Before starting a new lawn or renovating an old one, several factors should be considered. First, what will the lawn’s use be? Is it strictly for looks or will it be played on frequently by children and/or pets? What is the desired quality level? Will the lawn receive high or minimal levels of maintenance? Is good quality, inexpensive water available? Is the soil sandy or clay-like, and does it drain well? Is the lawn site sunny or shady? If sunny, will tree growth later make the area more shady? Is it important that the lawn remains green most of the year, or are extended periods of lawn dormancy and brown appearance acceptable? Is there any history of pest problems such as Necrotic ring spot? Is sod available or will the lawn need to be seeded? Your answers to these questions will help determine the most suitable lawn grass species for your situation.
