Scotts Halts Crabgrass & Grassy Weed Preventer – Pre-Emergent Weed Killer for Lawns (Up to 10,000 sq ft, 20.12 lb)

Protect Your Lawn with a Smart Pre-Emergent Solution

Scotts Halts Crabgrass & Grassy Weed Preventer is a granular pre-emergent designed to interrupt the germination of a broad list of common lawn weeds. By targeting seeds before they sprout, it helps you maintain a cleaner, more uniform lawn throughout the season. This product is suitable for a wide range of lawn types, making it a versatile option for home gardens, enthusiasts, and grounds teams alike.

Seasonal Use and Timing

Apply in the early spring to a dry lawn for season-long prevention. For goosegrass, a follow-up application every 8 weeks helps maintain control. In fall (August–October), apply to prevent certain winter weeds and, in most regions (excluding California), moss growth. This approach supports a proactive weed program without relying on post-emergent tactics.

What It Protects Against

• Crabgrass, foxtail, spurge, barnyardgrass, fall panicum, goosegrass
• Oxalis and other listed lawn weeds
• In fall, Poa annua, henbit, corn speedwell, and chickweed (seasonal prevention)

Coverage, Lawn Types, and Weather

• One bag covers up to 10,000 sq ft
• Compatible with most grass types, except Dichondra or Bentgrass
• Performance is not diminished by rain, snow, or freezing conditions after application

Usage Tips and Important Notes

• Apply to a dry lawn in the approved seasons for best results
• Avoid applying to mature weeds; this is a preventive product for seeds
• For goosegrass control, consider a follow-up treatment after 8 weeks

With a single 20.12 lb bag, Scotts Halts offers a practical, broad-spectrum option to support lawn health while reducing the need for immediate post-emergent interventions. As with any lawn product, follow label directions for best results and consult local guidelines for region-specific recommendations.
