In the preceding discussions, there have been several references to conventional turf grass or Kentucky Bluegrass turf. This type of ground cover is not necessarily bad to have as a landscape covering. The main concern is its inherent need for water. There are many reasons for a conventional turf grass yard as well as many benefits. One of the major benefits is the reduction of allergy-related pollens in the immediate environment. Another is the clean up of groundwater recharge and surface water.
Please keep in mind that one of the most common mistakes with conventional turf grass lawns is over watering. A good base of well-maintained black dirt (topsoil) is the best way to reduce the amount of water needed to produce a healthy turf grass ground covering.
