How Do I Get Rid of Crabgrass?Updated 9 days ago

Crabgrass is a common lawn weed that can quickly take over if left untreated. Here's how you can get rid of it and prevent it from coming back:

1. Use a Pre-Emergent Herbicide

• Timing: Apply pre-emergent in early spring, before crabgrass seeds germinate. This is usually when soil temperatures reach 50–55°F for several days.  View your soil temperature map
• Product Suggestion: Use a pre-emergent like 13-0-10 Guardian Pre-emergent, which prevents seeds from sprouting.
• Pro Tip: Water the lawn lightly after applying to activate the herbicide.

2. Pull Mature Crabgrass by Hand

• When: For small infestations or when crabgrass has already sprouted.
• How: Pull the plants by hand, making sure to remove the entire root system. Use a weeding tool for stubborn plants.
• Tip: Pull crabgrass when the soil is moist to make it easier to remove.

3. Apply a Post-Emergent Herbicide

• When: If crabgrass is actively growing, use a selective post-emergent herbicide designed to kill crabgrass without harming your grass.
• How to Apply:
  • Spot-treat affected areas.
  • Follow the product instructions carefully to avoid damaging your lawn.
• Note: Avoid applying herbicides during extreme heat to reduce the risk of burning your grass.

4. Improve Lawn Health to Prevent Crabgrass

A healthy lawn naturally outcompetes weeds like crabgrass. Here's how to keep your lawn strong:

• Mow at the Right Height: Keep grass slightly taller (around 3-4 inches) to shade the soil and prevent crabgrass seeds from germinating.
• Water Properly: Deep, infrequent watering encourages deep root growth in your lawn, making it harder for weeds to thrive.
• Fertilize Regularly: Apply a high-quality fertilizer, such as 20-0-10 Almighty, to promote thick, lush grass that crowds out weeds.

5. Reseed Bare Areas

Crabgrass often takes root in thin or bare spots in your lawn. After removing crabgrass:

• Reseed those areas with a quality grass seed blend, such as your Envy Premium Tall Fescue Grass Seed Blend.
• Cover with straw or a light layer of peat moss to retain moisture.

6. Monitor and Repeat

• Stay vigilant during the growing season and remove new weeds promptly.
• Reapply pre-emergent herbicide annually to maintain control.

By combining these steps, you can eliminate existing crabgrass and prevent it from taking over your lawn in the future!
