Can I put down crabgrass preventer and grass seed at the same time?
A: You've got two options to have it both ways -- assuming you don't mind chemicals. One crabgrass-preventing chemical is siduron (Tupersan), which is able to stop crabgrass from germinating without affecting the germination of turfgrass. So you could put that down now and seed both. via
Will crabgrass preventer hurt grass seed?

When should crabgrass preventer be applied?
Apply your crabgrass preventer before soil temperatures reach over 55 degrees for 3 days. Crabgrass seeds start to germinate as the soil warms up. Initial emergence typically occurs when the soil gets to be about 55°F, and the majority of crabgrass seeds germinate between 60°F and 70°F. via
Will grass seed grow if you just throw it on the ground?

How do you get rid of crabgrass before seeding?
To combat these weeds and clear the area for reseeding, apply a pre-emergent crabgrass killer designed in the early spring. As the seeds try to germinate, they absorb the poison and die back.
