re: Question about seeding and weed control

Standard practice is to kill everything in the yard twice over with glyphosate.

Then seed, then keep the area damp for about two weeks (see YouTube. Seeding is a process).

You’ll have new weeds along with healthy grass at which point you will spray the weeds with something like Celsius, a selective herbicide (won’t kill most turf grasses).

But the most important questions are:
- where are you located?
- how much sun does your yard get?

Did you have a certain grass type in mind? Seeding as opposed to sodding will limit you.
