Mulch is generally defined as a material that is used to cover the ground soil to avoid the latter from water loss due to evaporation, to minimize erosion, and to retard (or totally prevent) the growth of unwanted plants in the garden.
Let’s detail the main advantages of using Mulch in your garden one by one.
Advantages of using Mulch in Garden
1# Prevents Water Loss
First, mulch prevents water loss in the garden. When the ground is exposed to direct sunlight, the water that is stored within it evaporates. The loss of soil moisture is dangerous for plants that live in it, as water is an essential nutrient for plants to grow well.
Furthermore, beneficial microorganisms like nitrogen-fixing bacteria also need moisture for them to survive.

2# Minimizes Soil Erosion
Second, mulch minimizes soil erosion. Top soil is considered as the most fertile part of the garden. However, when soil erosion happens when there are heavy rains or strong winds, the topsoil either gets washed off or blown away.
Mulch, when applied on top of top soil, adds pressure on it which lessens the likelihood of having the topsoil eroded by running water.
Moreover, it also acts as a shield so that the topsoil doesn’t dehydrate fast when subjected to strong winds, which is the main reason why it gets blown away.
3# Prevents Growth of unwanted Plants
Lastly, mulch prevents the growth of unwanted plants, like weeds, in the garden. Mulch, as we already know, covers the topmost layer of soil. This prevents sunlight from reaching the fertile topsoil, which in turn prevents weeds and other unwanted plant species from growing in it.
Because of this, seedlings that we ourselves have planted on the soil will grow better, as they can take advantage of the full potential of the ground soil without having to compete with too many neighbors.
