How to Kill Crabgrass Around Plants
- 1). Identify potential crabgrass around plants. Mature crabgrass has a star-shaped design made up of long, thin blades. In both earlier and later stages of growth, the crabgrass blades are always wider than normal grass blades. The crabgrass is usually green in color and may have offshoots from the center sprout comprising the center of the star shape.
- 2). Ensure the ground around the plant is dry. Carefully position the spray bottle with the nozzle a few inches from the dirt around the bases of the crabgrass shoots.
- 3). Spray in small, quick bursts directly onto the crabgrass and the dirt under the crabgrass blades. Be aware of which way the wind is blowing to minimize the amount of herbicide that gets onto plants and surrounding grass.
- 4). Allow the area to dry for 24 hours. For crabgrass that remains apply another round of spray, wait 24 more hours before proceeding again.
- 5). Use your hand to grasp the crabgrass that remains and pull it out of the dirt. Repeat until the crabgrass is no longer visible. Spray more selective herbicide on the spots where you pulled crabgrass. Water the plants again after 24 hours has passed.
