According to the Hi-Yield 2, 4-D Selective Weed Killer product label: Reseeding of lawns should be delayed following treatment. With Spring application, reseed in the Fall. With Fall application, reseed in Spring.

That's a long time. The longest most others say is between two weeks to a month. But if that's what it says, my next question is why is it that long? 2-4D won't even kill weed seed so why would it affect grass seed? And new seedlings still aren't broadleaf so would it still hurt them?

And if I cant spray, the weeds I have are morning glory, dandelion, clover, stickers, and a few misc weeds. Could I just mow really low, rake the crud out of them, and spray 2-4D once the grass seed has established?

My suggestion - go ahead and do the seeding now. Let the seeds get established. Worry about the weeds next spring. Start off with a pre-emergent and then followed by 2, 4D next spring. Everything should come out fine.
