What is composting? A quick explanation
Composting is the process by which organic materials, such as fruit and peel, decompose to produce a soil-boosting end product known as compost. There are two types of composting: cold and hot.
Cold composting is the process of collecting garden waste, and organic materials from your kitchen, such as fruit, vegetable peels, eggshells and coffee grounds and filters. You place them into a bin, and within a year or so the material decomposes to produce compost.
Hot composting is a faster process (it can take between 1 and 3 months instead of over a year). You require 4 ingredients: nitrogen, carbon, air and water (they help in the decay process). However, we recommend this process for experienced gardeners only.

- What to compost.There are a number of items that you can add to your compost, these include:
- Fruit scraps such as banana and orange peel
- Vegetable scraps such as carrot peel

- Dry leaves
- Finely chopped wood and bark chips
- Shredded newspaper
- What not to compost. Here are a few things you should avoid adding to your compost:
- Meat and oils used to cook meat (these will attract rodents and other pests)
- Diseased plant materials, this will affect your final compost so it can’t be used to help grow plants in the future
- Pressure-treated wood
- Dog and/or cat faeces
- Weeds that go to seed such as dandelions
- Dairy products.
- Combine your green and brown ingredients. Brown materials are those such as fallen leaves and straw (which add carbon). Green materials are those such as kitchen scraps, horse manure and grass trimmings (which add nitrogen). The best ratio for compost is 3-parts brown and 1-part green.
- Keep the compost damp. You should take care that compost isn’t waterlogged, as this will kill essential microorganisms that help the decomposition process.
- Turn your compost. Check the temperature of your compost. When it reaches between 50-65 degrees Celsius, it’s time to turn the pile.
- When is your compost ready? The compost is ready to use to feed your garden when it no longer gives off heat. It will become dry, brown and crumbly and look more like soil than scraps.
Now you have a simple guide for how to make compost, including what you can (and can’t!) use, and should have an understanding of why it’s beneficial. With these easy steps, you can now start to create this must-have product and keep your garden healthy.
