And how long after that can I overseed my lawn?
It looks like the starter fertilizer you have will have quite a bit of N-P-K in it, while the Crabgrass Control Plus is only a 0-0-7 analysis. The extra potassium would not hurt your lawn since it is a pretty low addition, and you will not damage the lawn with the extra Potassium. Overseeding or new turf would be the concern, since you should only use a product like this containing Prodiamine on established turf (not new seeding) at least 60 days after seeding/overseeding. We would recommend waiting at least 3 months after using Crabgrass Control Plus before putting down any new seed.
