Horticultural Database Introduction
Worm composting is an environmentally-friendly way to recycle organic household waste into a valuable soil conditioner called worm compost (vermicompost). It is a FUN and EASY way for people of all ages to recycle their organic waste.
Why should I try worm composting?
- Worms compost quickly: they can eat up to half their own body weight in waste every day.
- Worm composting can be undertaken all year round and requires only minimal effort and a little knowledge. It is an excellent way to increase the environmental awareness of children.
- The worm compost produced can be used in the garden. It will return nutrients and organic matter to the soil, which improves fertility, structure, moisture retention and drainage as well as encouraging plant growth.
- Recycling organic household waste with a wormery helps to reduce the amount of rubbish transported to landfill. It is a simple, cost-effective, way of recycling organic waste.
Starting a wormery
Wormeries provide the ideal moist, well-ventilated environment that worms require to work most efficiently. - A wormery is relatively easy to establish and there are various different designs.
- The wormery often consists of at least two compartments; a lower collection sump for the liquid and an upper composting area where the kitchen waste goes and worms actively work.
The worms
The worms in a wormery are red worms. These worms are native British worms that will do no harm if they escape into the garden. - They are different from garden earthworms, which would not survive in a wormery. Composting worms live in decaying organic matter, whereas earthworms are soil dwellers.
- Worms digest waste with the help of other beneficial organisms to produce worm castings. Unlike compost heaps wormeries do not work at high temperatures.
- A wormery should be started off with around 1000 worms.
- They are safe and hygienic
What do worms eat?
- Any cooked or uncooked fruit and vegetable waste (Potato peelings, apple cores, banana skins, rotten fruit)
- Stale bread, tea bags, eggshells and coffee grounds (in small amounts).
- Paper and cardboard (in small amounts).
- Worms cannot eat plastics, glass or metal.
- Cooked / uncooked meat scraps and dairy products should be avoided.
