How long does it take for Sedgehammer to work?
Sedgehammer is absorbed into the leaf tissue within 24-48 hours and enters the vascular system. It travels to the base of the leaves where the growing point is located. Critical amino acid production within the plant is then halted. Yellowing and browning of leaves usually occurs within 10-14 days.

Will SedgeHammer work without surfactant?

Sedgehammer Herbicide must be applied with a non-ionic surfactant to ensure uptake. Use a 1000g/L non-ionic surfactant at 120mL per 100L. For handgun or knapsack application, add surfactant at 12mL/10L of water.
What’s the difference between SedgeHammer and SedgeHammer plus?
Sedgehammer + is considered one of the more “gentle to turfgrass” nutsedge killers and pets and people can return to the treated area once the spray dries. The “+” (plus) in SedgeHammer + indicates that it already contains a surfactant, so it is not necessary to use any additional products.

SedgeHammer Herbicide comes in a 13.5 gram packet that has a built in surfactant and only requires you to add to one gallon of water in your sprayer. The 1.33 oz bottle does not include a surfactant so we would suggest using the Non-Ionic Surfactant For Herbicides rather than dish soap.
