I had some bare spots in my lawn (under a tree and spots I treated for weeds) so I put down some top soil and seeded with centipede seed around 4 days ago. Nutsedge was growing in a few of these spots I seeded so I bought a few packs of Sedgehammer. Can I spray the Sedgehammer in the spots where I put down seed 4 days ago? I think I should be good until the seed germinates, correct?
