What to expect in your yard

Weeds usually begin to wilt within hours, with many showing full browning within 1–2 weeks. The product’s unique formula starts working immediately, and you may notice visible results in as little as 6 hours in some situations. For best results, apply to actively growing weeds on a dry, leaf-free day and avoid spraying desirable plants.

Tips for best results

• Spray until thoroughly wet, targeting leaves and stems of the weeds
• Avoid spraying desirable plants, flowers, and vegetables
• Reapply as needed for persistent or new weeds
• Store upright in a cool, dry place away from children and pets
