How long after spraying do I need to wait to add mulch?
I have nutsedge in a flower bed with plants, and I need to mulch the bed. How long after I spray the nutsedge can I mulch? I assume I should spray and not remove the nutsedge immediately but wait several weeks after mulching to pull them?

Using SedgeHammer Plus Herbicide the nutsedge itself takes about 3-6 weeks to die in some cases, so realistically you could mulch pretty close after if you are mulching over where you applied the Sedgehammer and where the sedge is growing.
Is Sedgehammer safe to use in a butterfly-friendly garden? Will it harm visiting butterflies?
A
Since SedgeHammer Plus Herbicide does not have any insecticidial properties, it should not harm insects such as butterflies. However we would recommend spraying when they are not actively there. Also keep in mind that this product is not safe for ornamentals, only grasses
