What is mulching?
In ecological horticulture, mulch refers to organic matter – such as leaves or grass cuttings – that is applied to the soil to protect it and supply it with nutrients. Mulching is the process of doing so by adding a loose layer of shredded plant material on top of the soil. Mulching is a valuable method to use in almost every area of your garden, and for home gardeners it’s also a great way to save time, money and effort.
How does mulching work?
Mulching helps soil retain moisture by shading the earth and acting as a blanket. It means water can be stored more effectively in the ground, so the soil remains loose and will not dry out too quickly. Mulching also helps plants to grow by forming a protective layer against heavy rain and cold temperatures. Over time, plant matter used for mulching is broken down by earthworms and soil-dwelling organisms into valuable natural fertilisers and nutrients for plants.
What is mulching material?
Mulch can be made of a range of natural materials, ranging from soft grass clippings, to chipped bark, to hard matter such as gravel or shells. Different materials should be used in different areas, depending on what benefits and nutrients the area you are mulching needs.
