Can I Compost This? Guide to Compost Do’s and Dont’s

Whether you are a keen composter or a beginner who is excited to get started, there are few rules to follow when it comes to composting. To ensure that your compost heap is more than a pile of rotting household rubbish and is actually viable for your garden, you need to be aware of what you can and can’t add to the pile. Adding the non-compostable items can lead to your compost pile becoming smelly, attracting pests, and unable to break down.

The basics of composting

Composting is the process of natural decomposition in which organic materials break down to become nutrient mulch which is great for your garden. For your compost to be a success, you need a combination of carbon-rich materials, known as ‘browns’, and nitrogen-rich materials, which are called ‘greens’. Your compost also requires oxygen and water, which are infused by turning your heap weekly and by adding moisture.
