How to Use SedgeHammer+
Open packet and pour into 1 gallon of water.
Mix the solution thoroughly. One packet will cover 1,000 sq ft.
DO NOT add any non-ionic surfactant -it is already included in the packet for easy mixing.
While spraying, periodically swirl or shake the mixture to keep the product evenly distributed in the water.
Do not store the mixed solution as it will degrade and become ineffective within 24 hours of initiating mix.
