When do you apply Certainty to sticker bushes?
Certainty Herbicide†is a post-emergent herbicide so this means it only kills weeds that are already emerged from the soil. You can spray Certainty Herbicide on a yard or target weed whenever the weed is actively growing. Refer to the product label for mix rates and cover areas.†
