roundup weed killer

Roundup products are labeled for use on hardscapes and landscapes: cracks and crevices in driveways, sidewalks and patios; along fences; in mulched beds; gravel areas; around trees and shrubs; flower beds; walkways; and edging.

Mix the concentrate per the product label. The label directions state to spray each gallon of spray solution over about 300 sq. ft.; a 32 fl. oz. bottle makes up to 5.3 gallons of spray and can cover up to roughly 1,600 sq. ft.

Roundup is sold as ready-to-use sprays and water-mix concentrates. Some ready-to-use options are packaged in pourable refill jugs intended to refill a sprayer or larger container.

Coverage varies by product: many ready-to-use containers cover about 250–300 sq. ft.; a 32 fl. oz. concentrate can cover up to about 1,600 sq. ft.; and larger refill jugs list coverage in the 5,000–10,000 sq. ft. range.

Prevention claims depend on the formula: some concentrates advertise up to 12 months of prevention, dual-action preventer formulas up to about 4 months, and a lawn-specific formula lists up to 3 months.

Wait times vary by formula. Some contact products allow planting within 1 to 30 days after application. Preventer formulas have longer restrictions—labels note ornamental bedding plants, trees, shrubs, sod and seed may need to wait about 4 months before planting. Always follow the specific planting intervals on the product label.

Timing varies by product: many listings say the spray becomes rainproof in about 30 minutes and can show visible results within hours (some note visible as fast as 6 hours). A lawn-specific option lists rainproof in about 3 hours and says it “starts working immediately.” Check the product label for exact claims.
