Question: I dethatched then applied a pre-emergent halt to prevent crabgrass. What is the minimum time I should wait to overseed?
Answer: Any time you apply Halts, you need to wait 4 months before seeding or sodding. The chemical remains in the soil for 4 months and will interfere with seed germination. Plan on reseeding this fall.
