Crabgrass is one of the most frustrating weeds homeowners face. It grows quickly, spreads aggressively, and can take over your lawn before you even realize it. If left untreated, it competes with healthy grass for nutrients, sunlight, and water—leaving your yard patchy and weak.
The good news? With the right approach, you can get rid of crabgrass permanently and keep your lawn looking lush and healthy all year long.
What Is Crabgrass and Why Does It Spread?
Crabgrass is a fast-growing annual weed that thrives in warm weather. It typically appears in thin or bare spots in your lawn where healthy grass isn’t strong enough to compete.
Common reasons crabgrass spreads include:
Poor lawn maintenance
Thin or weak grass
Compacted soil
Overwatering or underwatering
Lack of proper fertilization
Understanding why crabgrass grows is the first step toward effective crabgrass control.
Step-by-Step: How to Get Rid of Crabgrass
1. Apply Pre-Emergent Herbicide (Best Prevention Method)
The most effective way to stop crabgrass is before it even starts growing. Pre-emergent herbicides create a barrier in the soil that prevents crabgrass seeds from sprouting.
Apply in early spring before soil temperatures rise
Water lightly after application
Reapply if necessary based on product instructions
This is a key step in long-term crabgrass prevention.
2. Remove Existing Crabgrass
If crabgrass has already appeared, you’ll need to remove it immediately.
Pull it out by hand (including roots)
Use post-emergent herbicides for larger infestations
Avoid letting it go to seed
Quick action prevents it from spreading further across your lawn.
3. Strengthen Your Lawn
A thick, healthy lawn is the best defense against weeds.
Mow at the correct height (don’t cut too short)
Water deeply but less frequently
Strong grass naturally blocks crabgrass from taking over, making lawn weed control much easier.
4. Improve Soil Health
Crabgrass thrives in poor soil conditions. Improving your soil can significantly reduce weed growth.
Add organic matter or compost
Maintain proper pH levels
Healthy soil supports strong grass roots and prevents unwanted weeds.
5. Overseed Bare Areas
Bare patches are an open invitation for crabgrass.
Overseed in fall or early spring
Choose grass types suited for your region
Keep soil moist until new grass grows
This step helps fill gaps and prevents future infestations.
Common Mistakes to Avoid
Many homeowners unknowingly make mistakes that encourage crabgrass growth:
Cutting grass too short
Skipping seasonal lawn treatments
Watering too frequently
Ignoring early weed growth
Avoiding these mistakes is essential for long-term weed control success.
