When mowing your lawn, there are benefits to mulching your clippings as opposed to bagging them:
The benefits of mulching your lawn is that the mulch consists of mowed grass clippings.
The clippings are cut into fine pieces that fall easily to the soil surface.
There, they can be rapidly broken down by microorganisms within the soil, which release nutrients from the mulched plant material back into the soil.
As the finely cut pieces decompose easily at the soil surface, they are recycled by the microorganisms for nutrients.
The nutrients from the broken down mulched plant material becomes an organic fertilizer.
The mulch clippings also serve as a blanket and help with water retention.
The lawn clippings gather at the base of the soil allowing the soil to retain moisture and allow for less watering time between watering cycles.
