Compost activators or accelerators can be added to the compost to hasten the natural break-down process. They usually contain a natural nitrogen or bacterial enzyme and can be bought at most garden centres.
Sprinkling on lime and untreated wood ash can help balance pH & reduce smells.
The heap should be as moist as a wrung out sponge. Add water if needed.
Avoid excessive moisture by keeping the heap covered.
To work properly, your compost heap needs to reach temperatures between 30 and 60°C. From time to time, check that it is heating up in the centre; it should feel warm.
Compost needs air turn and mix it up to aerate and speed up decomposition.
