This one really comes down to personal preference and the use of the lawn. Artificial turf will last decades in a space with low traffic. In a kids playground it can look worn out rapidly. Artificial turf also gets really hot in the sun in mid summer, no fun for kids and dogs. Real grass can get damaged by pets and high traffic, requiring regular maintenance and sprinklers. Ben’s recommendation: put artificial turf in front yards and us in areas for decorative greenery, install real grass for kids and dogs.
