Pre-emergent and post-emergent herbicides for crabgrass, broadleaf weeds, and total vegetation control
Preen
Pre-emergent weed preventer stops weed seeds from germinating for up to 3 months. Apply in spring before weeds emerge. Works in garden beds and around established plants — safe around 200+ plants. Does not kill existing weeds.
Scotts
Prevents crabgrass and 8 types of grassy weeds before they germinate. For NJ, apply mid-March to early April — when forsythia starts to bloom. 20 lb bag covers 10,000 sq. ft. Does not feed the lawn (pair with separate fertilizer).
Roundup
The most effective total vegetation killer for driveways, sidewalk cracks, fence lines, and garden edges. Glyphosate-based formula kills weeds down to the root. Visible results in 3 hours. One bottle makes up to 23 gallons of solution.
