What is a wormery? A Wormery is an easy natural system using worms to convert kitchen food waste into liquid plant feed.
Worm composting is a great way of recycling vegetable scraps, banana skins and tea bags from your kitchen.
A Wormery or worm bin is simply a waterproof container housing a colony of special worms, known as brandlings, tiger worms or redworms. They are ideal for households with small or no gardens, as they produce a liquid which forms a concentrated plant food.
What does a wormery do? It composts waste using special worms known as brandlings, tiger worms or redworms and can be kept indoors. However, is probably best kept outside near your kitchen door or in a shed or garage in the winter. Even if you haven't got a garden, it is great if you want to compost vegetable scraps, and tea bags and other stuff, instead of sending it off to landfill. You will produce a small amount of compost and a liquid, which forms a concentrated plant food and is great for using in pots and containers.
You will be recycling about half of the waste that would otherwise end up in a landfill site. Saving money and reducing the use of chemical fertilisers by using homemade liquid fertiliser.
Components you will need to create a working wormery. You will need about 400 worms, a bag off gritty sand, a couple of perforated bin bags, shredded newspaper and a plastic household waste bin. The bin can be any size. However, the larger the capacity the more worms and kitchen waste you can put into it and the more liquid fertiliser you will get out.
If you intend composting a lot of kitchen waste, it is not the depth that is important. It is the surface area. So, you may be better off constructing a rectangular shaped wormery with a tap fixed into the bottom to draw of the liquid fertiliser. Or if you prefer you can drill holes in the bottom of the bin instead of fitting a tap. You will need to place the bin in a bowl or tray to catch the homemade organic liquid fertiliser.
How to construct a wormery. Drill tiny breathing holes around the top of the bin, not in the lid of the bin, this could let the rain in. Fill the bottom of the bin with 3" of gritty gravel for drainage and place perforated bin-bags over the gravel. Place four inch deep damp shredded newspaper over the bin bags. Drill the tap into the bin just above the gravel. It is a good idea to place the wormery bin on blocks to give enough space to place a container under the tap.
Putting the worms in. Make a small hollow in the shredded newspaper and place the worms inside.
Feeding the worms. Start feeding food scraps to the worms, making sure the scraps are chopped up well and placed no more than about two inches deep across the shredded newspaper. Cover the waste with a couple of sheets of damp newspaper to keep the whole thing moist. You can add more scraps when the previous lot has been eaten. How much you feed will depend on how many worms you have. Practice will make perfect so don't be put of if it gets a bit smelly simply reduce the kitchen waste. composting tips
