- 1). Mow your lawn regularly to trim down the invasive broad-bladed grass and prevent it from going to seed and spreading throughout your yard.
- 2). Put on gardening gloves and rip the crabgrass out by hand. Grab the grass by its base, where it meets the soil, in order to remove it by its roots. Do not discard the broad-bladed grass in a compost pile; instead, place it in a plastic yard waste bag.
- 3). Mix the herbicide following the instructions on the container and pour it into a spray bottle. Spray an even coating of the herbicide on the offending grasses, making sure that the herbicide reaches the roots to kill them.
