Okay, troops. At ease. Let’s talk MULCH. Mulch is important. It is not only aesthetically pleasing, it serves some purposes. Aesthetically, it neatens the appearance of your landscape. It makes your AO (Area of Operation) look more squared away. Mulch really makes your landscape look like you care about the appearance of your quarters or facility. The more functional roles of mulch are: suppressing weeds, retaining moisture, insulating the soil and diminishing soil erosion.
