Though artificial grass can get weeds, most artificial turf is far more weed-resistant than natural grass. If weeds start to pop up, you can remove them by hand or spray a weed killer and then use a rake to remove them once they’re dead. For extra help keeping weeds at bay, be sure to put down a layer of landscape fabric beneath the artificial turf or buy an artificial grass product with a non-perforated backing to help prevent weed growth.
