Q
We want to apply Sedgehammer to the church garden. But also Milorganite. Does it matter in what order we do this?
A
I would apply the Milorganite first as it is a slow release fertilizer.
Yes, it will feed the nut-grass but I see that as a plus, because for SedgeHammer (a selective herbicide for nut grass) to work the nut-grass needs to be actively growing and the Milorganite will do this.
