What is Vermicomposting?

Vermicomposting is using earthworms to break down compostable materials instead of leaving it to mother nature. The worms eat the leftovers and as it passes through their body leaving behind “casings” which are nutrient rich and make excellent soil.

How to Get the Best from Vermicomposting

Make sure your worms have everything they need. By this, I mean don’t just open the top of your compost heap and dump worms on top then expect them to be happy and start munching their way through your waste. Add them into the middle of your pile gently and make sure the compost or materials already in place are well mixed and ventilated. There should be plenty of room for your worms to wriggle about in.

Your heap should be at least eight to twelve inches deep and the surround of your bin should be made from wood or a hard wearing material.

Add in bedding material that is damp but not wet. Worms like a home that is about 75 per cent water and the rest waste. This doesn’t mean you can dump gallons of water on your compost heap and hope for the best, but definitely worth remembering in the summer that you have living creatures in your compost and they would like some moisture. The best sort of bedding material is shredded newspaper or cardboard. Worms also don’t like lots of noise or vibrations, if you can put your bin in an area that is quieter and away from traffic noise or other nuisances.

You should also add gritty materials like sand and crushed eggshells to your compost heap as this helps the toothless worms break down the composting materials. And be sure to wear some really good gardening gloves to prevent the spread of dirt, germs, and things like E.coli or salmonella.

What to Look for in the Best Vermicomposting Bin

Added features on some composters include trays which separate out the castings from the compost materials and even a little tray to collect “worm tea” which is the liquid left behind after vermicomposting. These are well worth investing in if you can as they make the process much lower maintenance.

indoor worm composter

Location – Indoor

First thing to think about is if you have the space and where you are going to store your bin. If you want it to be inside your home, think about where it will go and whether you want it to be tucked away or part of the furniture and decor. If it is going to be on display, it might be worth investing in a well designed and attractive looking bin to make sure it fits into your home. Also, worth thinking about is odor. An indoor composter will smell a little it as the worms do their thing but you can get models with odor control to lessen this effect.

outdoor worm composter

Location – Outdoor

Outdoors, you want to make sure the bin you choose suits the size and shape of your garden. If you want it to blend in, choose a dark green model and perhaps plant some shrubs around it or a black version tucked into a nook or corner will melt out of sight.

hardwearing weather-resistant plastic resin


Material is also very important when you’re investing in an outside bin. As most of us don’t want the hassle of trying to move a full compost bin (complete with worms!) into the house or garage through the winter months, finding a sturdy bin that will survive extremes of temperatures is really important. Choose a strong plastic or resin that is specifically designed to withstand freezing or heat to make sure your bin is ok to stay outside all year round.


Another thing which really helps worms get to work is ventilation. Make sure your compost bin has holes running through it or a domed lid to encourage ventilation and ensure your little worms are getting enough air.

Added Features such as trays

Added features on some composters include trays which separate out the castings from the compost materials and even a little tray to collect “worm tea” which is the liquid left behind after vermicomposting. These are well worth investing in if you can as they make the process much lower maintenance.

How Many Worms Will I Need?

A good rule of thumb is to get about 2,000 worms for every pound of food waste. As 2,000 worms weighs about two pounds, try to have around half the amount of worms for your waste products. If you start out with a small amount of worms, you can just add less to your bin until they increase and you can add more.
