|You'll need to check the weed and feed package for waiting times. Some products contain a pre emergent herbicide which will keep grass seeds from sprouting. The waiting period is often about 4 weeks except in the case of a time release crabgrass pre-emergent such as Scotts containing Halts. If this is what you've used, the label recommends waiting 4 months before overseeding.
