How to Kill Crabgrass in Bermuda Grass: 5 Easy Steps

Here’s a step-by-step guide on killing crabgrass in Bermuda lawn:

1. Choose a crabgrass killer that is safe for Bermuda

Buy a crabgrass killer that won’t harm your Bermuda grass. The best bet is a post-emergent herbicide with Quinclorac, like Ortho WeedClear (pictured below).

2. Choose the right day and conditions to spray crabgrass

Now that you have the appropriate herbicide, choose the best day and conditions for its application. The ideal day to spray crabgrass killer on your yard should be calm and wind-free, with a temperature below 90℉ (32℃). If you apply it on a windy day, the herbicide spray evaporates before the crabgrass absorbs it.

3. Water your lawn before herbicide application

After choosing the best day, water your lawn deeply 24 hours before herbicide application. The practice will keep your yard hydrated but not wet, making the weeds effectively absorb the chemical.

4. Spray your lawn

Dilute your herbicide according to instructions, then spray the crabgrass thoroughly. Ensure the crabgrass killer fully covers the leaves before moving on.

5. Allow time for the herbicide to work

For the herbicide to infiltrate the crabgrass, avoid watering the lawn for 24-48 hours after application. Also, avoid mowing the grass for two weeks to allow time for the chemical to kill weeds to the roots.
