Does Sedgehammer need to be watered in?

Can I apply granular fertilizer or Essential-G on the same day as Sedgehammer?
- Yes. We recommend that granular fertilizer and Essential-G be applied before Sedgehammer.
Can I apply other liquids and Sedgehammer on the same day?
- Yes. We recommend applying non-herbicide products like like biostimulants and Primo Maxx growth regulator prior to spraying Sedgehammer.
How long does it take for weeds to die after spraying with Sedgehammer?
- It depends on the weed being targeted and temperature. Most weeds begin to yellow within 14 - 21 days of application.
Should I use surfactant with Sedgehammer?
- Yes. Sedgehammer produces best results when mixed with non-ionic surfactant.

- Yes. We don't recommend spraying your lawn with Sedgehammer when temperatures exceed 90F as injury may occur.
