Composting is easy in summer. Temperatures are high and there's an abundance of soft green material that will break down quickly when blended with woody prunings. By contrast, in winter, the temperature at the core of your heap can drop to the point where decompostion stops altogether.
The rotting process in a well-made heap will generate its own heat. Insulation, such as flattened cardboard, old carpet or polythene sacks filled with straw will help retain this heat. It's also important to stop the winter heap becoming overly wet, so covering the bin is vital.
The secret to perfect compost is to get the right ingredients well mixed or layered. Follow our tips for success, below.
