When asked about turf grass lawns, some clients feel that they should have one but cannot provide a particular reason. "Because they're nice" someone once said to me. I don't think that is reason enough if there's no functional or aesthetic need for it. If a lawn fills a particular emotional need or is meaningful in some way, that is a different story. Unfortunately, the care required to keep them healthy makes turf grass lawns one of the least environmentally friendly growing things you can have.
