Black plastic is extremely beneficial for use beneath inorganic or organic mulch. The plastic does not allow any air or sunlight through, which kills any weeds or unwanted plants beneath it. It also prevents future unwanted plants from occurring. When properly laid, the plastic also helps retain an even ground temperature, which can be ideal for growing certain varieties of plants.

Can you use garbage bags under mulch?

Garbage bags can be used in regular mulching because they will effectively smother weeds and hold moisture in the soil. However, because the plastic is less porous than organic types of mulch, it means less water and fewer nutrients will reach the soil itself from above the layer of plastic bags.
