Artificial grass lasts for years, is safe for kids and pets, wears well under hot sun and can be nearly as soft as real grass. It does not harbor pests like real grass does and can be installed over concrete. However, as with anything located outside, artificial turf needs some maintenance. Cleaning artificial turf will take only a half-hour or so a week, and it will keep the grass safe and looking good.
Pick up large debris.
Use a leaf blower to remove debris and also fluff up flattened grass. Blow toward the tips to make them stand up. Do this monthly, or more often if needed.
Pour white vinegar over areas where dogs urinate. Let it soak through, then rinse with water. Repeat monthly for one or two pets, or more often for more dogs.
Wash the grass once a week or as needed with plain water.
