Most of us know that mulch has multiple benefits, but not everyone understands what it is. In its simplest form, mulch is any substance used around plants or to cover soil. Let’s take a closer look and what types of material can be used for mulch and what benefits it provides.
Types of Mulch
Generally, mulch can be divided into two categories – organic and inorganic.
- Organic Mulches – Examples of organic mulches include straw, wood chips, leaves, grass clippings, straw, eucalyptus bark and sawdust.
- Inorganic Mulches – These mulches consist of non-living materials including sand, gravel, pebbles, weedmat, black plastic, landscape fabric and crushed rock.
Benefits of Mulch
No matter what type of mulch you choose, mulching has many benefits. These include:
- Control weeds – mulch blocks out sunlight which impedes weed growth.
- Locks in moisture – soil dries out quickly in summer which isn’t good news for your plants. Mulch protects your soil by creating a blanket-like effect and reducing the rate of evaporation by up to 60 per cent.
- Keeps an even soil temperature – The blanket effect of mulch protects it from extremes of temperature and adds stability. Whether it’s extreme cold, rain, wind or heat, your soil temperature will be moderated and protected from erosion.
- Maintains nutrient levels – as the mulch breaks down nutrients and humus are added to the soil. Humus is the organic matter in soil. It supports worms and microbes which in turn keep your soil healthy.
