Jeff from Budd Lake, New Jersey writes,
How long after application of Snapshot before I can overseed my lawn?
Since Snapshot is a pre-emergent, meaning that it prevents seeds from germinating, you should not apply any seeds you want to grow and germinate for awhile, since Snapshot will prevent them from germinating. For this reason, you should not overseed for at least 4 to 6 months after applying snapshot.
