much smell, still keep it away from the living areas of your house. Store the worm bin in a laundry room, closet, or other storage room. Those with a large kitchen can place the bin there so as to easily throw food in it. 

Step 2- Buy a worm bin

Worm bins are actually pre-made vermicompost containers. It is available at several gardening or organic supply stores. If you don’t want to purchase a worm bin then get a 20-gallon storage container. Make sure it’s opaque so that light does not get in.  

Step 3- Drill holes in the bin for airflow

In a pre-made worm bin, there will be air holes but if you purchase a storage container then you will have to use a power drill to cut ½ inch holes in the bottom, sides & lid of the bin. Drill around 20 holes in the bin.

Step 4 - Place the bin on blocks with plastic under it 

Get two blocks or, two wood pieces or something else that can keep the bin off the ground. Layout a big sheet of plastic in the area of the house where you want the worm bin. Now put the blocks/woods on the plastic & put the bin on blocks. 

Step 5 - Buy worms online or from a garden store 

The most important step is to buy worms. You may buy it from a nearby garden store or they are also available online.

Vermicomposting - Stage II - Make Worm Habitat 

Step 1 - Cut newspaper or corrugated cardboard for bedding

Worms need bedding that holds moisture well, so newspaper & cardboard are best. Shred enough newspaper or cardboard to fill the bin about 8 inches high. 

Step 2 - Soak bedding with water 

Worms will need moisture to live as well as breath, so it’s important for the bedding to be damp before you add the worms into it. Sprinkle or pour little water on the bedding. Make sure that all of the bedding is wet.

Step 3 - Place the bedding into bin 

When water gets properly soaked in the bedding, spread it evenly across the base of the bin. The bedding must fill at least the bottom 8 inches or so of the bin, so that there is sufficient room for the worms to settle in.

Step 4 – Pour some dirt on top of the bedding  

As the worms naturally live in soil, they will feel more like home in your bin if you put some soil in it. Take some debris-free soil from outside, or buy some regular potting soil from the garden store. Then spread it properly across the bedding. 

Step 5 - Put an even layer of food waste on top of soil 

Spread the food scraps or waste all across the soil. The best food scraps that you can use are leaves, peels, rinds, cores & seeds from fruits & vegetables. Also go for crushed eggshells, tea bags & coffee grounds.

Step 6 - Close the lid & wait for two weeks

Now close the lip of the bin properly for at least 5 to 10 days.

Starting to Vermicompost - Stage III

Step 1 - Place worms into the bedding

Open the cover of the worm bin and make a hole in the middle of the bedding. Put the worms slowly into this hole, rather than across the top. The worms will feel more comfortable this way.

Step 2- Add about 225g of food every day for each 1000 worms

If your family makes more waste then you can add more worms into the bin.

Step 3- Harvest the vermicompost after about 6 months

Check the bin every week to see how much bedding is left. When all the bedding gets converted into compost then you must understand that it’s harvest time. So push it all to one side and add new wet bedding. Slowly dig out the compost but leave the worms in the bin. 

Congratulations you have prepared a great vermicompost at home!!
