    Q
    Can I spray Certainty safely on Zoysia that's just started to green up to kill annual blue grass?
    A

    Certainty Herbicide - 1.25 oz. is safe to apply on Zoysia but not if it is in a transitional state. You will want to wait till your lawn is fully green before applying any products on it or apply only as a spot treatment directly to weeds.
