Wormeries are a great for composting food waste and small amounts of garden waste, paper and cardboard.

How does it work?
Worms eat the waste material and break it down into compost. Their manure (worm casts) is very beneficial for all soils and plants and can be used as a fertiliser.

The bottom section of the wormery holds excess liquid, which can be used as a liquid fertiliser when diluted with water (at least 10 parts water to one part liquid). This needs to be drained regularly or the container will fill up and drown the worms.


What can I put in it?

Wormeries can only process small amounts of waste at a time.

Food waste such as raw or cooked vegetables, fruit, coffee grounds, tealeaves and eggs shells are great food for the worms.

Avoid meat, fish, dairy products and tougher woody plant materials.

Small amounts of garden waste, paper and cardboard can also be added.

 

Where should I place it?
The ideal temperature for this system is between 15-25 degrees Celsius. If temperatures are low, the worms will be less active and will break down the waste at a slower rate. If it is too warm (above 35) the worms will not be able to survive or will try to escape.
Place your wormery in a sheltered and shady spot and make sure you can access it easily in order to drain the liquid a couple of times a week or wrap it up in cold winter months.

 

Where can I get one?
You can buy Wormeries and starter kits online or in some garden centres
