What’s the difference between crabgrass and orchard grass?
Crabgrass is an annual grass that germinates in the spring and grows during the summer months. We can help control crabgrass by using pre-emergence in the spring and spraying special herbicide in the summer. Orchard grass is a perennial grass that grows taller than your regular grass and year-round. There is no selective way to kill orchard grass without killing your lawn. To kill orchard grass you can spray roundup, then dig up and replant.
