Organic fertilising is the balanced natural cycle of giving back to the earth what you have taken out. There are many natural ways to improve the soil in your garden, making leaf mould and composting are two cheap, natural and pollutant free ways of working with your garden, turning household waste into a natural and nutritious garden soil conditioner.
Organic matter helps plants in the soil to grow strong and healthy.
A handy and readily available supply of such organic matter can be found in the garden. Throwing away and burning leaves is a waste, you are throwing away an excellent material that would normally benefit your garden greatly.

Leaf mould is very useful in improving soil structure and as a seed compost. It's free and easy to use.
