Composting and worm farming

Composting

Composting breaks down your food scraps and garden waste, and converts it into rich and nutritious soil, by taking advantage of good bacteria and invertebrates (including millipedes and earthworms).

Adding compost to your garden will enrich the soil, adding nutrients and useful bacteria, and help plants grow better with less water.

Worm farming

Worm farms are ideal for people living in flats or houses with small backyards, and is a cheap and easy way to cut down on your rubbish.

Worms quickly and efficiently break down food scraps and garden waste, and produce a rich fertiliser called worm castings, which is great for indoor and outdoor plants, and vegetable gardens.

The most common worms used in worm farms are Tiger Worms, Red Wrigglers and Indian Blues. Worms are available at good hardware stores or plant nurseries.

You can purchase a worm farm from us (just add worms), or you can make a cheaper version by using a polystyrene fruit box with drainage holes underneath.

Tips

• cover the food waste with newspaper or a hessian bag as this will help to keep a constant temperature
• place the worm farm in a shady spot in your garden or garage because worms like an environment that is cool, dark and moist

Steps to composting

1. Put a layer of coarse material such as prunings, dry leaves and shredded newspapers on the base of your heap.
2. Add alternate layers of food scraps or garden waste with soil or compost - like making lasagne - so that it won’t smell or attract flies.
3. Turn it over with a garden fork once a week to speed up the process. After turning it, cover it with soil. The composting material should feel damp. If not, add some water.
4. Add a thin layer of damp shredded paper or cardboard each week, to speed up the process.

Compost tips

To keep your compost heap healthy:

• turn it over with a garden fork once a week to keep air circulating
• chop food scraps finely to speed up the process
• cover the base of your heap with mesh to prevent mice from entering
• add a layer of soil each time you add food scraps to the compost to keep flies away

If your compost:

• smells - it may be too wet so add some ‘browns’ and turn your heap over
• attracts animals - it may contain meat, dairy products, oils or bread
• contains ants - it may be too dry
• is not breaking down - it may not be balanced, so ensure there are equal amounts of ‘greens’ and ‘browns’ types of items

Using compost in your garden

Your compost is mature and ready to use when it feels crumbly and smells like earth. You can:

• dig it into garden beds
• spread it under trees and bushes as mulch
• use it to make potting mix for pot plants or seedlings
