How long does Sedgehammer take to break down?
I had a bad infestation of nut grass in a garden bed which I have since sprayed. How long before I can safely use it as a vegetable garden?
We checked with the manufacturer on this one and they told us that the product can stay active in the soil for up to 3 years and a veggie garden should not be planted in this area for at least 3 years.
