There are several ways to kill crabgrass permanently, including:
-
Apply herbicide: As soon as you spot crabgrass, spray it with an herbicide. There are many options including chemical and natural solutions. Post-emergents attack crabgrass that has already sprouted. If you have a widespread crabgrass problem, using a pre-emergent is the best course of action.

Apply pre-emergent: Taking steps to get rid of crabgrass before its established is the only surefire way to stop it from overtaking your lawn in the summer. It will also kill the crabgrass permanently without killing your grass. Prevention is the best tactic.
-
Use baking soda: Baking soda dries and kills crabgrass permanently by targeting crabgrass at its central root while drying it up. Its best to attack the weeds early because theyre easier to control than mature ones. Typically, baking soda removes moisture from the leaves, stems, and roots, resulting in tissue damage and eventually the death of crabgrass.
-
Pull by hand: If you only have a few spots of crabgrass, you can try removing them manually by pulling them out by hand or using a garden weeder tool.
Its important to note that if you do decide to use herbicides, you should follow the instructions carefully and avoid applying them on windy days or when rain is expected. Additionally, if you have a widespread crabgrass problem, its best to consult a lawn care professional for advice on the best course of action.
