The Basics
Many people use the words soil and compost interchangeably however there is a big difference between them. Compost is a mixture of vegetable waste and decayed plants which is used to fertilise and enrich soil and plants. Soil is the thin layer of material covering the Earth’s surface. It is made up of mineral particles, organic materials, air water and living organisms.
You should always use soil to plant your plants as this is what holds the nutrients and water that is necessary for plant survival.
Compost can be spread along the surface of soil or alternatively it can be mixed down through it, it will fertilise and enrich the soil and plants.
Soil that has compost added to it has fewer pest and disease problems.

No, it does not go bad, however it can lose structure and nutrition over time.
The general rule of thumb is 1/4 to 1/2 inch if applying to the top of the soil and 1 to 2 inches amended to 6 to 8 inches when amending into the soil. Recommended maximums are 25% to 30% compost in a soil blend, but no more than 25% compost in containers or raised beds.
Ensure compost is stored in a cool dry place. To store correctly, you will need to cover it, using a tarp, lidded bin, or in a bag, while still allowing airflow to enable oxygen to allow the composting process to continue. Without airflow, your stored compost will break down much slower.
