Controlling weeds in Las Vegas take persistent work

The three worst weeds to control in home landscapes are common Bermuda grass, nutgrass and palm seedlings. Controlling common Bermuda grass and nutgrass organically requires persistence — knocking them back as soon as they appear until they finally start surrendering around late summer.
